Summary - Firefox crashes repeatedly. yesterday, I decided to switch to Firefox after using Chrome for a while. it worked fine and I synced my data from Chrome. today, at some point I noticed Firefox is no longer open in my taskbar. I decided to reopen it - it crashed. since that moment it has never worked again. I tried launching it in safe mode (firefox.exe -safe-mode), didn't work. tried reinstalling it, didn't work. manually deleted the files from C:\Program Files and AppData, installed Firefox again, didn't work. reinstalled gpu drivers, didn't work. sfc /scannow-ed, you guessed it - still crashes. what else could I possibly try? please help.

When testing our web application, I can consistently get the tab to crash in Firefox (not other browsers). This happens even when running in Troubleshoot mode.

A few of the submitted crashes: bp-f1e47e32-aa7e-4080-880c-34f160250710 bp-622b9363-fa50-4b15-b605-87c3e0250702

Can anyone tell what is causing it to crash, and if we can do something to fix it?

Why would you cancel coverage on FakeSpot? This was a tool used frequently by multiple people that I knew, and what it really feels like is that FireFox is being bought out and removing it to make it easier for all of the scammers to continue to pump us full of fake garbage. Really disappointing to see this service being discontinued and hoping that you reconsider.

Hello! I've been seeing some strange behavior on firefox launch or on new profile launch. There is a popup during startup, can't see it on the screen but I can see it in tray. Is this normal or no? I observed it on two different hp notebooks so far.

I have created several groups (currently 4 with a total of 11 tabs combined). When a group is closed, do those tabs become inactive, reducing their impact on Firefox/computer performance, or do they still remain active and impacting overall performance?

Hi,

Whenever I try to watch videos on Anime Slayer APK in Firefox, I get a message saying the browser is “unsupported” or the video just won’t play. I’m using the latest version of Firefox on Windows, and I’ve already cleared my cache and disabled extensions, but the issue persists.

Interestingly, the same videos work fine in Chrome and Edge — so it seems like a Firefox-specific problem.

Is there some setting or add-on I need to enable to make it work? Or is this a known compatibility issue with certain websites?

Thanks for any help you can provide — I’d rather not switch browsers if I can avoid it.

I want to use a different credit card. If I type in a new credit it tells me it is not a valid number. Somehow the system remembers one credit card and will not let me use a different card

Hello,

Not sure if posted under the right section.

Recently started having an issue trying to sign in to Microsoft Outlook (formally Hotmail) Web. I don't recall any changes i made or updates.

When i try to sign in, it opens a new tab and takes me back to the sign in page. This just continues.

Tried using MS Edge and don't have the issue.

So far tried Safe Mode which disabled add-ons, which are currently Add Block plus, and New Tab Override and the issue remains. Not sure if i tried the refresh option but i think it removes the extensions which is not the end of the world.

Added a few images, one shows duplicate tabs, which will continue

Firefox version 140.0.4 (64-bit)

Any ideas whats going

Thanks

Hi Team, I am using Linux Mint 20 Cinnamon. Cinnamon version is 4.6.6. The issue is that I was browsing and by mistake I selected one tab then dragged it for sometime and then released the tab but that created a new window and now the old windows are not visible in ALT + Tab function. The windows are showing in the Firefox task manager and also the box icon in the top right corner in that "open tabs". Now I am not able to even change the window or able to access the opened tabs. Attached the screenshot and as you can see in that there are total 4 windows showing in firefox and one as active but in the bottom on the firefox icon you can see its only 1 window. How can I access the remaining 3 windows? Found one ticket (https://support.mozilla.org/en-US/questions/1477845) in this the recommend solution does not work. When I try to click on the window 1 tabs then I do not get any response. I tried both the solution but none worked.

Thanks for the help in advance. @Mozilla team member is seeing please check and fix this bug if possible.

How can I sync my groups between different instances of Firefox (other computer)? That should cover both active and saved groups to have real usefulness. Thank you

Hello all.

I chose "Use Adobe Acrobat Reader" for open PDF in settings and it works fine until I closed Firefox and open it again. The setting bounce to "Open in Firefox". Then, I tried choosing "Always Ask", closing Firefox and opening Firefox again. The setting preserved as "Always Ask" and did not bounce to "Open in Firefox".

I checked handler.json in user profile folder after I chose "Use Adobe Acrobat Reader" for PDF, action is 4: {"defaultHandlersVersion":{},"mimeTypes":{"application/pdf":{"action":4,"extensions":["pdf"],"handlers":[{"name":"AcroRd32.exe","path":"C:\\Program Files (x86)\\Adobe\\Acrobat Reader DC\\Reader\\AcroRd32.exe"}]}},"schemes":{}}

But then after restarting Firefox, it changed to 3: {"defaultHandlersVersion":{},"mimeTypes":{"application/pdf":{"action":3,"extensions":["pdf"],"handlers":[{"name":"AcroRd32.exe","path":"C:\\Program Files (x86)\\Adobe\\Acrobat Reader DC\\Reader\\AcroRd32.exe"}]}},"schemes":{}}

Checked handler.json with "Always ask". Before and after restarting Firefox, action is 1, which is expected and correct.

Some other colleagues reported the same issues as well. I am thinking if this is a bug from Firefox.

Some more notes here:

• The issue only happens to PDF, for other Content types, all good.
• Already disabled all plug-ins and extensions.
• Tried refreshing Firefox in safe mode
• Tried choosing another external PDF reader Foxit
• Firefox version is 140.0.2

Some screenshots are attached showing where it is.

Hope someone can help on it. Thanks in advance.
