I-Firefox ye-Android Isithangami Sokwesekwa

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

Once a while Firefox would freeze up and when that happens it would without fail reboots the phone if the phone goes to sleep and if I don't force close the app quickly. It might've done so anyway without putting it to sleep but I haven't tested leaving the screen on long enough. I noticed that if I was quick enough and force stop the app the phone doesn't reboot, but that window is really short. Maybe 2 seconds or so. Suffice to say force stopping didn't always work since the window is so short. When Firefox freezes other apps and phone functions work normally. It's been ongoing for a while through multiple updates. I see some people have already reported this same issue here. Can Mozilla fix this please? I have uBlock origin addon installed thanks. Also this never happened with my Pixel 3 phone which I was using up until a few months back so maybe it's pixel 6a specific. Alot of people have this same issue with pxiel6a from googling. It can freeze on any site I visit but one example is reddit.

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.

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.

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.

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.

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?

I used to have loads of inactive tabs and usually around 9-10 active taps and sometimes 30 tabs in total and it was all good.

Start with (I think) version 109 it when I have around 9-10 tabs (no inactive) the firefox automatically closes itself right after I start it.

Doesn't leave me any chance to even close tabs or do anything.

I tried: force stop then clear cache and still happens.

If on top of those above I also do clear recent apps, it might work.

I noticed it would work if it doesn't have the thumbnails of tabs which might imply that when it doesn't have other tabs cached it works fine.

For months now, Firefox Mobile has constantly been getting "app has stopped responding" crashes and even hard crashes (multiple times per day) for Pixel users. There's already a bug report about it but the FF team's response is that they aren't going to do anything. They claim it's an issue with the kernel but no other apps / browsers on the Pixel have this problem.

This is beyond pathetic. Maybe this not-my-problem mentality is why Firefox has reduced to less than 1% penetration.

When using android 12 Firefox on Nokia g60 the browser hangs and locks up phone. Does not happen immediately but after a few mins. https://standingstones.org/viewer.html?tour=-1

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?

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.

So on my main firefox account the app crashes after a few mins consistently, on my phone and Tablet.

However I recently made a different account using a different email adress and zero crashes.

Is it likely to be a settings issue?

Going to full screen on YouTube (and other video websites) usually breaks the Firefox app on pixel 7 pro. It keeps playing but just closes and can't be reopened. I have to stop the app, open it again, and try again. Does anyone know how to fix this?

When reading the site https://hellasjournal.com after a while Firefox freezes and crashes. It's not a site problem because with Chrome works fine.
