Accessing about:config on Firefox Android (August 2020)

more options

How can I access about:config on Firefox Android? I've updated it to latest version (17 August 2020) but every time I try to open about:config in address bar, it can't complete request.

I also need to configure DNS over HTTPS on Firefox Android. How to do this?

Hi

You can access about:config in the Nightly build of Firefox for Android, available from the Google Play store .

I hope that this helps.

The about:config page no longer exists in this version for Android. So the procedure to enter the syncserver URL is now as follows:

   Go to Settings
   About Firefox
   Click 5 times on to the Firefox logo until Debug menue is enabled appears
   Go back to settings
