On May 1st, when I launched Firefox(afternoon some time on US East coast) it ran an update to 138.0.1. When it was done, it did not launch. So I clicked the icon on my desktop and it came up, but then closed out after about 15 seconds. When I reopened it, it asked to continue in troubleshooting mode or refresh. I tried both. No luck. I restarted and even uninstall and reinstalled the latest version as well as tried installing 137.

I have tried with virus/malware protection/firewall off. I have restarted. My page file is default. I tried renaming the firefox.exe to something else. I tried creating an new firefox profile(firefox.exe -p) but that crashes too.

I installed the latest version of Firefox Nightly and it stays open just fine. But when I launch the regular firefox, they both close.

I also installed the Firefox app from the Windows store and it behaves the same as the one from the mozilla website.

Endless crashes, going on for months (4-5) and no sign of any fixes. As far as I'm concerned, Firefox is totally broken and I'll have to switch away. It's unusable. A crash every ten minutes.

Я так понял, что в файерфокс больше одной вкладки открывать нельзя? Если было открыто более десяти вкладок в браузере, то рано, или поздно они обязательно слетят, без возможности восстановления? Очень удобно... Если честно, то вы- пидарасы... Перед открытием браузера, после обновления, вы выкладываете вкладку об обновлении версии... Вы обязаны выкладывать ссылку на восстановление ранее открытых вкладок. Суки! Восстановите мои, ранее открытые вкладки!!

Firefox has been running smoothly for the last 6 months. Recently I started receiving Firefox Crash Reporter dialog boxes when opening the app. The app never opens, but I receive three crash reporter dialog boxes.

What I have tried: Repair Reinstall Deleted every Mozilla folder in App cache and other device locations. Did another reinstall. App never loads and I receive a crash report. Updated Windows. Restarted laptop. Etc. Everything else on the device runs perfectly.

Installed newest version of Windows 11 and now no tabs will load on browser and all show as crashed. Have uninstalled, reinstalled, refreshed and tried all I could and no changes. Would love any help.

Since 2/11, I have eleven aboutg:crashes crash reports. Tab crashes (i.e Youtube), browser crashes. Sometimes when I have Firefox and Chrome open at the same time, for an extended length of time, (I reluctantly use Chrome when Firefox has a problem with a site) they both crash.

I've opened related threads here in the past with no help offered, so maybe I can get a suggestion where else to get help?

I have Firefox on two separate computers, a desktop running Win7Prof64bit and a laptop running Win10Pro 64bit. Both Firefox installations crash constantly, ie every 10 - 15 mins. They show the "Gah! Firefox just crashed. Please tell us what you were doing", and the box to return the data to Mozilla. With Restore This Tab at the bottom.

I always send you these reports but in about a year, the problem remains the same. Nothing has improved, I never hear back from you. Two different PCs, two different OSs, constant reports, no improvement. Why do I never hear from you? Why does this problem continue endlessly? I'm wasting my time sending you the reports. You take no notice. If you do, why does the problem continue and why do I never hear from you?

Firefox crashes constantly when I load it mostly when in youtube though. I notice so I am not sure what is causing it to crash it could be ublock origin as I use that to block ads on youtube that is the only thing I can think of or maybe the return dislike button but here is my crash report below ID bp-8f27f4a1-7ed0-492e-823d-e57af0250304

Since updating Thunderbird crashes shortly after starting or sooner if I initiate an update check. If I pull the internet connection and the update check fails it doesn't crash.

Over the past few weeks, tabs keep crashing several times a day. It happens most often on X, but this morning, a tab crashed while completing an online order (grrr). My computer is up to date, cookies, cache and history cleared regularly and today I "refreshed" Firefox. In less than an hour, tab crashed again. What is going on???

I'm very close to changing browsers.

A (supposed) Firefox update on my computer at 13:00 Tuesday 8th January AEST crashed and eliminated all my open tabs and all of my Bookmarks. The update was unusual - Firefox usually does it's updates when you start using it. This time I was using Firefox doing multiple things and boom, request for an update then collapse. Did anyone else have this problem? Does anyone know why such a catastrophic event might have happened.

1. Whenever I open Firefox for the first time since boot, it crashes, and I have to click on it a second time for a window to actually show up. Once it shows up, it's forgotten all about the previous session - none of my tabs re-open, the window opens up maximized.

2. Whenever I close the last open window, my previous tabs are completely forgotten. Checking task manager reveals that there are 10 or 11 Firefox processes that are still running.

• I have a second Windows 11 device that DOESN'T exhibit any of these issues and works correctly. Closing Firefox does not leave any running processes around.
• "Open previous windows and tabs" is enabled in options.
• "Firefox will: Remember history" is set in the History options.
• Both devices are running Firefox 137.0.2 64 bit.

Since updating to version 135 all the tabs crash. I've uninstalled\reinstalled, deleted app data, disabled AV and created a new profile. The only time it works is in troubleshooting mode. I've looked at extensions and plugins and I'm only seeing OpenH264 video codec and Widevine content decryption. I've disabled those but still get the crashed tabs.

I'm also not generating any crash logs.

I always use the middle mouse button (pressing the scroll wheel) to open and close new tabs, but since the update, it doesn't work anymore and now types "=" if the cursor is in a text field. For context, I use an MX Master S3, mapped with Logi Options+.

Anyone else having this issue? How do I roll back to the previous version??

SOLVED: It was a bug with Logi Options+, not Firefox. When I hovered over the tab for the presets I had for CaptureOne, I noticed it also said Firefox. So seems something weird happened there. Deleted that preset and the issue in Firefox went away.

I couldn't find a way to delete this thread, though.

Hi everyone, I've been experiencing a persistent issue where my Firefox (Windows 10) randomly crashes or closes. I recently noticed that this always happens when a JSON file appears in the following directory: C:\Program Files\Mozilla Firefox\distribution The strange thing is that this file shouldn't even be there, as this is my personal computer and it is not managed by any organization. I have already tried deleting or renaming the file, but after a seemingly random period, it gets recreated automatically. Here’s what I have tried so far, without success: - Deleting/renaming the file - Checking the registry at HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Firefox (but the "Mozilla" folder does not exist there) - I have never used any third-party antivirus software (only Windows Defender) Does anyone have an idea where this file might be coming from or how I can prevent it from being recreated? I’m not very tech-savvy, so I would greatly appreciate simple explanations or step-by-step instructions. Thanks in advance for any help!

Thought only Ubuntu's Linux Firefox 136.0 was 'unstable' on my Gateway E-475M laptop - crashes, restores session then freezes only to log me out, then completely locking up requiring holding down power button and rebooting...

Now, even Firefox 136.0 on WIN7 is crashing, then restores session only to go to the 'blue screen of death' requiring holding down the power button and rebooting...

Evidently, the problem is not with Ubuntu or WIN7, but either: Firefox (Linux or win version); or, the Gateway E-475M laptop (2.0GHz CPU, 4Gb RAM, 8Gb swapfile, Harddrive at 61% usage, Linux/Win on separate booting partitions, LAN + usb & pci wifi's, etc.) - both OS's used to work fine, but as upgrades to Firefox have come along, they have steadily gotten more and more unstable...

Sometime, I'm only making a bookmark, and it starts this circus act... does it on differing websites, etc. Firefox is the only thing loaded - using two windows on two different monitors ...at a loss as to what to do - Firefox is supposed to be THE lightest-weight browser out there, and was for awhile... the only extension used on both systems is "NoScript" - could that be causing the disturbance in the force?!?

hello, i have a huge issue with my firefox and i cant seem to fix it or somehow understand the cause why my tabs sometimes browser crashes unexpectedly and sometimes i get a blue screen on my laptop. maybe there is a problem with my pc but it doesnt change the fact why firefox tabs are crashing really often this is one of my latest crash reports: https://crash-stats.mozilla.org/report/index/3721bbdd-5f3a-4b02-bd0d-60c1e0250208

hi, i genuinely have no idea why this is happening because it started crashing all of a sudden and it doesnt happen mid-use, i cant use it at all and restarting firefox just results in another crash and so on. what am i supposed to do??

Firefox crashes every day or so on my home computer. The most common error message is "kmode exception not handled." I've tried the suggested fixes. Nothing helps. The crashes are not being recorded in "about crashes" or in %APPDATA%\Mozilla\Firefox\Crash Reports\. So it seems the crash reporter has to be fixed before the problem causing the crashes can be identified. Firefox does not crash on my office computer and no other program causes my home computer to crash. Thank you.
