App "minimizes" when video goes fullscreen

Sometimes when I click full-screen on a video, the app view disappears, and I am back out on the home screen. I still hear the video, and can switch back to Firefox and try full-screen again. It usually (maybe always) works the second time.

When it happens, I can briefly see the video go full-screen and rotate to landscape. When the view has disappeared the screen rotates back to portrait. Whenever a video stays in portrait mode when going full-screen, the problem does not occur.

Even when closing firefox, I can still hear the video. So I think it is related to this issue: [https://support.mozilla.org/en-US/que.../1420245]

What I have tried:

  • Switching versions of firefox, they all have the same issue; Firefox, Firefox Nightly, and Fennec.
  • Clearing cache and disabling add-ons has not worked, but seemed to make it happen less frequently for a while (not sure).
  • I tried activating automatic screen rotation, but this made the problem worse. It would then not work the second time and firefox would only display part of the website in the top right corner of the screen. Closing it and re-opening it multiple times did not work. I had to turn auto-rotate back off.
  • I'm using the KISS launcher. Tried switching to various other launchers, but it made no difference.

not sure if fixed or not, but the problem did not occurred for me all day yesterday (after a couple of updates). whenever it would normally happen, the phone is simply slow to enter full screen mode.

it still does not happen today, i consider this fixed.

edit: never mind, problem is back..

after another update, the issue is back.

it might happen less frequently, but it has definitely not been solved.

Oh my. I have this problem too. It is so annoying that I don't use Firefox in android.

I reinstalled the app and the issue dissappeared, until I added the addons: - ublock origin - tampermonkey - privacy badger

so I reinstalled again, but it took several tries before the issue dissappeared this time.

when the issue was finally gone, I added only ublock origins, since this is the most important addon for me.

the issue has not reappeared yet.

I dare not update to 118.2, since this might make the issue reappear...

It will come back. This behavior is so random that I have no idea what causes. I have uBlock Origin as well and its the only add-on I use. Same thing happens. Interestingly reopening firefox it shows me exactly the page I left off on, so I just tap on play video and then it goes full screen no problem. It is extremely annoying though. I checked crash reports and there ia nothing, so it doesnt actually crush , it just exits the app. I have samsung galaxy s23 ultra. It either firefox or unlock. I'll try with 0 addons next time, it's just hard to run without ad blocker waiting for this to happen.

Okay, no idea if this helps you, but I think I've found a solution:

  1. Go into your Android Settings, then Apps, and finally App Management
  2. Select FireFox
  3. Find the "PIP" (Picture in Picture) option and disable it

I've done some rudimentary testing and I haven't had the issue repeat yet.

Hope this helps ✌️
