Firefox for Android Support Forum

I have a Blackview Tab16 (10" screen), which I bought last year; it was running Firefox quite happily until a couple of months ago. Now when I click on the icon, I get a sort of 'welcome' screen (with some message about a search widget?) for a fraction of a second, then FF closes and I get an error message saying 'Sorry. Firefox had a problem and crashed.' The version of FF is 126.0. I was told to try clearing the cache, but there is nothing there to clear! The tablet is running Android 12 / DoKe OS V3.0.

I have an 8" Blackview tablet which - despite needing to be plugged in to run all the time! - opens & runs Firefox perfectly happily. It's my main browser on my MacBook as well, and will run on my iPhone.

When I put a video or an image gallery to full screen, the navigation buttons, clock, and status bar don't hide.

They often appear as though they're going to hide, for a split second, but frustratingly bounce right back into view.

On rare occasions, it seems to be random chance, the status bar, clock, and navigation buttons do hide, but I don't know how to get them to hide every time.

I've already tried disabling picture in picture for the app but that has not helped.

What are the reasons the buttons and clock would not hide in full screen? How would we go about fixing things?

I have had this problem on two separate midrange samsung phones now: after about an hour of browsing, firefox slows down considerably. Pages take a long time to load and tapping input registers erratically, sometimes i tap a link and after a few seconds a different link opens, as though the tap was registered from a different spot on the screen. This is happening even on a brand new phone, and after emptying the cache. I wish I could keep using this app because of privacy concerns but it is genuinely unusable for me now. This problem has cropped up in the past half a year

Firefox just used almost a GB by just opening it! I only typed a Google search, and the next moment my phone tells my I'm out of data!

Note that this is foreground data, not background data. I googled and found answers about media playing in the background, but I haven't watched anything recently, so no streaming link should be active. I installed Ublock origin so I hope that might help.

Attach is my Firefox data usage for the past week of barely using it, except for an occasional Google search.
