Firefox Community Forum

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.

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!

I had to uninstall Firefox. I briefly added then removed an extension called "atlas speed dial". Since then, I haven't been able to get a tab to open. I uninstalled and reinstalled Firefox. It recognized that Firefox was on my pc before when it reinstalled. I had some tabs open and organized. I tried to recover tabs. I tried just using a new window and opening new tabs. Finally I just uninstalled for good, unless someone can tell me how to fix this issue. I'm using two other browsers. Luckily, when I installed another browser I'm using, I decided to temporarily set the new one as my default. I've setup several shortcuts and organized my desktop since then. So all of the shortcuts work through the other browser. But, I'd really like to still be able to use Firefox and especially would like to restore my open tab organization.

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!!!

Here is the current situation.

Firefox is consistently crashing in Windows 11, either a tab crash or the application itself. I'm not sure how to resolve it at this point. It was sufficiently bad that at first I assumed this was a problem with my Windows 11 installation, and did a complete reinstall of the OS followed by a fresh install of Firefox.

That did not resolve the problem. Firefox is still crashing.

I completely replaced the SSD assuming there was some kind of read/write problem between it and Firefox, did a clean install of Win11 and Firefox, and instead of porting my profile ported only my bookmarks and passwords into a new profile.

It's still happening. I don't know what to do at this point.

Hola, firefox no funcionaba bien, busque que hacer y lei de enviar los id de informes de fallos, pero como eran muchos los elimine SIN ENVIARLOS, porque no sabia que estaba enviando y ahora no logro poder usar Firefox, lo desinstale e instale nuevamente y todo sigue igual. No se como solucionarlo, necesito ayuda por favor.

I'm in Troubleshoot mode, no extensions running, and tabs are crashing again. Here are crash report #s for today:

bp-68a25ce5-25e5-486f-8ac7-b1c440251204 bp-44d835db-c6b3-4fda-bc0a-2b3fd0251204 bp-456fdf26-e4ca-4994-a1a8-4fd960251204 bp-fd926c51-7db6-47b8-be27-28b340251204 bp-55c9f898-ec6a-4f5e-85d2-252900251204 bp-991e08b6-ff21-44e3-8cd3-2293a0251204 bp-3929ad82-3fed-439e-9877-1859e0251204

Is it coincidence that this is happening on my Windows 10 machine since MS support for Win10 officially stopped? Gosh, I just don't know! grar grar grar

Every time I attempt to open any tab on my laptop computer I get the following message.

Gah. Your tab just crashed. We can help! Choose Restore this Tab to reload the page.

(Two buttons)

Close Tab Restore This Tab

Unable to restore tab. It is impossible to use the Firefox with this upgrade. Looks like I need to find another browser.

I have been using Google Messages in Firefox for over a year, and have never had any problem until the most recent Firefox update from Linux Mint. Google Messages loads on the tab, and everything seems fine. But when I click on a conversation on the left, it crashes as it's loading the conversation.

All of my software is up to date, i.e., no new software updates are indicated in the system tray (?) on the panel. Firefox info: mint-001 - 1.0 147.0.2 (64-bit)

System info: Linux Technodrome 6.8.0-100-generic #100-Ubuntu SMP PREEMPT_DYNAMIC Tue Jan 13 16:40:06 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux

 Host: Technodrome Kernel: 6.8.0-100-generic arch: x86_64 bits: 64

Hopefully this gets fixed soon, because checking my messages using my PC saves so much time.

Thank you

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)

Since around version 96 it seemed some new core changes made to how ff operates. any one care to share what the "big changes" were around that version rollout tldr?

since ver 96 ff became secondary browser. Using to test/isolate issues w/chromium (sigh). Now since ver 132 profile manager opens browser for correct profile everything looks good then 20seconds later ff crashes eorror: Exiting due to channel error

Inspiringly i see this forum is being used still so thought i would see if anyone has ideas what changes btwn ver 96/101 and 132 which may cause this new issue, maybe i can backout the changes and get back to using ff as a secondary backup again ....

IDK about anyone else but i LOOOOONG for the ole days when ff was a daily driver option on linux

Firefox crashes all the time. Sometimes it makes me manually shut it down with a one-click dialogue box. Other times, it's a two click dialogue box where I click "close firefox" and then have to click again to close the box. This doesn't seem to change performance, but it's a bother. Is there a way for me to fix this?

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,

For whatever reason every time 'Firefox' browser goes down my email shuts down also. This did not happen prior to trashcan Win!!(recently installed). It's a pain in the ass having to reactivate 'Firefox' then contact my email server to reactivate my email service. Any assist is appreciated. TangoYankee in advance.

Hello. The browser will start fine and run for most of the day. I haven't made any known changes to the PC. At some point the browser will crash for all tabs and all windows. Any attempt to refresh goes to the screen as seen in the attached image. The "Restore This Tab" button does not work. I have to close all Firefox windows. Then the browser will work again.

I'm using an Alien computer. Windows 11. Everything is up to date. Firefox version 145.0.2 (64-bit)

Thank you.

I tried several things, but nothing helped so far. I did an offline-scan with Windows Defender, I opened FF in troubleshoot mode, cleared cache etc. I got the following crash-ID:

bp-7a77a8ad-7637-4fba-bd20-9e4730251209

Maybe someone here is able to help me. Thanks in advance.

For the last two days, I have been ubable to access settings (X,). When I click the settings cog in th toolbar, thr toolbar grays out. I have also tried to access settings using the Hamburger Menu, clicking on settings, with the same result. I have clicked on Firefox in the menu tab, same result.

I have closed and restarted Firefox, with the same result.

Additionally, I can only close Firefox by force quitting. I don't know if the two are connected.

TIA. Keith

Recently i have a issue on firefox that it has been crashing without any warning or signs and these crashes are absolutely random no pattern upto my pov. IDK whats the issue

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?

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?
