My Firefox Browser keeps crashing at random times. I was using Chrome previously and it was worse than the Firefox performance. I just installed 128 GB of brand new DDR5 RAM which I tested in windows with no error. I have no malware on my computer currently. I ran all of the usual checks that you suggested with regard to extensions and cache. Here is the most recent report ID that was generated by Firefox:

bp-7c5d5dcf-2fc9-40a3-9659-ff55f0250424

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.

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.

When attempting to attach file to enail from File Explorer, or do a "Save as" of a photo, Firefox crashes and a "Firefox Crash Reporter" box appears, which instructs me to restart Firefox.

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?

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 Desktop (x64) worked normally until the version 135 update was installed. Now tabs (even a single tab) crash after startup unless Firefox is run in troubleshooting mode or Windows 8 compatibility mode. OS is Windows 10 Pro (x64) 22H2 on ThinkPad E495 (AMD Ryzen 5 3500U) Things that haven't resolved the problem: - Remove extensions and themes - Refresh Firefox - Reinstall Firefox - Updating Visual C++ 2015-2022 with Redistributable (x64) version 14.42.34438 - Updating Firefox to version 135.0.1 and subsequently to version 136.0, however updater only works in Windows 8 compatibility mode - Full system scan for malware (none found) Note: Extensions NoScript and Cookie AutoDelete work normally with Firefox running in Windows 8 compatibility mode.

Hi, I just installed the latest update (I think it's 136.0.2). I guess I skipped some/several versions. Suddenly my main menu isn't workin anymore (clicking it with the mouse, that is) There is some overlay which I can't find out, how to remove. Even the Minimize/Maximize/Close buttons don't have any function. Luckily I can still access the menu via keyboard shortcuts. How can I remove that overlay bar ... or did I catch some malware ?

Why does Firefox Desktop now completely crash every time I press the Ctrl and cursor keys whilst navigating through text?!!! Very frustrating and I've had to abandon using your app completely. Please fix and redeploy your app as a matter of extreme urgency!!! thanks

Firefox can't seem to be able to import from Vivaldi. Whether I try, it just always takes on and on until it crashes. I remember it working whenever I tried to import browser data before trying to import from Vivaldi to Firefox.

Hello,

We ran in-place upgrade from Windows 10 to Windows 11 on a number of machines. Afterwards, web sites like citibank.com or linkedin.com crash as soon as the page is loaded.

We've uninstalled/reinstalled Firefox, deleted all data, nothing worked.

Anyone else experience this problem? Is there a fix?

Thank you!

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.

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

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?

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.
