A few days ago, trying to free up some memory and improve my computer's performance, I deleted the cache and tracking cookies from Firefox (using AVG TuneUp). Since then, I can only load a certain, variable number of tabs and/or pages without every new or reactivated tab or page claiming to have crashed (although about:crashes says that no reports have been submitted). Restoring those pages seems impossible without restarting Firefox or the whole computer. The problem persists in Troubleshoot mode, but as far as I can tell doesn't affect Chrome, although that used even more RAM. I've tried culling open tabs (of which I still probably have far too many, but it's never been an issue before), using the OneTab extension to reduce them to lists of URLs, disabling and re-enabling hardware acceleration, updating Firefox, checking for file corruption and RAM errors and even uninstalling and reinstalling the program, but nothing's worked so far. What might be going on, and what else can I try?

I run Firefox under Linux Mint. Both are always update to the latest level. Over the past 1 to 1.5 years, across updates to both Firefox and Mint and multiple 'clean' installs of Firefox, I have experienced many crashes from Firefox per week. Sometimes there will be as many as 5 per day, but never less than one per day. During the same period I have also been running Vivaldi; it has not crashed once in that time. Now I have to do something. If there is a simple way to perform 'problem source identification', that is within my capability, I would be grateful for advice. If there is not, then clearly I will have to un-install Firefox.

As far as I can tell both of these browsers run with just 1 add-on/extension: uBlock Origin. Disabling this extension in Firefox does not stop Firefox from crashing.

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?!?

Started using Netscape and been with Firefox ever since it started. For the last few months, I find that my Draytek 2866Lac router randomly crashes and resets itself when I am using Firefox. I cannot pin it down to opening any particular website but it seems to be related to opening a new tab / link. I have FF set to open new tab automatically and no extensions (other than British English) are in use. Using FF, I can seldom go more than 5 -6 hours between resets. Not using FF, I have now managed 2 days constant uptime on the router - which is a fantastic change! Is there something peculiar with my system and any ideas how I can get stability again please?

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.

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.

Ok for some reason any of my browsers tabs are crashing I just do whatever it is whether i search or watch movie and after some time 'Gah! your tab crashed' and it's pretty annoying, my discord happens to restart it self and I've exhausted literally anything from re-installing, deleting caches folders absolutely anything.

I've uploaded my latest 2 crashes and hopefully someone can read it and let m know about anything, Thanks in advance!

Can you guys check why your netflix account is getting logged out every time regardless of how many times you logged in and for prime video if you play any video i'm getting video player error, can you please check

When I try to log in, I get the "your account has been locked for security reasons" message. I understand I'm supposed to get an email with a code to confirm my identity, but I didn't. I tried multiple times in the last few days. The only mail I got from Mozilla is one asking me to log in to change my password. But obviously, I can't log in.

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.

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.

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

The browser keeps crashing. I want to remove it from my Win 10 computer but uninstall only lets me do a refresh. I need to remove it to see if it is Firefox or some other issue. How do I remove the software?

Thanks for your help with this matter.

Best regards,

TV signal, and audio cuts out (black screen) when using mouse arrow to drag scroll in side bar. Also gives a loud audible "click" as sound is temporarily cut out. ( Most probably whole HDMI signal is cut)

Black screen bug happens randomly with You tube with no mouse or keyboard action, but 100% repeatable with this website when scrolling :

Please advise how to fix

Attempted to do an Firefox update more than a month ago on my HP (microsoft windows) computer. Everytime I open my computer I gt the Firefox Crash Reporter Window. When I hit the Quit firefox box it submits the crash report and then I X out the box. I cannot use Firefox as a browser. The DISASTER is that I CANNOT open any files previously downloaded while using Firefox (eg PDF files). I get the crash report box. I NEED these files!

Please HELP!

I have noticed that just recently videos across all different websites are not displaying properly. The image part of the video is a green scrambled mess. The audio is fine, but the images are wrong. I am not having this issue on a different browser, and I'm not sure what I'm supposed to do. I don't know if changing any of the settings will help or if there's a bug in one of the updates.
