Firefox version: 102.0 (64-bit) System: Windows 10 21H2

I recently downloaded a file that may have had some sort of virus or malware. The file came up negative in Windows Defender and Malwarebytes but I deleted it anyways; however, I still get a download popup every time I open Firefox telling me that "This file contains a virus or malware." I've cleared the download library and browser history (cookies, cache, etc.) but I still get the popup from the Firefox.

Is there any known fix for this? Thanks!

The rendering issue is not seen with Chromium (Linux) or Safari (Mac). I have no alternative for Solaris :-(

I have read the tips etc, reset everything, but there is no difference.

This has been happening for a a couple of years, getting progressively worse, It has got so bad, I have stopped using FF on all but Solaris now. (and I have been using it for a long long time).

I need someone to direct me to what information/data is needed to be collected so someone can comment. Do you have any favourite page load test web sites that I can send out put to you from?

At random, whenever use a search box on a page, Firefox will lock up. The "loading" icon on the tab will animate as normal, but the entire window won't respond. If I press the show desktop button and then try to reveal Firefox, none of the windows will appear. I'd have to go into Windows Task Manager and be lucky enough to terminate the correct process containing the tab, or else I'd have to start all over again.

I have W10 fully updated with plenty of RAM but in the last few weeks, after I boot up in the morning (I shut down every night) it takes a long time (several minutes) for either Firefox or Thunderbird to fully boot up . Firefox opens tomy home page, but does not complete for several minutes so I can go nowhere. If I am patient and wait it is fine the rest of the day..nice and fast. If I shut down and reboot again- very very slow opening of both for the initial time. I have run full virus scans, sfc/scannow, malwarebytes, cleared history and cache and cookies, turned off and on hardware excelerator. Any other suggestions? Word and Excel open quickly as usual.

The latest update for Wondows 10 prevents Firefox (and Edge) from loading. Everything works fine once I've uninstalled the latest update so the problem is clearly theirs. I can't be the only person experiencing this problem but contacting Microsoft is next to impossible. I wonder if you can: 1) alert them to this issue; and 2) pressure them to fix it as constantly uninstalling the updates is a pain!

Hello, My firefox has been randomly exiting for a longer time now. (I reopen Firefox it restores itself without any crash info) I've already tried reinstalling and using the cleaning tool. Now I wanted to remove my Addons, but one of them isn't deletable. It also has no name displayed which confused me... Furthermore, there are only "InstalTime12345678"-files in the crash reports directory (which I think aren crash reports). It seems to me the mysterious addon is installed through the policies. (I have a screenshot attached and uploaded them https://pastebin.com/59wzMDyv) This is my private computer and I never set those. Has anyone seen this before or can help? Thanks

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

Firefox 101.0.1 + extensions, Windows 11 22H2; both fully updated

Firefox has stopped saving the position of its window, looking to me like it is leaving space for my Windows taskbar but which is hidden.

Some online searching and I found that setting privacy.resistFingerprinting to false resolves the issue, but it is not a change I feel comfortable with and wonder if there is another solution. I have uBlock Origin installed so maybe I shouldn't be concerned.

I'm not sure if this is the cause but a few days after windows update my firefox crashes. I restart it and only screen opens and doesn't respond. Deleted Firefox, did fresh install. Firefox starts again but as soon as I log in my account, crashes again. Delete firefox and again fresh install. I don't login, I save 3 bookmarks and it crashes again. Delete firefox again and fresh install. But now firefox starts in the background (seen in task manager) but does not open a window. Download latest installer and try to install but now install says, "something went wrong" during the download. (could be the enterprise network here) this I tried a few times but no success.

So I download Firefox 101.0.1 ISO and install. But again running in background and no window.

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

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.

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?
