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

Not exactly sure what update started this but it worked fine before. I use Firefox on s23 ultra and tab S8 ultra. Both are signed into and I've tried to reinstall the app but still doesn't fix the problem. If I go on YouTube or a website that has video, if I click on full screen the app closes down but keeps playing the video. If I open the app and hit full screen again it then works and fills the screen with the video. If I could go back to a month ago maybe since this is pretty new bug. I do have add-ons but even with a clean install and no add-ons it still does the same thing. Was referred here from the play store.

Recently I migrated to Firefox to get rid of the unbearable heavy load of ads on Chrome and would be satisfied with such change if it was not by the slow way Firefox handles Youtube player. As I touch to maximize the screen it is a painful process : the image rotates to a smaller rectangle and after some seconds finally fills up the screen. Once in full screen video player control no longer works. The same did not occur with Chrome , in full screen I used to have control. I noticed previously on my desktop running Windows 10 that Fireworks it is much slower to go full screen on Youtube and to exit full screen. I think Firefox handles with more difficulty the Youtube player than Chrome , or perhaps I am missing something. Unfortunately I think I will have to return to Chrome on Android.

YouTube soft-crashes when going full screen sideways

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.

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). "

To be really homest, I never had this kin of problem in chrome, your youtube video player has too many bugs. The issues I've faced are: 1.Whenever I play a video, it is always choppy which is so frustrating. 2.This happened so many times, when I turn switch into full screen mode the whole app crashes.

Please look into this issue, I like the UI and that is the reason why I'm still using mozrilla on my phone.

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?

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.

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.


OS: Calyx OS 4.12 HW: FairPhone 4 Firefox: Fennec v116, Firefox Nightly Add-ons: uBlock Origin, Tampermonkey

My pixel 5 still has the bug that Mozilla claims they fixed where if you rotate the screen of a video to landscape then it will send the app to the background or will not fully rotate and more the half the screen will be cut off. Will this ever be addressed? It's been months now.

The only 'fix' seems clicking on the app and sending it to the background over and over.
