Olanrewaju Sodiq

For many reasons, screen-sharing has become one of the most important features to look out for in a video conferencing tool. Google Meet offers the ability to share screens during a presentation but it has some shortcomings. For example, some Google Meet users can share their screens on all browsers but Firefox. If you're in a similar predicament, we've listed four things you can do to correct the anomaly.

There are many reasons why this happens. Firstly, having multiple windows of Firefox opened on your computer could mess with Google Meet's screen-sharing permissions. Secondly, the screen-sharing issue could be a temporary device glitch. Therefore, before you implement the solutions below, close all Firefox windows and restart the browser. Should the issue persist, one of the troubleshooting checks in this guide should get it fixed.

1. Check Firefox's Privacy Settings

Note: This applies to Mac running the macOS Catalina v10.15 or newer. Proceed to other fixes below if you use Firefox on a Windows computer.

The content of your screen, Apple believes, should be private. Without permitting an app to record your Mac's screen, features like screen sharing won't work. If you tried to present your screen in Firefox without success, check that the browser can capture your Mac's display.

Step 1: Launch System Preferences and select 'Security & Privacy.'

Step 3: Finally, make sure Firefox is checked.

You'll be prompted to close Firefox to effect the change. You can do that by tapping the 'Quit & Reopen' button on the prompt.

We recommend restarting Firefox manually so you can properly save any ongoing work in the browser.

2. Grant Meet Share Screen Permission

Like other popular web browsers in the market, Firefox also lets you capture and share your browser window or entire computer screen with supported websites. If you encounter any stumbling block while trying to share your screen on any website, check the site's screen-sharing permissions. Go to the Google Meet tab and follow the steps below.

Step 1: Right-click anywhere on the Google Meet page and select 'View Page Info.'

Step 2: Navigate to the Permissions tab.

That will reveal the list of permissions that pertains to Google Meet on your Firefox browser.

That grants Google Meet access to record and share your screen during presentations. If enabled, uncheck the option and check it again. Additionally, when prompted to grant Google Meets permission to see your screen, ensure you select Allow after choosing the screen/window to share. Very important.

3. Try Safe Mode

Firefox add-ons are cool. They boost productivity and enhance your web surfing experience. Despite their benefits, these add-ons sometimes disrupt some functions of the browser. Try using Firefox without any add-ons and see if that fixes the Google Meet screen-sharing issue. You don't have to uninstall your add-ons, though. Simply run Firefox in Safe Mode, a troubleshooting mode that temporarily disables all add-ons.

Step 1: Launch Firefox and tap the hamburger menu icon.

4. Refresh Firefox

This is another effective troubleshooting solution to big and small Firefox problems. Refresh, in this case, is simply another word for reset. And by following the steps below, you'll be resetting your device's Firefox back to its default settings. It will retain personal data like bookmarks, passwords, cookies, and download history. While refreshing Firefox will remove all extensions, website permissions, and other customizations.
