I have read the thread for this similar problems, tried all the suggestions but I'm Still experiencing videos not staying full-screen. Is there any other solution to it? This has started since yesterday but everything was fine before then.

I'm having the same issue as previously posted below. I am on a Google pixel 7 pro.

"On youtube mobile site or a reddit video, when I click the bottom right button to fullscreen the video, a message pops up that says 'entering fullscreen mode' (with a firefox logo on the left of the message) and then firefox closes and I'm at my android home page

This seems to happen when I watch videos in a new instance. If I reopen firefox to the video and then try fullscreen again, it goes full screen no problem. So basically it's annoying and happens when I try to watch any video full screen for the first time.

Is this a known bug? Wasn't an issue on my old phone (I just got the galaxy s23). "

On YouTube the video will start playing but the rectangle it should be in will still be black, refreshing usually works. Sometimes a video will simply stop playing. Sometimes i have to close all apps and restart the browser twice to get it to work. Sometimes trying to go to full screen will crash the app. Sometimes popping the app out of full screen into a floating window crashes it. This one is new, it's the uploaded screenshot, it crashed mid video and made the video look funny.

Steps to reproduce : - go to YouTube - open a video - press the full screen button or tilt the phone sideways to trigger full screen - Firefox crashes and forces back to home screen - if opening Firefox again only half of the video component shows as in portrait mode, rest is black screen - if attempting to go side/full screen does properly show the video, but going back again to normal screen still shows the half black screen

I can reproduce this with a almost 100% rate, it only fixes itself by restarting Firefox, where it will work until phone is put to sleep mode.

I tried reinstalling Firefox from scratch, as well as deleting my browser cache and it didn't fix.

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.

Hello,

I am getting a frequent freeze in the Android app and then shortly after a crash. Info: - happens on FF, FF Beta, and FF Nightly,and reinstall/phone reset didn't fix. - Samsung Galaxy SM-G965U running Android 10. - every error starts with java.lang.OutofMemoryError. - it never happens just on startup, just on auto fill, or some of the similar crash reports I've seen around here. - it does appear to be site-specific, but sometimes the site works and sometimes it does not: if I close the last tab after a crash, it will usually work for awhile. - Sync and disabling Add-ons doesnt fix it, although perhaps its worse with uBlock Origin enabled (not conclusively)

Thanks for any suggestions.

Android System UI crashes after a download completes in Firefox for Android.

About a week ago my phone (Sony Xperia ZX2 Premium running Android 10) started 'crashing to the lock screen' whenever a download finished in the mobile version of Firefox. If multiple files are downloaded in short succession a popup will appear informing me that the 'System UI keeps stopping', with a prompt to close the app or to get to the app info (see the attached photo - clicking either option sends me back to the lockscreen, with the only difference being that after unlocking the phone the former will have stayed with Firefox in focus, and the latter having opened the Settings app on the System UI entry).

Going to about:crashes shows no recent crashes on Firefox's ends. (Plus, Firefox shows no signs of having been closed [like tabs being reloaded] after unlocking the phone again post-crash). The issue currently only happens when downloading a file through Firefox; downloading a file through Edge, Discord, or the Google Drive app produces no problems.

I have already tried force-stopping and restarting Firefox, restarting the phone, and clearing the download history with no luck. Furthermore, I have also checked for updates for the system, the Google Play Store, and Firefox for Android, however all of them were already up to date.

Any help would be sincerely appreciated.

Dear Mozilla support,

For a while I have the problem that when I want to watch a video fullscreen on a website e.g. youtube, inline video etc. Firefox stops and completely closes. This is only the first time when I play the video. When I re-open the browser I can continue watching the video fullscreen without any problem. I don't receive any error messages.

Attached the specs of my phone and Firefox browser.

Kind regards, Rick

When attempting to enter full screen mode on Firefox for Android, and to get into landscape mode, the browser appears to crash, keeps audio playing, and "entering full screen mode" dialogue pops up. Have to open Firefox again, and can only be viewed in landscape mode while session is continued. To return to non-landscape mode, the app needs to be force stopped, otherwise you only get to see the left one third side of any web page you navigate to. Seems to have started with most recent update. Is there any way to fix?

Hi,

Since I've installed the latest Samsung OneUI6/Android 14, Firefox keeps crashing randomly. There was a firefox update after (120.1.0, build #2015989146), but same behavior. When opening accessing a new url (either new tab or existing tab). No message displayed, simply closes. Everything is up to date, non rooted galaxy S23 ultra with Android 14/OneUI 6. Already cleared firefox app cache, uninstalled and reinstalled (this worked for a few hours, but it's back to same behavior).

Any ideas?

Just updated to latest version of Firefox for Android (ver 113). When I try to watch a YouTube video in full screen, the app suddenly closes, as if I pressed the home button (note: I say "close" rather than "crash" because when I reopen it, all the pages are still loaded). This doesn't happen every time, but it is annoying. Is there any way to fix this?

Hello!

Firefox for Android consistently closes whenever I try to play a video in full screen mode.

The steps to replicate this bug are as follows: I go to a website that has a video (like YouTube), I start playing a video, and then I click on the full screen button. Firefox then closes out to the main menu of the home. When I try to reenter the app, the Firefox app becomes a black screen with a horribly offset tiny corner showing a portion of the webpage.


I cannot find any crash reports in the "about Firefox" subsection of the settings

I am using The latest version of Android 13 And my version of Firefox is 114.2.0 (Build #2015957435). I have tried clearing the app cache, and reinstalling the app. Neither fixes it.

Please let me know if I can provide anything further!

Does anyone have any recommended fixes?
