I-Firefox Community Forum

I tried to purchase something on Amazon. When trying to log into my Amazon account it asks to perform 2Fa on my mobile or use a pass key. But neither option responds and Firefox is completely locked up - cannot tab, select menu options etc. I have to use the Apple Mac Force Quit screen to kill it. But when I open Firefox again, the same tabs appear and it's still locked up on the Amazon screen. Cannot use Firefox at all now, forced to use Chrome. How can you reset FF. so that it just opens a new screen?

There is a common error documented in https://support.mozilla.org/en-US/kb/firefox-already-running-not-responding but none of the solutions fix my problem.

I have signed out of my PC and mobile devices Done a complete uninstall of firefox on the Windows 11 machine Searched and removed ALL files on the drive associated with Firefox or Mozilla, including cache and temp Searched and removed ALL Firefox or Mozilla keys in the registry Checkdisk Used update to refresh the windows install Multiple reboots

and a fresh download and install of Firefox. And still get the "already running" error. If I wait long enough - several minutes - I will get the "crash report" screen as the background process finally ends.

Any suggestions?

Since the last update I’m able to login to my banking websites but there are certain functions when I’m not able to do. Specifically I am unable to open the particular page that allows me to view my previous bank statements and download them. I get a crash problem each time. I bank with Navy Federal credit Union. And One AZ credit union I was able to access these pages using Google Chrome. I am submitting this through my phone browser because using the PC browser will not open your feedback pages. I get a page crash with that also.

Hello dear Mozilla team,

It has come to my attention that it is the second time, that Firefox randomly restarts (crashes?) and as an consequence of it Loose all of my tab groups, which are really help-full to separate work and projects at work.

Is there something known about this behavior ?

Just to know if it is known why this happens. Or what should I keep in thoughts to prevent it....

Many thanks in advance.

Kind regards,

This version is crashing its tabs and the program and often the entire windows system. It is the worst version ever made. Did you even beta test it? When will it be fixed?

HI Since the last update from Firefox. I am experiencing frequent and multiple crashes. so much so I have beenusing google chrome as alternative browser. It would appear to me that the "new" version is unstable. = Version 147.0.4 (64bit).

Do I go back the the previous version? and if so where is it.

Pete

Using Ubuntu 24.04.3 LTS with Firefox 147.0.3 (64-bit)

Firefox crashes when trying to access any banking website. Can get to the login page, but then firefox crashes and a crash report window comes up with quit or restart option. This has been going on since shortly after upgrading from 22.04 Ubuntu. Started with Firefox 147.0.1 and after upgrading to 147.0.3 did not fix the issue.

Started Firefox in Troubleshoot Mode and that works when going to the bank login page. Using Standard Theme and only extensions Windscribe - Free Proxy and Ad Blocker and DuckDuckGo. Disabled both and same result of crashing om bank log in pages.

I run Windscribe VPN through my separate subscription, but it doesn't matter if it is on or not. Banking websites (Keybank, Kinecta, Capital Group) still crash Firefox

Also crashes when trying to access Excellus BCBS log in page. Most other websites (news, sports, Amazon) are fine.

Searches on your support page yields ) results.

Please advise!!!

Windows10 simply multiplies the numbers of active Mozilla Firefox Apps which are open. Every day for about two weeks I've been having to delete hundreds of Firefox Apps open in the Task Manager. So many open in a very short time it locks up the Win10 system. I've attached a pic

Win10 will no longer let me download & transmit a .jpg file, sorry

Watching a CNN video on YouTube Firefox suddenly freezes and does not accept any further actions. Even shutting down it will block the process and I need to use the "Shut down anyway" function. Similarly, Thunderbird will lock up in the middle of writing a response, but here it is just the window and I lose what I typed, but I can go back and push "reply" again and retype the answer. Whether these are down to similar issues I don't know. Obviously, this sounds like a graphics driver, so I made sure all updates are installed and there is no further update available for both, Firefox and Thunderbird as well as the system drivers.

Any pointer is appreciated as this is really annoying. Thanks

I have recently started getting the message "Gah Your tab just crashed" when using firefox W11 lenovo laptop Up to date with updates Started yesterday (26/2) Happens most of the time now Seem OK on another laptop

Since the latest Firefox latest update yesterday (02/24/2026), each time I try to open a new tab in Firefox it crashes. I get a "gah, your tab has crashed" message but when I hit the "restore" link nothing happens. How do I fix this at my end? Thank you.

Why does Firefox Desktop now completely crash every time I press the Ctrl and cursor keys whilst navigating through text?!!! Very frustrating and I've had to abandon using your app completely. Please fix and redeploy your app as a matter of extreme urgency!!! thanks

this feature absolutely DOES NOT WORK on ANY Firefox desktop browser on MULTIPLE machines I have tried - and actually I'm pretty sure I can say the same thing about the ANDROID app too?

I can confirm EVERY SITE I have trouble signing in using Passkey on Firefox I can SUCCESSFULLY sign into on Chrome - every single time - the issue is clearly the BROWSER

worse still, it often COMPLETELY CRASHES Firefox and I have to forcibly KILL the process and restart Firefox, after even ATTEMPTING to use this feature

I have tried it on M1 Macbook Pros, on Ubuntu desktops (24.04 LTS) and also on Android

right now I am typing this in on a Firefox I literally just had to Force Quit and restart on a Mac - build 147.0.2 (aarch64)

A bit over a month ago, I was away from home for several weeks. When I came back, a browser that worked perfectly before became near unusable with constant and random crashes. Sometimes they occur even with no user input. I have tried troubleshooting mode, I have removed all extensions, I have tried all the fixes I found on Google, I have reinstalled the browser, I have updated all the drivers, I have done MemTest86 which was passed with flying colours and I have even installed a firefox fork (waterfox) to try and fix this all to no avail. I have no clue where to go from here, as it feels very bizarre. All help is much appreciated.

Hi.

This inquiry is related to Mozilla Firefox web browser from version 140 until 148 for Windows 10 64-bit operating system. Over the years I have rarely updated this type of Firefox web browser, but in the past two or three years I get too many crashes. Some of the crash logs or reports are saved, but nothing else is wrong with the web browser other than random crashes. Now I have the latest 32-bit version installed. Should I use 64-bit instead? But now It has become very annoying. I have maximum ten to fiftheen tabs open at the same time in the web browser, but I never understand anything for why it crashes so often.

My firefox tabs have been constantly crashing over the last couple days. When I tried to diagnose issues in troubleshoot mode, they still kept crashing. Here are the most recent report IDs for the crashes: bp-06b1b48f-9213-4497-8398-a11890260130 bp-726d0348-6100-41cb-a298-909550260130 bp-ce8a6448-fcb1-4543-9ed4-275b50260130 bp-2c16e522-cd5f-4b9d-bb1e-6f18e0260130 bp-80520225-49fd-4f46-8453-58b300260130 bp-6c4bd533-ac96-44f0-9593-81ddc0260130 bp-a9573328-6e28-41d5-bd1e-91cf30260130 bp-3992c4d8-2a09-4fc4-a426-016b50260130 bp-2c7e318f-e080-4e56-84ee-63a030260130 bp-986e724b-2356-4790-9dc9-3687f0260130 bp-ae6ac0bd-b096-4212-8252-d55440260130 bp-4c8705f9-4529-405a-9d09-967b70260130 bp-a90c5596-f9cd-4d63-8fd6-a55c70260130 bp-fdf29d55-6cd9-450c-a552-7cca80260130 bp-519e5b29-a47b-4c65-bfda-c1f970260130 bp-fad47bb5-3880-4090-bdb7-b754e0260130

Any help would be appreciated!
