Since version 134 of Firefox Android has been out, it crashes EVERY TIME when I try ot use the "back" gesture on my Xiaomi 14(i.e. swiping from right or left side of the screen) I tried Firefox 134, Iceraven 2.27 (also based on the same Gecko) - they act the same. In the same time I also have Waterfox, based in the previous version of Firefox 133, and it responds properly. I guess it is related to the latest version only. Here's the crash log:

Firefox on Android 134 is crashing when closing. This could be due to a variety of factors, such as corrupted app data or outdated software. Try clearing the app cache and updating to the latest version. If the issue persists, reinstalling the app might help resolve the problem.

No, this wouldn't solve the problem. What concerns me is the fact that there is a pattern. It happens on different software (Firefox, FirefoxBeta, Iceraven) ONLY based on version 134. Older versions do not have the same problem.
