WebRTC protocol in Mozilla Firefox browser

To enable WebRTC protocol properly in Mozilla Firefox browser, follow these 5 steps:

Update Mozilla Firefox: Make sure you have the latest version of Mozilla Firefox installed. This ensures that you have the most up-to-date WebRTC support. To update Firefox, click the menu button (three horizontal lines) in the top-right corner of the browser, go to «Help,» and then click «About Firefox.» Firefox will check for updates and install them if available.

Check WebRTC settings: By default, Firefox should have WebRTC enabled. To verify this, type «about:config» into the address bar and press Enter. Click «Accept the Risk and Continue» to access the advanced settings. In the search bar, type «media.peerconnection.enabled» to find the relevant setting. If the value is set to «false,» double-click it to change it to «true.»

When prompted by a website that uses WebRTC, make sure to allow access to your camera and microphone. You can also manage these settings by clicking the lock icon next to the website's URL in the address bar and selecting «Permissions.»

Check for browser extensions: Some browser extensions might interfere with WebRTC functionality.

To do this, click the menu button (three horizontal lines) in the top-right corner of Firefox, go to «Add-ons and Themes,» and click «Extensions.» Disable extensions by clicking the toggle switch next to each one, then restart Firefox and test WebRTC again.
