Hello,

I would like to report a potential bug in Mozilla Firefox related to recent updates.

After downloading a PDF file and opening it directly in the browser, the tab crashes. Following this crash, it becomes impossible to open any files (regardless of file type) within the browser — every attempt results in another tab crash. The crash report cannot be reviewed, as the tab fails immediately and can only be closed.

As a temporary workaround, changing the default PDF handler to an external application prevents the issue. However, this is not a viable solution for us, since some of our internal systems require PDFs to open directly in the browser after download.

We have verified that this issue does NOT occur in version 148.0.2 — everything works correctly there. However, after updating to version 149.0, the problem reappears consistently. Firefox also automatically updates after synchronization, making it difficult to remain on a stable version.

According to the release notes, there were changes in PDF handling in recent updates, so this may be related to a technical regression.

Could you please investigate this issue or advise on a proper fix or workaround?

Hello,

I am experiencing a recurring issue with Firefox on Kali Linux.

Environment:

- OS: Kali Linux (running inside Termux on Android) - Connection: VNC (RealVNC) - Device: Android phone (low RAM) - Desktop: XFCE

Problem: Whenever I open Firefox, tabs frequently crash with the message: “Gah. Your tab just crashed.”

What I already tried:

- Disabled hardware acceleration - Disabled recommended performance settings - Ran Firefox in safe mode - Created a new Firefox profile - Lowered VNC resolution - Restarted the system

The problem still persists.

I believe this may be related to graphics rendering or memory limitations under VNC/Termux.

Please advise if there is a workaround or configuration that can prevent this crash.

Thank you for your support.

I have been having issues with Firefox since the new update. It will work for 5-10 minutes and then cashes and freezes my Macbook. I then have to restart my entire system. I have always loved using Firefox but lately its more of a pain and have been thinking of changing,

Hi there, I'm wondering why Firefox is crashing tabs like crazy for me the last few days. Chat Gpt reckons these screenshots indicate a problem with the JavaScript Engine. I'm looking for expert help to differentiate the cause so I can be sure my hardware isn't damaged. Scrolling fb or youtube , even using chat gpt and firefox just throws me a crashed tab. I have uploaded the reports that chat gpt has reviewed to ensure it is being accurate.

I'm mainly looking to find out so I can rule out if there are problems with my hardware .Any help identifying the source of the errors would be greatly appreciated!

I have just reinstalled Windows 10 and now I cannot see my old firex=ox history from prior to the reinstall of Windows 10 Is there a solution and also i downloaded firefox and now every tab crashes immediately

I have tried over several days to uninstall and reinstall Firefox to avoid tabs constantly crashing. While I've done this and multiple shut downs and restarts it continues to crash and can't figure out why. Please help.

why does my fire fox keep crashing the screen goes black i get tab just crashed already updated and cleaned my ram and did everything i could think of and still crashing am still crashing on troubleshooting mode

The dialogue box says "The application is exiting and cannot service this request"

Nonetheless Firefox seem to be functioning as I would expect apart from the irritating appearance of the dialogue box that I have described.

I attached a scan of the dialogue box - how do I prevent it appearing and/or is it signifying anything important,

Windows 11 Home Version 25H2

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.

Okay. So I downloaded Firefox on my chromebook from flathub, but it keeps crashing. I open a new tab: it crashes. I close a tab: it crashes. I don't open or close anything: it crashes. I don't touch anything: it crashes.

I've says that either my theme or one of my add-ons is causing the crashes but I removed my theme and it still crashes and I can't remove any add-on because it crashes if I try to open a new tab.

Now, did/does anyone else have this problem or am I just stupid and missing a very obvious thing.

Getting "Mozilla Firefox Crash Reporter" problem message when attempting to print files (Docs & Sheets) from Google Cloud. Errors messages have appeared on Lenova Thinkpad laptop in Firefox since mid Dec update. Can print existing files located on desktop, just not from cloud. Both HP and Epson Printers test fine, can print 'test pages'. Tried downloading files from cloud to pc....opening downloads, got same Firefox problem message and crashed. Have used same firefox browser and same printers for several years. Rebooted several times, same error. Can print, 'printer test pages'. Do I have a switch turned off/on or is this a browser problem. Any assistance would be appreciated.

Hello, I’ve been increasingly frustrated over the past few weeks with your browser, which I prefer over all the others, because it keeps crashing constantly. I’ve tried several small fixes suggested by IT professionals, such as clearing the cache, running an antivirus scan, and deleting my browsing history, but the issue persists with no improvement. At this point, my last option seems to be uninstalling and reinstalling the application, but I’m concerned about losing my bookmarks. Could you please advise me on how to resolve this issue? M.

I have asked several times, and received no responses that helped. I am continuously hammered with GAH! I've tried everything I've found both from Mozilla, and Google AI, but have had no solutions. What am I missing? If I have to uninstall, then reinstall Firefox, I'm going back to one of the better versions, like 98, or 99, or earlier, which I've got on old HDD's that still function. Thanks to anybody who can offer a real solution.
