Google Meet does not work in Firefox. How to enable a microphone in Google Meet

How to use Google Meet: how to establish, create a meeting, show a presentation

Google Meet is a video conference service. We wrote that it has recently become free and now it is a good alternative to Zoom.

In the article we will tell you how to install Google Meet and go through the main functions.

  • Budget from 3000 euros is much cheaper than working directly.
  • For legal entities and individuals. legal entities can get closing documents, compensate VAT. Individuals can start advertising without communication with managers.
  • 3 payment methods. pay for advertising by a card of an individual, from the accounting account of the organization, electronic money.

How to download and install Google Meet: instructions

To work in Google Meet, you need to have personal or corporate mail to Gmail. If you don’t have it yet, you need to get it.

You can use Google Meet online in a browser or download the application to your phone.

On computer

A separate application is not provided for the computer. we use the service online in one of two ways:

  • We go to our mail to Gmail, the Meet tab is installed in the left panel by default. click “Start the meeting” to launch our conference or “switch to a meeting” to become a member of a stranger. After that, we are transferred to the service website.
  • Or go immediately to the service website by direct link and click “Start the meeting”.

P.S. Google Meet does not work with all browsers. only with Chrome, Mozilla Firefox and Microsoft Edge.

On the phone

We find an official application. For Android. on Google Play, for iPhone. on the Apple Store and click “Install”. Install like any other application.

Open, pass welcome windows (we click “Next” everywhere).

The application immediately connects to Gmail by mail, that is, you do not need to enter mail/password. In the application, you can turn off/turn on the microphone and camera, go into other people’s meetings. for this, click the “Code of the Meeting” and enter the code that the author of the conference sent us. To start our conference, we click “New Meet”.

We briefly list the functionality of the mobile application. each function is described in more detail below in the section “How to use Google Meet to work”:

  • switching the camera from the front to usual;
  • subtitles;
  • screen show;
  • Turning on/off the microphone;
  • list of participants;
  • chat;

Also in the application you can view the finished meetings. There are fewer functions in the application than in the online version.

Why is it worth using Google Meet:

  • service is free;
  • You can use online or through a mobile application;
  • unlimited number of meetings;
  • conferences up to 1 hour with a capacity of up to 100 people;
  • there is extended functionality for corporate customers, organizations and educational institutions (paid tariff);
  • automatic subtitles (so far only English is maintained);
  • encryption when transmitting data and in standby mode;
  • can be synchronized with Google calendar.

Check the confidentiality settings Firefox.

Note. This is applicable to the MAC under the control of MacOS Catalina V10.15 or newer. If you use Firefox on a computer with Windows, follow other corrections specified below.

Apple believes that the contents of your screen should be confidential. Without permission to write the screen of your Mac, functions such as the joint use of the screen will not work. If you unsuccessfully tried to present your screen in Firefox, make sure that the browser can capture the image of your Mac.

Launch system settings and select “Security” Privacy. ‘

On the Confidentiality tab, select the “screen recording” on the left panel.

Finally, make sure Firefox is checked.

You will be invited to close Firefox so that the changes come into force. You can do this by clicking the “Excuse and Open” button in the invitation.

We recommend restarting Firefox manually so that you can properly maintain any current work in the browser.

Providing a resolution of Meet Share for the joint use of the screen

Like other popular web browsers in the market, Firefox also allows you to capture and share your window or all computer screen with supported websites. If you are faced with any obstacle when trying to share your screen on any website, check the permissions of this site to jointly use the screen. Go to the Google Meet tab and follow the following actions.

Click the right mouse button anywhere in the Google Meet page and select “View page information”.

Step 2: Go to the “Resolution” tab.

A list of permits related to Google Meet in your Firefox browser will open.

Scroll the permissions and set the “use by default” checkbox to resolve the “joint use of the screen”.

This gives Google Meet access for recording and demonstrating your screen of D ring of presentations. If turned on, remove the flag and install it again. In addition, when it is proposed to provide Google Meets permission to view your screen, make sure you have chosen to “allow” after choosing a screen/window for joint use. Very important.

Provide permission to demonstrate the Meet screen

Like other popular web browsers in the market, Firefox also allows you to take pictures of the browser window or the entire computer screen and share it with supported websites. If you encounter any obstacle when trying to share your screen on any website, check the permissions of this site for the joint use of the screen. Go to the Google Meet tab and follow the following actions.

Click the right mouse button anywhere in the Google Meet page and select “View page information”.

Go to the “Resolution” tab.

A list of permits related to Google Meet in your Firefox browser will open.

Scroll the permissions and install the “use by default” checkbox to “share the screen” to resolve.

This gives Google Meet access for recording and demonstrating the screen during presentations. If turned on, remove the flag and install it again. In addition, when it is proposed to provide Google Meets permission to view your screen, make sure you choose to allow after choosing the screen / window that you want to share. Very important.

Try safe mode.

Firefox additions are cool. They increase performance and improve your impressions of watching web pages. Despite their advantages, these superstructures sometimes violate the work of some browser functions. Try to use Firefox without any superstructures and see if this will solve the problem of sharing Google Meet screen. However, you do not need to delete your superstructures. Just run Firefox in safe mode, the mode of elimination of the problems that temporarily disconnects all the superstructures.

Launch Firefox and tap the hamburger menu icon.

Select a certificate from menu options.

Then select information about the elimination of problems.

Now click the “Reload with disabled superstructures”.

In the confirmation request, select “Reload”.

Note: restarting the browser will restart all active Firefox windows. So, before continuing, make sure you have all the current affairs.

A large.scale failure occurred in the work of Google services

About 14:50 in time, all Google services turned off. YouTube stopped opening, Gmail did not work, it was impossible to open documents on Google Docs. Global failure: he touched users around the world. It took more than half an hour to restore normal work.

Search on the main page of did not stop work. At the same time, the user remained goggle on it. the authorization page in Google also disconnected.

Google’s own status page for some time with green indicators claimed that there were allegedly no malfunctions, but at about 15:15 Moscow time caught fire.

The reason for the disconnection may be related to the GAIA authorization service: the services continued to open when the user is not logged in. YouTube worked in browser incognito browser. videos on other sites also continued to function.

Downdetector aggregator data show that users around the world have reported the inaccessibility of Google services. This is not regional inaccessibility: they complained about Google problems in the USA and Western Europe, and asks to knock, because a smart call does not work due to the disconnection of Google. Microblog Rubengmrs

The Google Meet online video is disconnected, in which many are now studying and working. “Assistant” did not answer questions. At least one owner of smart switches spent an hour in the dark. the Google Home column was controlled by lamps. The Nest offline chambers have gone, no longer protecting smart houses from robbers.

Internet of Shit microblog screenshot

Hoogle employees also affected the problems. In response to a commentary request, one of the company representatives said that he could not open mail. The company assured that they know about problems.

The search itself did not “fall”, although it lost part of the functions. In 2013, a two.minute shutdown of Google search.COM has led to a reduction in world traffic by 40 %. Probably, for seven years of architecture development, this incident has taken into account.

Updated 15:30 Moscow time: Google resources have restored functionality. Contacts in Gmail still do not work.

Updated 15:55 Moscow time: a warning about the impossibility of working with contacts has disappeared from Gmail. The company has not yet released a technical report on the reasons for the disconnection and has not called at least a preliminary reason for the problems.

Updated 20:50 Moscow time: due to a failure for the interval of less than an hour, YouTube traffic fell to 56 % of its usual values. These are these monitoring platforms Kentik.

Google apologized for the inconvenience and confirmed that the cause of the malfunction was hidden in the authentication service. She turned off at 14:47 in time and “lay” ¾ hours due to internal problems of the quota quota. At 15:32 Moscow time, the problem was solved, and Google’s services earned.

Why the sound does not work

There are several reasons why there may be no sound in the Google Meet application. Everyone will be considered in detail.

The user or the user himself turned off the microphone

In the event that all group communication participants do not hear the interlocutor, he needs to see if the microphone is included on the laptop, phone or PC. The desired icon can be found in the window of the Google Mit application.

If the icon is crossed out, the microphone does not work at the moment, that is, turned off. Therefore, you need to click on the icon and turn on the sound.

The microphone is not configured

This means that the sound in Google Mit is not transmitted and does not come to the interlocutor. If in the application menu the icon responsible for the sound accompaniment of the conversation will not be crossed out, but there is no sound, you will need to see and if necessary change the microphone settings.

  • On the usual computer device with the right mouse key, click on the icon depicting the speaker. It is located in the tria (right lower angle PC, where the language panel).
  • Here we select the item “Record devices”.
  • Then, double pressing the microphone, activate the “Properties” window, and then select the tab with the name “Levels”.
  • Now you need to check whether the microphone is turned on or not.
  • After performing the settings, click OK.

If necessary, you can set the required volume level.


On the phone with the Android system, the order is as follows:

  • We go into settings, select the “Privacy” tab.
  • Then click on “Determining Management”, then to the “Microphone” tab.
  • And here we allow Google mit access to the microphone of the mobile device.

Check other settings

If the sound does not work, just in case you need to check other devices on which you can turn on or off the microphone. These include the keyboard, speakers, amplifier and volume control.

Why the interlocutor is not heard

In the event that the speakers or headphones do not work in the Google Mit application, you can eliminate the problem in several ways:

  • Checking speakers. This must be done to make sure of performance. Everything is simple. any video or music is reproduced, and if the sound is coming, then the speakers are serviceable.
  • Reinstall the Google Meet app or computer. We delete the application and install it again. And most importantly, you need to make sure that the latest version of the program is established.
  • In some cases, a simple reboot of the phone or computer helps.

If the problem with the sound is not at all able to solve the problem, and the interlocutor still does not hear the participants in the conversation, it is worth using another way-it involves turning off the conference subtitles. To do this, you will need to find three points located in the lower right corner on the Google screen on Google, and then click on the “Turn on Subtitles” tab.

Most likely, after all the manipulations done, users of the Google Meet application will be able to eliminate the problem with sound and establish the work of the microphone and speakers.

Sound connection via the phone

If it did not help and this, you can leave the video on a PC or laptop, and connect the sound through a mobile device. On the main screen of the video statement there is a dedicated line “Join the phone in voice communication mode”.

How to do it? Having click on the line, follow the instructions:

  • Choose the country from the list.
  • Enter the specified number on your phone.
  • In a couple of seconds, a window will appear: you need to enter a PIN code indicated on the main screen of the video chat of your PC.

Disconnecting the sound of video meetings

Another reason why you are not heard. the interlocutor could accidentally turn off the sound of a conference. This function is available only in the Google Meet mobile application.

In this case, for unlock on Android:

  • In the upper right corner, press the speaker on the badge;
  • A window with possible functions will appear;
  • To turn on the sound, press the “speaker” and check the volume on the device.

This should be done by the participant in the meeting that does not hear you.

Profile analysis

You need to see too many samples, but the calls of the calls are streamlined, so you can detail only the most loaded. I did not find anything in the first Chrome process, but in the second something was found:

I realized that 124 Samlov in Kipagefault deserve study. Most of the work with the intensive use of CPU in this trace was important and inevitable, but I had a suspicion that these samples are a job that can be avoided. Something I can fix. And although they made up only 0.75% of samples, I suspected that they indicate several greater costs.

I immediately realized their importance, because something similar saw earlier. Kipagefault means the processor turned to the memory that was allocated, but at the moment does not belong to the process. Perhaps the pages were removed from the process to save memory, but in the active process by car with a large amount of memory, this is pointless. It is more likely that this is a recently highlighted memory.

When the program selects a small amount of memory, the local memory manager (sometimes called a “bunch”) usually has some accessible volume that it can convey to the program. But if he does not have a suitable memory block, he will ask some part of the operating system (OS). If the program selects a large amount of memory (more than 1 MB or so), then a bunch will definitely ask for more memory. This is a relatively cheap operation in itself. A heap requests some memory from the OS, the OS says “of course”, then the OS notes the fact that it promised memory, and everything. At this time, the OS actually does not provide the program with any memory. So the world works in Windows, Linux, Android, and this is good, but it can confuse and surprise. If the process never turns to memory, then the memory is never added to the process, but if the process really turns to memory, then it is provided with separate pages of zeroed memory. They are called Demand Zero Page Fault, because the wound pages are “inserted” into the process on request.

In other words, the allocation of a large memory block is quite cheap, but in fact it does not provide the promised memory. Then, when the program tries to use the memory and the CPU discovers that there is nothing at this address, it launches an exception that awakens the OS. OS checks its notes and understands that in fact she promised to place memory at this address, so she puts part of the memory there and restarts the program. This behavior is easy not to notice, since it occurs very quickly, but when profiling, this manifests itself as samples that fall into Kipagefault.

This bizarre “dance” is repeated again for each dedicated block of 4 KB (4 KB. This is the size of the pages on which the CPU and the OS are working).

The costs are small. During the 10-second period, only 124 samples, which is about 124 ms or 0.124 seconds, got into Kipagefault. The total cost of the external function of Copyimage_sse4_1 was about 240 ms, so more than half of this function accounted for pages, but hardly a quarter of the cost of the Onsample function in line 15.

The total costs of these page mistakes are modest, but they hint at many other costs:

If this memory is allocated again (presumably each frame), then it should also be freed by each frame. In line 26, we see that the Release function, which frees memory, uses another 64 sample.

Когда страницы освобождаются, операционная система должна обнулить их (по соображениям безопасности), чтобы они были готовы к повторному использованию. This is done during Windows System. almost completely hidden costs. Of course, when I looked into the System process, I saw 138 samlov in Mizeropagethread. I found that 87% of Kipagefault samples in the entire system were calling Copyimage_SSE4_1, therefore, presumably 87% of 138 samples in Mizeropagethread were related.

I analyzed these hidden costs for the allocation of memory on the blog of 2014. The basic architecture of Windows has not changed since then, so hidden costs remain about the same.

In addition to CPP samples, my ETW trace contained calls for each VirtualALLOC call. This screenshot WPA shows a 10-second period during which the ONSAMPLE function performs 298 memory discharge, each of 1.320 MB, about 30 per second:

At the moment, we can evaluate that the cost of these repeated grades of memory is 124 (page refusal) plus 64 (release) plus 124 (87% of zeroing samples), only 312 samples. This gives us up to 1.9% of the total costs of the processor to the work of the video conference. Corrections, of course, will not change the world, but they are worth.

But wait, that’s not all!

We block the buffer to view its contents, but it turns out that we do not want a blocking call to copy the buffer. We just want a blocking call to describe to us a buffer so that we can look at it on the spot. Therefore, the entire cost of the MFCOPYIMAGE call. Waste! This is another 116 samlov. In addition, CMF2DMediabuffer :: Unlock in line 26 has another CMF2DMediaBuffer call :: Contiguouscopyfrom. This is because UNLOCK calls that we could change a copy of the buffer, so it copies it back. So 101 sample. Also garbage!

If we can check this buffer without a dance from Alloc/Copy/Copy/Free, then we will be able to save 312 samples plus 116 samlov (the rest of the copy cost) plus 101 sample (the cost of reverse copy) for total savings of 3.2%. Gets better and better.

Please note that selective data are reliable only statistically, and actual interest differs significantly depending on the computer and a specific workload. But the essence remains that this is not a cardinal, but a change that deserves attention.

Despite the fact that I spent years in the business of video games, my knowledge about the API blocking and unlocking the graphic buffer is very weak. As a result, I relied on the wisdom of my subscribers in. To come to the conclusion that copying could be completely avoided, and get an approximate way, how can this be fixed. After registering an unnecessarily detailed error report, I delegated the task of correcting it. The change appeared in the M85 and was recognized as quite important. to bet it in m84.

You need to be very attentive to see the difference. distributed between the Chrome process and the system process. But I hope that this helped some computers to heat less and work longer from batteries. And although this inefficiency was discovered in the profiling of Google Meet, improvement actually benefits any product that uses a webcam inside Chrome (and other Chromium browsers).

Why is the Google Meet camera does not work for me?

When we wrote about the most popular articles with the advice and recommendations on Google Meet, some people returned to us and asked why their camera in Google Meet does not work. Well, the problem with the Google Meet camera has several reasons, and in this article we will consider all possible causes and decisions. But before that it is important to take into account some of the main points because of which the Google Meet camera does not work:

Google Meet Your mic muted by your system setting.

  • First, check if you are connected to the Internet and whether the speed / connection is enough for the Google Meet video call.
  • Check if the camera works with other solutions for video conferences, such as Microsoft Teams, Zoom and T. D.
  • Then try the old, good universal solution of restarting the device.
  • Finally, check if any other application / software (for example, Snap Camera) uses the camera of your device, and turn off them all.

Here are a few main checks that you need to do. If this does not solve the problem of failure of the Google Meet camera, read on while we try to dig deeper and consider other possible causes and corrections.

How to fix the non.working problem with the Google Meet camera?

Therefore, if you are faced with this error on Google Meet on your Mac or Windows computer, the following solutions should help you correct it.

Give Google Meet access to your webcam.

One of the common reasons for the error of the camera failure in Google Meet is a blocked camera resolution. Although you really need to provide access to the camera for Google Meet at the first use, you may accidentally ban / block its permission to access the camera if you are dealing with several video conferencing services in your browser.

To make sure this is not the cause of your problem, check the solving Google Meet camera in your browser camera settings. Here’s how to do it in different browsers.

  • Chromium browsers (Brave / Google Chrome / Microsoft Edge / Vivaldi):
  • Press the button with three points in the upper right corner of the browser and select the settings.
  • Go to privacy and safety and select the site settings.
  • In the list of available sites, press the arrow button next to
  • Click the arrow of the opening list next to the camera in the partition of the section and select.
  • Fire Fox
  • Open a hamburger-manager in the upper right corner of the browser and choose preferences.
  • Click on confidentiality and security from the left panel.
  • Scroll the right window down to find permission.
  • Click on the settings button next to the camera.
  • Click on Meet.Google.COM and select allow to let the opening menu.
  • Safari
  • Click the Safari menu and choose preferences.
  • Click on sites for viewing permits for different websites.
  • Click on the camera on the left panel.
  • Click on the arrow of the opening list next to in the right window and choose to allow from the submenu.

Make sure your webcam is not used anywhere else.

If several applications for video calls and Google Meet are simultaneously launched on your computer on the browser tab, you can get the camera failure in Google Meet if it cannot access your webcam. This is the most common reason for the camera problems in the Meet or any other video call application. This happens when one of several video conferences in the background turns to your webcam and unintentively blocks its access for other applications.

It is best to determine in such a situation whether the webcam of your device is used somewhere else. To do this, just check the condition of the LED next to the webcam. If it is turned on, this means that your device has an application that turns to the camera, and in this case you need to find this application and close it.

If it is turned off, you may need to check it in your browser. Since in this case, if the Google Meet is open on one browser tab, and some other video conferences are open on different tabs, Google Meet may still not get access to your camera if it is used by another service.

To solve this problem, close all other tabs in the browser that can interfere with the access to the Meet webcam.

Reload the web browser.

Web browsers, such as Google Chrome, Firefox and Safari, can often face random failures and interfere with certain elements of the system. It is known that Google Meet is a victim of such failures that do not allow him to access the chamber or microphone of the device.

Therefore, if you see a black screen or a camera error, and not one of the corrections has helped, close all the tabs in your browser and restart it. If you use Mac, you need to get out of the application, and not just get out of it (using the X button) to completely close it. In the Google Chrome browser, you can also try to go chrome: // Settings / System and turn off “Use hardware acceleration, if available” option. It will also lead to the restart of the Chrome browser.

Also make sure Google Chrome, Microsoft Edge or any browser you use is updated to the latest version. You can turn on the automatic update in these browsers so that the latest version is always installed in them.

Allow the camera in Windows settings.

Windows parameters provide several parameters to turn on or disconnect the device camera.

  • To access the settings menu, press Win I and go to the confidentiality of the camera.
  • You must check the following settings on the right.

Make sure access to the camera for this device is turned on. Or click the “Change” button to change the setting.

Make sure to allow desktop applications access to the setting camera is enabled. Otherwise, turn it on by pressing the corresponding button.

Set the default webcam.

If you use Google Meet on a laptop connected to an external device, or if you are on a desktop computer and several sources of cameras are connected to it, this can create a scenario in which the Google Meet cannot easily determine your default webcam and may encounter with mistakes.

In such a situation, you need to clearly specify the default webcam so that Meet can easily identify the source channel of your computer. To do this, follow the following actions.

  • Open Google Meet and press the gear icon in the upper right corner to open the settings.
  • Choose a video from the left panel.
  • Click on the opening button below the camera in the right window and select the camera from available options.

Check the Internet stability of the Internet

Every time the program does not answer or fly out, the first thing to think about is about the stability of the access point when checking the Internet connection:

  • If you work on Wi-Fi-check the router, restart it;
  • If you use a mobile Internet. check the presence of gigabytes, turn on and turn off the access point, in the end, reboot the phone and try to enter the video conference again.

Clean the cache

Cleaning of castle data from the history of the browser and the Google Meet application itself is another way that can return the camera’s performance.

In the event that the user operates the Chrome browser to work in Google Meet, here is the instruction for cleaning the cache:

  • Go to the “Settings”, after. to the “Clean history” tab “Privacy and Security”.
  • Mark the point “Cash images and files” (or something similar)-other items can not be noted.
  • Click “Clear data”.

Now you should close all the tabs and restart the personal computer. After rebooting, try to again enter the video conference using the camera.
