Does Mozilla offer somewhere to download older versions of Firefox for Android? I've had problems since November when I got this phone and downloaded the latest version of Firefox and every update since with no fix. I'm not able to view comments or make a comment on YouTube. Other people here have the same problem. I've disabled add-ons, uninstalled and reinstalled Firefox. There's also an annoying Firefox pop-up when viewing videos in full screen that can be fixed by adjusting a setting in about:config but I've just discovered about: config has been removed!!! 90% of my internet usage is YouTube using Firefox for Android, so the problems are significant to me. An older version works perfectly on my older phone and would like that version on my new phone. Is there a way I can do this? Thank you.
