Firefox for Android Community Forum

Sometimes whenever i use twitter it will crash and stop working everytime i switch a other tab it glitches and stays on the tab i switched from, and it would also black out and make the tab unusable.

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.

For the past few weeks builds, downloading image from any website is weirdly triggering a crash of com.android.phone due to which mobile network is lost as well. Using Samsung Galaxy Note9.

I've been using Firefox on my phone for about half a year, rarely updating the browser. I did it first time approximately 2 weeks ago and since then it started to crash frequently. The latest update hasn't resolved the issue.

Setup: - galaxy S23+ - latest Android version (13) - Firefox version 121.0.1 (Build #2015995071), fd4d251332+ GV: 121.0.1-20231230165955 AS: 121.0

I have more than 100+ tabs opened with a setting activated "Close tab: Never" and "Move old tabs to inactive". Has several plugins installed: - Ghostery - Decentraleyes - Search by Image - uBlock Origin - ClearURLs

I usually visit 5-10 websites a day, having multiple opened tabs to read later. Sometimes when I open a new tab, open the page, start scrolling, the browser slows down and then crashes. It doesn't show any error, just shuts down the app so I have to open it again.

When I launch the firefox app after installing it from Google Play, it is about to start (homepage appears) but then closes immediately and returns to the home screen. Even I haven't set anything in it yet uh...

my phone details: POCO X5 5G, with MIUI EU 14 (android13), rooted

Thanks a lot.

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?

Constantly crashes with the latest 3 updates. Not sure if it's on your end or the providing web sites not knowinghow to program for Android phones.

    Too many non standard screen resolutions out there for each phone???

Guesses...???

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.

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

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.

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.

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.

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.
