my firefox keep crashing when i join google meet and i need to do multitask so i open another firefox windows(private or not) it always crash few second after, i have tried the trouble shoot mode its still crashing, even the new windows from SSO request do trigger my firefox to crash. when the browser crash it does offer me to restore my session

Hi, The versions of Firefox since Feb 2026 have been extremely memory hungry on Windows 10, even though I have the option to restore tabs on demand set to TRUE in the config.

The memory hungriness has got so bad now that even on my 16GB machine, about once a week I find that my computer has suddenly run out of memory without warning and my entire screen goes black (not just within the Firefox window, the entire screen). When the computer gets into that state I am unable to use Ctrl+Alt+Del to get back to Task Manager, and the only way out is to hard-reset my computer.

This means that whenever I want to do anything else remotely memory hungry, such as running my research code, or a game, or a Zoom meeting, I have to kill Firefox first. But I sometimes even end up with black screen when trying to use Word or Excel alongside Firefox.

Essentially, Firefox is becoming unusable on my desktop, and its bookmark feature is borderline unusable on mobile now since the update a month ago made it impossible to change which folder I save my new mobile bookmarks in.

So if I have two more black screen clashes I think I will give up using Firefox entirely after being loyal to it for about 15 years. This is extremely disappointing.

1 stop popping up stuff everytime i open firefox, thats why i left google in the first place

2 shut up about ai no human with an actual brain cares

3 fix the memory leak that has been a problem for maybe a little over a year now, no extensions installed firefox crashes on a regular basis when not in focus.

Fix these things and ill come back. Till then, im done downloading firefox for my systems and my customers. Its unstable and unusable... In a time where theres barely any other option.

Youre pissing your userbase off.

Sincerely,

Disappointed.

I have just reinstalled Windows 10 and now I cannot see my old firex=ox history from prior to the reinstall of Windows 10 Is there a solution and also i downloaded firefox and now every tab crashes immediately

Just got my repaired laptop back. Windows Home 23H2 build 22631.6199. Installed Firefox, synched my account. Firefox or a firefox tab have crashed 19 times in the last 3 days since the fresh install.

Actually crashed while preparing this message. What to do?

I had an issue where my browser disappeared. Here are specifics for my installation.

Name Firefox Version 142.0.1 Build ID 20250827004350 Distribution ID raspberrypios User Agent Mozilla/5.0 (X11; Linux x86_64; rv:142.0) Gecko/20100101 Firefox/142.0 OS Linux 6.12.62+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.62-1+rpt1~bookworm (2026-01-19)

I relaunched and then restored previous session. After that, I searched open tabs, but when I selected a tab that was reported to be opened,  it was not restored. I went to troubleshooting mode and it worked fine suggesting some issue with an extension.  What, if any logs could I capture to help debug? thanks

Hello everyone,

yesterday I got quite a scare. While Firefox was open, a new tab briefly appeared showing the page about:processes, and immediately afterwards the browser closed itself on its own.

At the same time, Chrome was open in the background. When I clicked on Chrome, a prompt appeared asking whether I wanted to allow changes to be made to the system (the typical UAC prompt). However, I’m not entirely sure if this was actually triggered by Chrome or possibly by another application.

I clicked “No” on the UAC prompt and immediately unplugged my keyboard. I recently started using an ASUS ROG Falcata, which is connected via USB.

After that, I ran a virus scan with Windows Defender — it didn’t find anything. I also ran AdwCleaner, which also came up clean.

At first, I suspected the ASUS ROG Falcata (I’ve only been using it for a few days), since it’s almost like a small computer itself and can execute macros, patterns, etc. I was worried about a possible firmware bug or something worse. At the moment, I’m honestly hesitant to plug it back in and am using an old Dell keyboard instead.

Importantly, I wasn’t pressing any keys at the time of the incident.

Now I’m quite unsure what could have caused this.

Is there any way to trace this in Firefox (e.g., via logs)?

And is there any (event) log where I could check what triggered the UAC prompt?

One more thing I noticed: I shut down the PC afterward and turned it back on later that evening. Everything booted normally and is still running fine today. However, Firefox updated itself yesterday from version 148.2 to 149. Maybe that was somehow related (though there’s no indication in the Firefox update history that anything failed or similar).

Hello all.

I'm running into frequent tab crashes, very commonly on pages that have a lot of elements, or things to render on the page.

Specifically, I am being challenged by gmail, where switching to my inbox will 100% crash my tab.

Here are a few crash reports to look at from this gmail example. It is not gmail alone that causes this, other websites such as Zillow, youtube, etc. Pages that contain a lot of information and pictures typically cause this.

https://crash-stats.mozilla.org/report/index/d4965ad5-0592-4b0a-bc67-4e8080260328#tab-details https://crash-stats.mozilla.org/report/index/f48490e0-6aaf-423c-80a1-e2aaf0260328#tab-details

I also want to mention that I have the exact same profile loaded onto another machine, and I experience no issues. I do not believe this is an extension issue, but I am open to disabling all of them and generating more crash reports if anyone would like for me to try that.

What stuns me the most in these crash reports is the reported amount of "available virtual memory" exceeding far beyond what I have available on my machine. Can anyone help pinpoint what about my system would keep making Firefox think I have this much available virtual memory?

Thanks for any advice and help!

After new update my Firefox is completely bricked. I can't do anything with it, it just wiped all of my tabs out and now I can't open any, search or do anything.

All my settings are blank, running private doesn't help. If I right click a tab, it shows up with "new" and all of the other opens are blank.

It first happened after the update, only my first and last tab had titles. All the other tabs open turned blank, and could not be accessed. Then the second time I accessed them, they had all disappeared.

Tried reinstalling, didn't help.

On desktop, but had to make this on mobile because I can't even get to the support website.

My firefox has been closing while I am away from my computers. I have a few computer running linux (Ubuntu 24.04) and one in mac osx (Big Sur). Usually, I can start firefox and it will remember my tabs which is annoying but still manageable. However, once in a while, (which happened yesterday), all the firefox closed on all the computers and it forgot my tabs when I start firefox again.

I have already set app.update.auto to false on all of the firefox instance prior to this incident to avoid firefox update would close out firefox itself. So if anyone has any idea of what to check to see why firefox keep closing and/or why once in a while it will not remember my tabs, I would really appreciate it.

Hello,

I would like to report a potential bug in Mozilla Firefox related to recent updates.

After downloading a PDF file and opening it directly in the browser, the tab crashes. Following this crash, it becomes impossible to open any files (regardless of file type) within the browser — every attempt results in another tab crash. The crash report cannot be reviewed, as the tab fails immediately and can only be closed.

As a temporary workaround, changing the default PDF handler to an external application prevents the issue. However, this is not a viable solution for us, since some of our internal systems require PDFs to open directly in the browser after download.

We have verified that this issue does NOT occur in version 148.0.2 — everything works correctly there. However, after updating to version 149.0, the problem reappears consistently. Firefox also automatically updates after synchronization, making it difficult to remain on a stable version.

According to the release notes, there were changes in PDF handling in recent updates, so this may be related to a technical regression.

Could you please investigate this issue or advise on a proper fix or workaround?

All firefox windows just disappear after a random amount of time. Where can I look for possible logs of what's happening. Didn't see anything obvious in Event Viewer>

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.
