Problem with firefox Android

I am running firefox beta, and enabling custom addons to use my addon collection: each time i download something the .telephone app crashes but also notice my sim networks restarting, losing connection (when using data) in the process. also i deleted some bloatware from my phone using adb, although didnt touch any google packages, just bloatware like health apps and whatnot. is there something to be done about this ? thanks Phone: Infinix hot 11. no crashing with others random browsers (not mozilla thou, i have mozilla nightly and suffers the same issue)
