There are many reasons why this is happening. First, opening multiple Firefox windows on your computer might disrupt Google Meet’s screen sharing permissions. Second, the screen sharing issue could be a temporary device issue. Therefore, before implementing the solutions below, close all Firefox windows and restart the browser. If the problem persists, one of the troubleshooting checks in this guide should resolve it.

1. Check Firefox privacy settings

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

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