Hi Johan You mention that you have rooted your device - what changes have you made?

Hello,

I rooted my device with magisk delta, and then installed PIF (https://xiaomi.eu/community/threads/installing-magisk-and-play-integrity-fix.70553) & NOTOCJK (full weight font patch) modules and swiftbackup app, adaway app

After that I installed firefox from Google Play.

BTW I unrooted & re-locked my POCO device afterwards, and then installed firefox app again for test. However, the problem remains...

(update) I found I can launch firefox app normally if clearing all its data and reboot my device, unless I reboot my device again. A pity once I do so and then launch firefox, it will start to be force closed again.

Therefore, I cleared firefox's data (app kept) and launched it so as to tap "Crashes" in firefox's settings to send Mozilla a crash report. However, no report found in it. (Due to removal of app data...?) But without clearing it, I can't launch firefox (force closed) to tap "Crashes" to get the crash report. Falling into a dilemma now...

Any idea of how to make app traces or collect bug reports in such case? Many thanks.
