Firefox Community Forum

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?

Hi there,

I'm running Firefox (136.0.1) on my mac laptop (MacOs 15.1) Just recently it has started silently failing. I move away from the window and after a short period (hour or so) I can see it is no longer running. When I start it again it offers to recover the session for me.

I've tried checking about:crashes but it just says no crash reports have been submitted. There are no details of unsubmitted reports.

Thanks, John

Ever since I updated Firefox to version 110, I’ve been experiencing consistent crashes when trying to visit certain websites, such asIrish Kilt Shop. The issue started immediately after the update, and I’ve tried restarting my computer, clearing the cache, and disabling extensions, but the problem persists. I’m running Windows 10 and have no issues with other browsers.

I have notebook no issues, My Desktop however I get tabs crashing with firefox, Apache Open Office but not with Doc files in open office and not with chrome and Edge they run without any issues. My computer is awsome it seems to me this version of firefox is either being pushed out or its not coping with large loads. I removed all of my 32gb ram tonight just to test the ram my ram is fine.

I have been with you since the netscape days and I prefer your features butthe browser needs a rebuild with the current look and workings and also the other benifits chrome offer with pdf etc Thank you for reading this. Bill Shannon

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

Report ID Date Submitted bp-a9b8bd6e-9258-4a25-badc-bda480250308 08/03/2025, 13:41

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

It opened every time I typed.

I asked ChatGPT and turned off both "Search page when you start typing" in settings and made some config files to block it.

It still shows up when I press ' or / outside a text input.

There are video playback issues on both desktop Firefox and Android Firefox, but there is no category for both. However, I considered not being able to play the videos at all a more serious issue.

https://files.catbox.moe/aypxqq.mp4 This is a sample video.

The HEVC video plays on android, but with lag as if there were no hardware acceleration while it plays fine on Chromium-based browsers. This same issue was present on desktop Firefox, but then hevc support disappeared in one of the updates altogether.

https://ott.dolby.com/codec_test/index.html

This page shows that HEVC isn't supported, despite nobody on the web reporting this bug. And neither is HDR supported for some reason. Despite Firefox Android having the same report from that site apart from the user agent, it's seemingly able to decode that video on CPU, whereas on Windows it shows a Mimetype error. Disabling hardware acceleration doesn't make Firefox play it on the CPU. Is there a fix for these?

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

Firefox crashes randomly during video playback. I've submitted over 10 crash reports. Here's the two latest crash report (which includes my device's hardware information): https://crash-stats.mozilla.org/report/index/81eb1750-1dd0-490d-9eb1-d3c2c0250224 https://crash-stats.mozilla.org/report/index/6682a7f2-836a-4365-938e-c9ab20250224

I'm on Fedora 41 + gnome, but this issue persisted even in Windows 11, which caused BSOD therefore I made the switch to linux (At least in linux it doesn't crash the whole system, only firefox). If you need any additional information let me know. I can run journalctl/dmesg if required.

I've already tried things like restarting in safe mode (troubleshoot mode), refreshing firefox etc. Didn't work.

Thanks in advance!

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 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

I use firefox beta and noticed that firefox always closes exactly when a new hour hits. The moment it hits say exactly 4:00, 5:00, 6:00, or so on for every hour of the day, the app crashes. I also tried this on the standard firefox and the same thing happens. I even decided to alter my device time in settings and set the time to 11.59 only to have the app crash the moment it turns 12. This is the same for any other time of day I set. I tried changing battery optimization and storage restrictions/optimization and nothing seems to work.

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.
