You need Firefox 68 ( fennec 68.11.0 ) to use extensions from the open internet. Mozilla axed general extension support in later versions of their android browser.

I just keep it around next to my regular browser for the occasional paywall.

Thanks, I'm not sure if I want to run a browser that old though... Security-wise. Even if it's probably ok now, it's never going to get updated.

I wish they just supported sideloading of extensions. I wonder how developers are supposed to test their stuff on mobile.
