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.

I have a Blackview Tab16 (10" screen), which I bought last year; it was running Firefox quite happily until a couple of months ago. Now when I click on the icon, I get a sort of 'welcome' screen (with some message about a search widget?) for a fraction of a second, then FF closes and I get an error message saying 'Sorry. Firefox had a problem and crashed.' The version of FF is 126.0. I was told to try clearing the cache, but there is nothing there to clear! The tablet is running Android 12 / DoKe OS V3.0.

I have an 8" Blackview tablet which - despite needing to be plugged in to run all the time! - opens & runs Firefox perfectly happily. It's my main browser on my MacBook as well, and will run on my iPhone.

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?

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.

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.

Windows 10 pc can not start,I have gone through automatic repair and diagnostics steps,but am now on advamced options and think I need to Reset it.This will lose Firefox.When I install it again will I be able to sign into my Firefox account to retrieve bookmarks and passwords?I am very nervous about this,don't even know how to install Firefox,as someone gave me the computer and it was already in there. I am a tech dinosaur!Thank you in advance for any help.Lesley

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

When using Firefox on Android for a while, attempting to use pinch to zoom on a web site will cause Android to crash, as in the screen will go black, the G logo animation will appear, and I'll be sent back to the lock screen. It's not just the app that crashes. It doesn't seem to be a full reboot as that takes longer and starts with a different animation, but some part of Android is restarting.

It's consistent but not predictable. Pinch to zoom will work on one site fine and then crash on the same site later. It seems to be a resource issue as it's unlikely to happen on a fresh instance and it becomes more likely the longer you've been using Firefox.

This has been happening for several months, since at least July. It's happened both on my old Pixel 6 Pro and my new Pixel 9 Pro. It's happened on both Android 14 and 15.

I eventually found out I could go to Settings > About Firefox > Crashes and get some debugging info, but I don't know what to do with it. I currently have 15 crashes between now and Oct 16th which all say:

java.lang.RuntimeException: Adding window failed

Clicking Share to get more info on the latest one adds:

I don't know what to do with this info. Should I file a Bugzilla report with just this? The GUID associated with the most recent one is 7a5e5497-bb62-4e3c-94fc-5c63c51d0830. I can't look it up in crash-stats.mozilla.org. Or should I assume all crash reports are automatically received? I'd still like to be able to have a Bugzilla bug to watch for progress.

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.

Hi It is impossible to use Firefox on ios 17.2 because it continuously crash. Realle, the issue arise months ago Can you solve the issue or can you send me instructions in order to solve the issue? Regards Mario

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.

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.

Hello, I've been having issues with the Firefox app on my Android ever since the most recent update on 4th of July. Whenever I tap the "tabs" button, the tabs viewer opens as always, but if I try to scroll and browse the tab, or if I try to close any of the visible tabs, the whole app crashes. Because of that, I can only switch between tabs by swiping, but it can be annoying if you're used to using many tabs like myself. I have cleared my cache multiple times and it didn't help. I am not too tech-savvy but is there any way to fix it? Thank you!

Hello,

I have the latest version of Firefox (121.0 - 36782) on iOS 17.2 on iPad.

When I close the last remaining tab, Firefox crashes. When I open it again it asks if I would like to reopen the tab. I have been using Firefox on iPad for a while but this has been happening for several weeks. It is happening regardless of the website. It doesn't happen every time but very often.

I tried uninstalling and reinstalling Firefox. I have sync on (bookmarks and history but not open tabs).

Thanks for your help.

Firefox for Andoird crashes every time tab listing opened. If I do "about:crashes" i see the attached list of crashes ...

"java.lang.IllegalArgumentException..."

Version is 130.0 (Build 2016041319)

I tried clearing cache but it didn't help.

Frequently when I chose to close all tabs in Firefox, Firefox crashes. This happens independent of how many tabs I have open. When I close all tabs, this happens 40-50% of the time.

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?

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.
