Firefox for Android Support Forum

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

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.

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.

Poco F2 Pro is hard crashing requiring device reboot, starting maybe a week ago, and has happened three times. I don't know if it's hardware related but I've not seen the behaviour in other apps. I'm not using beta version.

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.

After updating Firefox for Android, my phone started rebooting after downloading any file. This makes it very difficult to use the browser and I had to use Chrome temporarily. The Crashes tab in About Firefox is empty. I tried to collect a logcat and uploaded it to Google Drive (maybe this will help somehow.): https://drive.google.com/file/d/1kmdS5rTH3r0u09KLxeUDeY5U8r5xiEK1/view?usp=sharing. I hope this information is helpful in solving the problem.

Whenever i have tried downloading anything from firefox, it crashes the system and the boot logo appears. These crashes also take a lot of time to recover from. My phone is vivo s1 pro and its running android 12.

I have just installed CCleaner on my Android phone. Immediately having installed it and run an initial clean, my phone shows a repeated error message "Firefox keeps stopping". If I try to open Firefox it shuts back down within seconds. I have tried uninstalling and reinstalling Firefox but the same issue recurs. Is there a known issue with Firefox and CCleaner on Android? I can see nothing on the CCleaner support pages.

firefox is crashing when i try to download some file. I gotta clear the app's data for it to work normally again, but this always happens when I try to download it again, also, the browser doesn't open after it crashes, only after I clear its data.

Firefox for Android version 119.0.1 Android 11 (64 bits)

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

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.

So I have a lot of inactive tabs open on my mobile device Samsung Galaxy S21 (I do not know and can't find out how many exactly); and I want to be able to have a "backup" of them so to speak, or be able to save and transfer them somehow as a file locally on my phone or a folder on my desktop through the sync function, if possible. But I believe I'm running into issues because the sheer number of them is too large?

Here's the thing though, I already did this with my tablet's (Samsung Tab S7) Firefox browser app, and since it had fewer inactive tabs, I was successful in sharing their data into a Samsung Notes file and saving that as a PDF on the tablet! So this seems like a reasonable solution (I think? but please let me know if I'm wrong about that).

So far, the Firefox app on my phone has crashed every time I've attempted this. I was using the "share all tabs" function from the tab settings menu and no matter what method of saving the info I chose (i.e. saving them to a Notes file, as a PDF directly, upload to a cloud storage, or printing it even...), the app froze momentarily and then quit, not allowing for the backup of the data.

I understand that the file size is probably too large but there is no other option for only doing the "sharing"/saving in smaller sections or chunks either. So, I would appreciate any help you can offer me in how I can fix this, deal with the process, or pointing in the right direction of some other method that would help me achieve the same goal!! :)

Thank you so much in advance, hope you are having a fun & lovely October day/night!

(oh btw, P.S. I thought I'd attach the crash logs of both my phone's own reports for the app AND the crash logs you can access in the Firefox app as screenshots in case that's helpful ^_^ and of course I'm also going to leave the Socorro link for the specific most recent crash related to these issue down below this paragraph! Hope that's useful somewhat!!)

I raised this issue in my review on the Google App Store and was asked to submit it as a question here. On my phone (Oppo running on ColorOS 13.1), Firefox will stop working a number of times a month. For about 24 hours, aside from Google result pages, nothing will load, and I'll be stuck looking at an empty loading screen. The last time I raised this issue I was told to delete and reinstall the app, which worked in the moment but did nothing to stop the problem occurring again. Aside from waiting for the app to fix itself, nothing I've found works.

Hi!

I found an issue in Firefox for Android. I recreated it in stable 118.1 and nightly 120 on two devices (Samsung S21 and Xiaomi Pad 5).

To reproduce the issue:

   Open Google Drive or OneDrive (I didn't check on other clouds) in desktop site mode.
   Try to upload a file of size ~1GB.

In 70% of cases, Firefox will crash in different ways

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?

while performing a download, "com.android.phone has stopped" apears, the signal strenght indicator in the upper right restarts(disappears, reappears with the 4G mark, the mark disappears and the indicator works after), after that the phone service and the phone app work normally. the download finishes normally.

using motorola e7 plus, android 10

tried restarting the phone, deleting cash and data of phone app, deleting cash of firefox

tried downloading using google chrome, all work normally.

it is possible that the issue started happening after I updated firefox but It's possible that it was happening before too.

I recently moved to a new phone, Samsung S23+ after being on a OnePlus phone for several years. My new phone is much beefier but has been suffering from frequent crashes (it actually just crashed as I was typing this part.)

The crashes all seem to be variations of:

284caa59-49ff-4df4-ae44-17afa3c49fa4 java.lang.OutOfMemoryError: Failed to allocate a 16 byte allocation with 1502304 free bytes and 1467KB until OOM, target footprint 268435456, growth limit 268435456; giving up on allocation because <1% of heap free after GC.

I've tried the beta version of Firefox android, I've tried with and without add-ons, I'm not sure what else to try.

Something that I noticed and thought might be related is that I had 4.7GB of background mobile data usage over the past month. I tried turning off background data usage, but it is still crashing.

when i am downloading something my phone restarts even if i re install the app it still restart. I tried downloading at Chrome and my phone doesn't restart only at firefox restart my phone can you please fix this as soon as possible i need to download stuff here for my module thank you..

Very often when clicming the adress bar (almost always on sites like old.reddit.com, the app just stops responding and I must reopen it. I'd like a solution that won't involve removing all my bookmarks, history and saved data.
