Last time the Fire Fox updates I noticed a weird change with the browser's behavior. the browser keeps crashing just anywhere I go! I keep losing my tabs and got kicked out of the browser losing the webpages where I was! Please fix this problem and for now at the moment I would be ok if I could go back to the last old version before that happen? I appreciate your help guys!

Over the past 2 or 3 weeks, I've noticed that firefox tabs are crashing more often out of nowhere.

https://crash-stats.mozilla.org/report/index/4a42f4cd-2203-40ba-a40c-616590251210#tab-details

Here's one of the links for the most recent tab crash. Other crashes pretty much were all the same. I can't read or understand this, so I was hoping someone who can is able to tell me what is wrong.

I fear that it might be hardware related, as I've had tabs also crash on Edge and on a new install of Firefox Developer Edition (which I downloaded simply to test if things crashed there as well.) I've also noticed programs like Discord & Elgato Wave Link sometimes randomly crashing as well - but I'm unsure how to pull logs for those, Firefox was the easiest.

My laptop's hardware specs are as follows:

Lenovo Legion Pro 5 - 16IRX9 Processor: Intel Core i9-14900HX (2.2GHz) Installed RAM: 32 GB GPU: GeForce RTX 4070 Laptop GPU Windows 11

If you need more information, please let me know.

Here are some previous crashes that I've reported as well:

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

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?

TODAY'S (NEW-ish) ISSUE: - Multiple times per day I Click the Yellow button Top Left Bar to shrink and put App in dock to open again later. When I re-Large FireFox shows EMPTY FireFox Bar like I "Quit". Each time need to go to History and RE-OPEN ALL TABS??????

1. 2 within THIS text box just now, I highlighted the words: "Today's Issue" and clicked BOLD - instead it added a 2nd set of parenthesis???? WTF?

Browser is open all day. Always multiple tabs open/signed in, Paid & non-paid Apps, Email boxes, Wix, etc, many website tabs up, I do a lot of "research" - to pay my $rent and/or live my life using this "tool". Is my typical behavior. IN THE MIDDLE OF DOING WORK - I need to fix re-load Firefox again and again. . . Interrupted, distracted, observe, deal with so many Tech failures every day from ALL brands, I am struggling to keep my "life" functioning.

470+ issues/articles counted in the 11 subject boxes - in HELP section. FOUR HUNDRED-SEVENTY.

Thank you to "Volunteers" responding to help / issues!! Do you do any MENTAL help volunteering? kc

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,

J.F. Calixto Zarate

Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode. Still happens with extensions disabled (Ublock origin, Proton Pass) Started happening since Dec. 5, 2025 System is current with all Debian?Ubuntu updates installed (daily refreshes) Linux Kernel 6.8 on Lenovo Yoga i7 (ca. 2022) with Intel i5 & Intel graphics

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

I've been using Firefox all morning. Now, for some unknown reason, every time I start it up, it immediately crashes Windows. I mean, within 1 second or so. There's no time to do anything. After the fourth crash in a row, I just restarted Windows again. It was humming along happily for 10 minutes or so, and then crashed as soon as I started Firefox. After the first crash, the first thing it did was update, but that didn't fix anything. I'd love to share data with you but I'm forced to use Edge right now.

I have been having issues with Firefox since the new update. It will work for 5-10 minutes and then cashes and freezes my Macbook. I then have to restart my entire system. I have always loved using Firefox but lately its more of a pain and have been thinking of changing,

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.

For the very first time, today I got the following, "Gah. Your tab just crashed." and it now happens every time. What's up? Is this a Mozilla problem? Should I be moving on to a new browser? Help!

mozilla keeps crashing almost on every website (says the tab has crashed). I checked, mozila is up to date, all extensions removed, no viruses or spyware, and it is crashing in troubleshoot mode as well.

Also few times a day says "your device ran in to a problem and needs to restart). Please advise what to do? Here is a submitted crash reports:
