I use Android 5.1.1 This is the link i got when used about:crashes https://crash-stats.mozilla.org/report/index/f255fc18-de5e-4639-a6f4-9c38d0211011 btw when i did that just got little time to copy it, then it crashed again xD I think it started with the 93.0 version update, it was working fine before that. I tried: clean install: cleared the app data, uninstalled the app. Then installed it again. In the mean time i tried using Opera, Chrome and Kiwi , they work with no issues, but i like Firefox. I think it may be cause my old android, i hope is not that.
