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!

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.

My Firefox on my iPad alsways crashes when I try to select a synched tabs from another Firefox on a different device. The tabs from the other devices show up and the sync is always up to date, but the windows does not react on any interaction, instead the Browser crashes after about 1 minute of inresponsiveness and returns to the home screen of my iPad. I already discenneted and reconnected the Firefox account used for sync on this browser, it did not help. I use the same Firefox version on my iPhone and that does not have this issues, selecting tabs from other devices works as intended.

Firefox version: 114.3 (31916) iPad OS: 16.5.1 (did not work in iPadOS 16.5. either)

Firefox on iOS crashed when I toggles the inactive tabs button on and off and I had about 48 tabs as well 300 + private tabs open for years and when I clicked on the restore tabs button, it did not work and nothing came back. Can you please help me restore the session? I really need those private tabs back so I can save them accordingly. The history is there for the normal tabs but the private ones are the ones I really need back. I just need to be able to restore that session. I can provide log files as needed. I would really appreciate it. Thank you.

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)

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.

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?

P

1. Open the Firefox for Android application 2. Either browse around first, download something beforehand, or do it right at the start, go to the 'three dot' menu on the top right screen and select the 'Downloads' section. 3. The application will freeze without opening the section and after a while will say 'Firefox not responding' before crashing.

Out of nowhere, the browser stopped when I was browsing and the pages started showing slowness. 👇🏻👇🏻👇🏻

Youtube won't work anymore. I've been watching youtube for years and now on Firefox and now it won't work anymore. For months now it keeps saying "Gah. Your tab just crashed". I've tried many things to fix but nothing works. Really annoying. Is it time for me to stop using firefox?

Thanks

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.

Hello everyone,

I'm encountering a persistent problem with my website when accessed via Firefox for iOS. The issue seems to be causing frequent crashes or instability when users attempt to navigate certain pages or perform specific actions.

Here are the details of the problem:

Browser: Firefox for iOS Devices tested: iPhone X, iPhone 11, iPad Air 4th Gen Issue: The website crashes intermittently when users perform actions like [specific actions causing crashes, e.g., filling out forms, clicking certain buttons, loading specific pages]. Frequency: The crashes occur frequently enough to hinder the user experience, impacting our site's usability. I have checked the website on other browsers and devices, and it seems to function correctly without any crashes. This leads me to believe that there might be an issue specific to Firefox for iOS.

I've ensured that the website's code is compliant with web standards and optimized for various browsers. However, I'm unsure why this problem persists solely on Firefox for iOS.

I'm reaching out to the community to seek advice, suggestions, or any similar experiences you might have encountered. I'm open to debugging suggestions, potential workarounds, or any insights that could help resolve this issue and provide a smoother experience for Firefox for iOS users.

Thank you in advance for your time and assistance. Your input would be greatly appreciated.

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

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)

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 had about 500 tabs on FF on my iphone open. The browser crashed and now all of those seem to be gone. "Recently Closed" is empty. Starting the browser just opens an empty page. I had sync turned one but oh magic the synced tabs pretty much immediately diappeared from the other devices as well. Any ideas how I might be able to recover those tabs? Could they still be saved somewhere on the iphone or in the cloud?

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!

Hello, I have had issues with multiple crashes with Firefox for I Os, now when I try to access my xfinity email, I get the to and from but not the body of the email. I updated Firefox and rebooted my iPhone but still the same results.
