I had most updated versions of Mozilla Firefox in my windows 10 machine. last two days, it is not opening. Tried several recommendations from Community page, Help documents and youtube solutions but nothing seems to be working.

  • Tried re-installing firefox, by downloading the latest version from Mozilla, after deleting the profile folder (%APPDATA%)
  • Tried removing the cache files / temp files etc., and restarted as well, still did not work.

I do not have admin permission hence could not open in windows safe mode.

Any suggestion please?, Appreciate your input!

How do I completely remove all traces of Firefox from my windows 10 OS? Note: This is why, After windows ask me to run your application or program or software, and I click the yes button after I had done that it doesn't do anything after that and then it just repeatedly does this, and I had used windows uninstall program and I uninstall Firefox then I had reinstall it and it still did the same exact thing that I had mentioned above "even tried using the Windows Registry Editor too!"

Note for years I had used your browser and hardly had any troubles with or problems with your browser

10/20/20

I clicked on the update button last night - running 81.0, and the update was for 81.0.2. When I went to open the browser all that I got was a line at the top - FF would not open. I backed up the profile, and did a clean install. When I finally got the backed up profile installed, it opened properly once and everything was there. When I opened it again, no book marks, and none of the buttons worked. FF didn't close properly, and I had to use Task Manager to shut down.

I ended up downloading the beta version, and it's worked just fine. The original profile works, so all bookmarks are there.

I see that FF released 82.0 this morning. Is it safe to try to install it, or is the beta version that I installed last night really 82, just hours before it was officially released?

Am trying to take an online assessment for a job. I’m getting - Error: Firefox can not see the cpu or ram on this PC. I’m running win 10 64bit and have the latest version of Firefox installed. I’ve turned off thumbprints, added the site as a trusted site and pretty much killed all security for this site. How can I let FF see the cpu/ram?

Hello! I've been using Firefox for years now, and just recently set up a dual boot system with win10 and kubuntu. I've never had this problem with Firefox before, and it's only a problem on win10. When I open Firefox, there's only blank white where a page would normally be. Trying to right click brings up nothing. I can open the menu, but things like options, add-ons, customize, etc. all do absolutely nothing when I click on them. When I click on the icons of my extensions in the upper bar, the extension interface is empty as well. Nothing changes when I try to load a page--Using the search bar causes a spike in my otherwise flat ethernet usage (I dont have any other processes running that use it while im testing this, but just to cover my bases I can access the internet without any issues on discord or other online applications.) The search bar does retain what I searched. Rather than becoming about:blank, it just becomes, for example, "https://www.google.com/search?client=firefox-b-1-d&q=test" Other browsers work completely fine. I've tried doing a completely clean reinstall (deleting files in ProgramFiles, %appdata%, the Old Files folder that is created during an uninstall, and uninstalling using the apps and features menu.), using DISM to check for anything wrong in sys32, opening Firefox in safe mode, opening it as an administrator, disabling any firewall or antivirus i can find, and deleting my Firefox profiles. Nothing has changed anything at all. Please help! <3

My laptop died - but have FULL back up on ACRONIS cloud ... I want to find & restore my Firefox BOOKMARKS/ favorites etc. FIREFOX creates a PROFILE that contains all the data... BUT its hard to find!!??

I know location is USERname>AppData> Roaming>Mozilla>Firefox> PROFILES

BUT ... on my NEW Laptop when I go down through C:Drive hierarchy I cant see "AppData" If I search I can find ... BUT I cant actually locate via USER NAME.... Is this to do with HIDDEN FILES???

So when I go to my CLOUD BACKup I have the same problem. I can search & see ...but cant find in the hierarchy so I can recover those files & re-install on my new laptop... Any ideas where these hidden files are located?

Any ideas?

Thx for any help Cheers Keith

Microsoft/Windows 10 has removed Firefox from their list of potential default browsers. Most information answering "how to make Firefox my default browser" is out of date as the information says to go to where Microsoft Edge is noted as the Windows 10 system's choice of default browser, then to click on that and choose Firefox from the choice dialog box. Sadly Firefox is no longer in that choice dialog box. Please advise, thanks.

hello, i have a Raspberry Pi 4 with 4GB and Raspberry Pi OS installed. (2020-05-27-raspios-buster-armhf.zip)

when i use the stock Firefox ESR (installed via sudo apt install firefox-esr) and watch videos (e.g. on Youtube, Vimeo, ...), Firefox does crash some times. according about:crashes, i already have submitted about 60 crash reports.

but watching the reports one thing is missing. when i open firefox from the console i can see some output, that is not appearing in the reports.

... firefox-esr: /build/firefox-esr-RgOFaD/firefox-esr-68.11.0esr/media/libcubeb/src/cubeb_alsa.c:1255: alsa_stream_get_position: Assertion `delay >= 0' failed. ExceptionHandler::GenerateDump cloned child 3366 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Failed to open curl lib from binary, use libcurl.so instead Firefox ESR crashes when playing videos on Raspberry Pi OS (Debian)

during watching videos in firefox there is more different output to see that seems to be harmless. but always and only this line is printed to console, just befor Firefox crashes: firefox-esr: /build/firefox-esr-RgOFaD/firefox-esr-68.11.0esr/media/libcubeb/src/cubeb_alsa.c:1255: alsa_stream_get_position: Assertion `delay >= 0' failed. so i assume this is the main reason, why Firefox crashes on my system.

any idea how i can get these issue fixed? at the moment when i want to watch videos reliable i am be forces to use the external VLC Player by copy the url to VLC - at least for Youtube videos. but i want to watch videos from other web pages as well and i prefer to watch videos in firefox directly.

I just upgraded to Firefox 77, x64, Windows 10 2004.

Firefox 76 already broke LockWise - https://support.mozilla.org/en-US/questions/1287008

Now Firefox 77 breaks 99% of all websites. (See attached screenshot.) www.example.com www.google.com www.wikipedia.org etc

Somehow, support.mozilla.org works, UNTIL I try to log in.

I've tried incognito mode, safe mode, etc. When I change charset of the page, the text displays differently, but it's still a useless mishmash.

--- BUT --- when I open developer tools, click the HTML request and click the Response tab, the HTML renders correctly there.

I've been using Firefox for years most recently on a Windows machine but I've just switched back to a Mac. I'm having issues with bookmarks and I'm doing what I've always done but now am having a couple issues so I don't know if it is due to switching systems or if I have an issue.

In any case... I like my bookmarks in the toolbar so that is where I aim to put them. I exported my bookmarks from my PC, imported the file and thought I was fine but now I see that not all of the bookmarks are there in the toolbar, most are but not all. Then when I check the recently bookmarked, the missing ones are listed among the others but do not appear where I can find them.

Then I exported from my work PC to a file as before, imported the file and can not find any of them anywhere, keep trying and can't find them.

And now while on a page I click the blue star as I always have, have it pointed to the toolbar folder, click done, check the toolbar and not there. Keep trying and during the process I see an option to remove 3 bookmarks next to option DONE, so I suspect it is something I'm not understanding but on my PC I've never had issues with this.
