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.

Yesterday Firefox started crashing tabs on load of a handful of websites that are seemingly random, like Twitter and a few shopping site tabs I had open. It wasn't after a system update or anything, it just started happening while Firefox was already open and those tabs had already been open and loaded. I've tried clearing my cache, site data, reinstalling Firefox, and it still does it. Upon further investigation, it seems to be something regarding libfontconfig, and mostly specific to users of openSUSE Tumbleweed.

Tabs will crash over and over again. I can barely look at any given page for longer than a minute or two. What happened?? Firefox was never like this before. It just crashed in the middle of me typing this LMAO. Using Brave in the meantime. This is ridiculous.

I am experiencing significant stability issues with Firefox. When I use YouTube, the entire browser frequently hangs (becomes unresponsive) and eventually crashes. This does not happen on all websites, but it is consistent when playing video content on YouTube.

• Symptoms: The browser "stacks" or freezes completely; I cannot click tabs or menus until the browser finally closes/crashes.

• Extensions: I am currently using extensions like SponsorBlock, uBlock origin. I am unsure if this is the cause, but the issue persists during video playback.

• Hardware: I am running this on a laptop with an 16gb 4800mhz RAM, i7 12th Gen processor and an RTX 3070 GPU.

1. Is there a known compatibility issue between current Firefox builds and SponsorBlock or similar video-modifying extensions?

1. Could this be related to hardware acceleration settings with my NVIDIA GPU?

1. What steps should I take to provide crash logs to help identify the root cause?

So for three days now, my firefox constantly crashes. I would be reading a story online or watching a video on Youtube and then it will suddenly freeze. In videos, it'll still play the sound but the screen will freeze. I can't pause or stop it. Then either Firefox crashes and closes or I have to close it for it to stop. Sometimes, when I try opening it again, it still won't open. I used to have 50 tabs open and never ad this issue. After this, I closed all the open tabs, even deactivated a bunch of extensions, run malware detection, and still the issue continues. I don't know what the problem is. I even followed instructions and deactivated hardware acceleration options in Performance. And I have all AI options turned off too. The app also recently was updated.

crash report bp-e455fd8b-e30b-4cdc-811a-346ac0260607

As the title states, every time I try to zoom into a page using pinch and zoom with my touch-pad, firefox nightly crashes. However, if I try to zoom in using CTRL+ and CTRL-, it works just fine.

I have tried to disable hardware acceleration but it didnt help.

These are the logs which I obtained from the crash reporter: AdapterDeviceID: 0x46a8 AdapterDriverVendor: mesa/iris AdapterDriverVersion: 24.2.8.0 AdapterVendorID: 0x8086 AvailablePageFile: 1012457472 AvailablePhysicalMemory: 10165415936 AvailableSwapMemory: 2000678912 AvailableVirtualMemory: 12812111872 BackgroundTaskMode: 0 BuildID: 20250613160838 ContentSandboxCapabilities: 119 ContentSandboxCapable: 1 ContentSandboxLevel: 6 CrashTime: 1750302886 DOMFissionEnabled: 1 DOMIPCEnabled: 1 DesktopEnvironment: ubuntu:gnome EMCheckCompatibility: true EventLoopNestingLevel: 1 GpuSandboxLevel: 0 GraphicsCriticalError: |[0][GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt (t=148.335) GraphicsNumActiveRenderers: 2 GraphicsNumRenderers: 1 HeadlessMode: 0 InstallTime: 1749869266 IsWayland: 1 LastStartupWasCrash: 0 LinuxUnderMemoryPressure: 0 MozCrashReason: internal error: entered unreachable code NimbusEnrollments: upgrade-spotlight-rollout:treatment,fx-accounts-ping-release-rollout-2:control,disable-ads-startup-cache:control,desktop-nightly-show-relay-to-13501-logged-out-users:synthetic-control,desktop-credit-card-autofill-global-enablement-rollout-nightly:creditcard-enable,enable-enrollment-status-telemetry-in-firefox-desktop:control,desktop-address-autofill-india-nightly-rollout:control,fpp-screen-avail-hardware-concurrency-desktop:control,hide-descriptions-on-newtab-articles-fix-rollout:control Notes: Ubuntu Core 24FP(D10-L1000-W0000000-T01) WR?

Any help or direction would be appreciated, Thanks!

Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

I wasn't sure what to select for the type of question so you can move it if you think another type would be better. I would have selected crashes but that isn't an option.

It happened again a few minutes ago while watching Star Trek First Contact. The Phoenix was about to go to warp and Firefox CTD with no crash reporter and when I looked in about:crashes there was no crash report. This exact situation happened twice while watching the movie Signal unknown or whatever the title is.

Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?

this is the latest crash report. had 19 crashes in about 1 hour. i have noticed when i put stress on my pc IE playing a game the crashes are less. i have 64g ram i9 14900k cpu. disabled all extenstions have uninstalled and reinstalled firefox but nothing im doing seems to help.

any help would be great.

Firefox has been crashing several times an hour for multiple days. I have tried:

Changing/Upgrading RAM Reinstalling Firefox Resetting Firefox Reinstalling Windows Updating Drivers

Every time I make Firefox full-screen, it immediately crashes and shuts down. I have restarted the computer, uninstalled and reinstalled Firefox, but it still doesn't work.

I believe this problem is caused by a false crash recovery loop, every time I open firefox it'll close again and then give me an annoying red striped address bar. I'm sure its not my extensions because I only have Ublock Origin installed.

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

Firefox began crashing a few days ago and has crashed during each log in and use today. Most recently trying to download and print documents. I have disabled all extensions, have text file of the Third=Party modules and Submitted Crash Reports.
