If you go to [https://addons.mozilla.org/en-US/android/] where I would expect only supported add-ons to appear, it seems not a single recommended add-on is compatible. If you then follow the hyperlinks at the top of the page, "To learn about add-ons compatible with Firefox for Android, click here", which eventually links to the "recommended Extensions program" at [http://example.com https://addons.mozilla.org/en-US/firefox/search/?recommended=true&type=extension], none of those work either. Even though I have uBlock installed and its recommended, when I open the extension page I still get the prompt "Not available on Firefox for Android..." It seems like that extension was only installed because it was tied to my mozilla account. I cannot find a list anywhere of apps that are supported on Firefox 80.
