When I look up the error message I get, everyone I see who got it can't open Firefox, but I can open it fine. For me, I have Firefox as my default browser and when another program (tModLoader on Steam) tries to open it, it gives me "Profile Missing," "Your Firefox profile cannot be loaded. It may be missing or inaccessible." I don't know if it gives the same error for other programs because I can't think of any programs that open my default browser. When I switch my default browser to Edge, the program can open Edge fine.

Whenever I attempt to access DRM content such as netflix or spotify I am notified that the WidevineCdm plugin has crashed. I'm running firefox version 101.0.1 on Kubuntu 22.04, I am running the debian package release, but I had this issue with the snap version too. I've submitted crash reports, but they're all "EMPTY: no crashing thread" (https://crash-stats.mozilla.org/report/index/20af09a5-6bc4-4719-9242-38f5c0220614 here's one).

About two days ago the cursor started disappearing / flashing when browsing in Firefox. It does not mater where the cursor is placed on the screen either the arrow or the hand will flash when moving. My system is a windows pro 10 system with all updates, last updates for W10 were made a couple of weeks ago, on Firefox whenever it asks to upgrade I do it.

Specifically: 1. If the mouse is stationary there is no cursor, if I move it the cursor flashes. 2. When the system comes up and I launch Firefox all is OK for about 2 – 3 minutes then the flashing begins. 3. If I stop Firefox ie “X” it and restart it the flashing occurs within 0 – 30 seconds. 4. If I restart the PC steps 2 & 3 repeat.

I have two other PC’s Windows Home, and Windows 7, as well as a laptop with Windows Home all with Firefox 101.0.1 all up to date all do not have the above issue. This does not occur with any other programs. I have two monitors, tried Firefox on each makes no difference same problem.

I have tried searching the internet and all I find is about Caret which is off. I uninstalled Firefox and installed it. That made no difference.

Any assistance will be appreciated.

Thank You

Bob

For the past few weeks I've been receiving numerous firefox crash reports & also when trying to open firefox an error indication that firefox is already open. I've never had this problem with firefox in the past, and have been an avid firefox user for many many years.

This occurred on my old desktop computer which died this week & is also occurring with my brand new, out of the box HP laptop computer (with ALL the windows updates and HP updates installed); The old computer used Windows 10 Pro, the new computer uses Windows 10 Home.

My old computer used just the windows defender for protection, but my new laptop comes with a 1 month trial of McAfee which I am using until the trial expires.

Firefox is (and was) my default web browser. The software and updates for firefox have always come from your official website and in a timely manner.

Could you please look into and resolve this issue?

Thanks so very much for being Mozilla Firefox!

I'm using 64-bit Linux Mint 20.3 LTS, and the latest version of Firefox from the repositories (101). Suddenly, for no reason I know, my default profile has started crashing immediately on trying to run Firefox. A small window comes up with the error message

XML Parsing Error: not well-formed Location: chrome://browser/content/browser.xhtml

     <button when-cofnection}"secure-cert-user-overridden"="" <="" pre="">

and then a line of ------^ where the ^ indicates between the t and the i of cofnection

Yes, I emphasise that I HAVE copied the error message carefully, including the mismatched bracket pair and the cofnection rather than (I assume) connection

I've managed to get a working version of Firefox by creating a new profile and using that (as in for posting this request for help), and I do have a recent backup of my bookmarks, but it will be a royal PITA if all my logins and passwords have disappeared. I don't want to go any further than this without some guidance, as all the messages I've found detailing how to fix this seem to make the assumption that I'm running Windows.

Can anybody help, please?

I routinely record short screencasts with Kazam, and I can't watch my own videos after posting them on sites like GitHub because Firefox says "Video can't be played because the file is corrupt". Or for example when I upload them to sites like ezgif to convert them to a GIF, which works just fine because, well, the file is not corrupt. Other browsers like Chromium play them just fine.

Apparently the "OpenH264 Video Codec provided by Cisco Systems, Inc" is properly enabled in my system. This has been happening to me for months or years, but only today I decided to open a thread here.

There are two things here:

1. Firefox can't play the file. I'm sure there's some sort of misconfiguration on my side, or bad defaults, or a missing plugin, or similar. 2. Firefox shows a misleading message. The file is not corrupt! The root cause is something else.

Any advice on how to fix the first one?

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

Hi, my Firefox on Win10 doesn't work, I've been forced to go back to Chrome. After a crash in Win10, Firefox doesn't work anymore: it opens, be it launched by me or by other programs, but it just sits there, blank, doing nothing. It is impossible to interact with menus and everything. Task Manager shows two open instances of the browser, using RAM, but the browser doesn't do anything. It doesn't "crash" and it doesn't freeze, it just stays like that. If I quit it and try opening it again the PC tells me it's open already, and Task Manager shows a couple instances staying there after quitting it, as if it stayed stuck. I tried resetting it from the Apps settings of Windows, but nothing happened, I tried uninstalling it and then installing it again, but nothing happened. Restarting the PC a couple of times changed nothing. In the end, I had to go back to Chrome and even put it as default browser because all programs were calling up Firefox which stayed unresponsive. Anybody knows what I should do in a case like this?

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

  • My mail client is completely unaffected and is behaving normally.
  • I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
  • Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

Just paid $150.00 for a remote session from my computer store. Advice is: My older computer (2004)and it's graphic capabilities aren't compatible with newest FF. So I'll stick with older version (9) until I decide to get new computer. Firefox is my preference, but if I update, it's likely to break again. Please tell me how to stop all update notices. It is maddening. Or, if you can do it, please do. I don't want to use the others. It has crashed twice, just FF, in the last few days. A system restore saved me, but I updated and lost it. Can you help this not wealthy person? I thank you for your fine product, and your help.

In Firefox, my instructor and student grade sheet no longer displays the horizontal scroll bar to bring more data extended off to the right of the page into view. I have an image attached where the scroll bar should be present. This begin in May sometime, and I'm not sure how to fix. I have tried re-installing fresh a few times, and removed any custom settings that might have been in place. Any and all help would be VERY appreciated as one of colleagues is super frustrated and I would love to find out an answer for both him and myself.

I also found that some internet pages work (display english text) and some do not - I have logged a ticvket with ASUS but is anyone able to see an obvious difference between the following URLS These URLs were on the on the Firefox startup screen default webpage Note that Show source of all these pages only shows boxes with numbers in them as well so I can't clearly see on the ASUS what the difference is

The following did not work

   https://www.amazon.com?tag=admarketdeskt-22<tracking>...

but I tried https://www.amazon.com?tag=admarketdesk and this was fine - so then I refreshed the full URL with the tracking tokens - and it was working as well

The following do not work That is they display boxes with unicode values

   WikiPedia - https://www.wikipedia.com
   Facebook - displays boxes with unicode value https://www.facebook.com

The following work with proper english text

From time to time I get an Error Overflow message in Firefox. Sometimes I enter the website directly in the address line and other times I click a link in an email and it tries to open in Firefox as it is my default browser. If I copy the address line to Chrome it loads correctly.

This is mildly irritating as it puzzles me each time it happens.

I have attached a screen snip showing the error.
