Firefox for Android Support Forum

Hi,

We use about ten Android tablets running Firefox in our shop for our employees to enter on a webpage daily some informations. Tablets are programmed to keep display active 24h/7d, firefox is pinned so the app stay opened and users don't go to other app. The extension LeechBlock NG prevent users from accessing other webistes. Everything work well except on mondays morning.

Without fault first person to try to connect on the website will see the app crash to the desktop. Since the app is pinned user will have to wait for a supervisor to come in and unpin the crashed (and invisible) app, re-launch it and pin it. Then it will work all week without issue as long as the tablet is used at least once a day. We recently added a new tablet which is used less than others and that one does crash during the week but never twice in same day. Here's the crash report that we have (I checked multiples tablets and they all share the same crash code):

Wondering if someone can help me decypher this to fix/prevent it. Is it the extension or browser itself that cause the crash if the page hasn't changed long enough? Thanks for suggestions (I will not consider "have you tried without the extension" as a valid suggestion)

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.

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.

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.

When I want to watch a video on fullscreen on my Samsung tablet, Firefox minimalizes throws me to my homescreen. After I go back to Firefox, the video is choppy and has a low fps. I fix it by forward and rewind the video by clicking on the side of the screen. Very annoying. Browser is up to date, please help

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.

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)

Firefox Android just crashed when opening a bunch of bookmarks and then again every time I wanted to report a crash. I hope someone here can forward this to whoever usually receives the crash reports.

All video players on websites will, if viewed in full screen, close the firefox app on my android device. The app gets minimized and can be opened back, but all pages become bugged then and appear in half the page only, links cannot be copied either, the page will only work partially when my phone is held horizontally. This issue happens with or without auto-rotate enabled. The bug most often happens as soon as I set a video on full-screen, but can happen while the video is playing also. I tried disabling all of my add-ons and the bug still persists(I will attach a photo of my addon list). Here is a video of the bug after the app closed and I reopened it.

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.

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.

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.

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.

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.

Hi support team,

I was using Mozilla Firefox on my Samsung Galaxy s20+ without any issues. I have transferred all data from my old one to new one, Samsung Galaxy S24 after this migration Mozilla Firefox crashes, when I was forwarded from an app.

Standard browser: Mozilla Firefox I have already reinstalled the Mozilla. This action works properly with other browsers.

Kind regards Mustafa

Dear Concern, Suddenly I Found Crashing Problem In Fire Fox New Updated Version. When I Try to Save Any Image Or Download Any File From it’s show A Crashing Problem. I attached A Photo Of This Crashing Problem. Sir Please Fix The Problem As Soon As Possible. Thank You.

I am posting this issue at the request of E from Firefox's app developer feedback after I submitted an app review.

The app continues to be unstable on my Pixel 6a (latest OS, Android 13) after freezing up on what appears to be any heavily scrolled pages or those that create a heavy cache. This freezing then causes abrupt phone restarts shortly thereafter, but not always immediately. Usually the culprit seems to be linked to Facebook album viewing, Imgur albums with article-length descriptions, etc. The abrupt phone restarting occurs whether force stopping Firefox and clearing the cache right away or not (although the restarts seem to happen faster if I force stop the app). I have simply closed the app during the freeze, put my phone down, and come back minutes or hours later to it having restarted on its own.

In addition, open tabs have a tendency to lose their scroll spots on a non-infinitely-scrolling page (e.g. an article not requiring expanding) when the app is minimized but not closed. This is probably unrelated(?) and isn't as critical as the spontaneous restarts, however.

It looks like many Pixel 6a users have had this issue, although those support threads from 8-9 months ago have now been archived. Someone else mentioned scripts from the websites themselves may be to blame? Would be curious to hear of any specific fixes. Thanks!
