Firefox Support Forum

The Firefox on my PC abruptly stopped working for pretty much no discernable reason and I don't know what to do. I've tried restarting the PC, uninstalling and reinstalling Firefox and nothing.

I dont get an error message. It just...doesn't start. If I reinstall it, I'm able to get the browser pulled up but then nothing on it works. It won't take me to any websites, it won't open the settings, it won't do anything. Refreshing the browser doesn't work either.

Failing that, I hopped on my phone and attempted to troubleshoot using information on this very site. I discovered that the problem might be stemming from corrupted profile data. I attempted to load the profile manager from Windows using command prompts...but that command doesn't do anything either.

I attempted to find the profile data on my computer and delete it...didn't work. I tried to reinstall Firefox to have it generate new browser data and that didn't work either. I dont know what to do and I dont know I'm supposed to fix this.

Please help, thank you in advance.

I cannot download Firefox for desktop. I get an error message in my Chrome browser saying my connection is not private. It says my certificate is not valid.

Where do I go from here?

Thanks, Denny

I was following this article https://support.mozilla.org/en-US/kb/run-firefox-chromeos

Installed flatpak and repositories but when I try to use flatpak to install firefox I get "No remote refs found similar to ‘firefox’".

I have tried following a few other ways to get it installed, such as using sudo and using sudo su but that has not worked at all.

I followed to flatpak quick setup on Chromebook guide that is linked in the above help article and created the nested containers in crosh as well.

below is what happens if I go to flathub and copy-paste their recommended command to install firefox.

Remote ‘flathub’ found in multiple installations:

  1) system
  2) user

Which do you want to use (0 to abort)? [0-2]: 2 error: Nothing matches org.mozilla.firefox in remote flathub

The bar that contained those items disappeared in Firefox after the update to 110 I believe. I don't know how to get it back, I've searched settings. The bookmarks and all the data appear to still be there. It's been there since, I think, version .9 something. I updated to windows 10 from windows 7 about 3 months back. I noticed the change immediately. I don't even know what the bar is called. I still have my windows 7 machine since I am still trying to resolve problem with windows 10 and I'm even thinking of going back to window 7. It did the update to 109 without a problem.

HELP!!

It is probably something simple by windows is more a game machine to me. I learned computers on a GE-645 to give you an idea of how old I am.

Thanks

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

Firefox stopped openng, tried to reinstall, no response (see the screenshot) I also use Tor Browser (never any problems) and Chrome (when absolutely necessary, like when Firefox failed to connect to an external email server and for sending queries like this one because Firefox does not work and will not reinstall. )

Hello,

The sites of my bank and from the town administration made notes that my Firefox browser was old and should be updated. I downloaded from the Mozzilla site the new Firefox for Windows 10, uninstalled Firefox and installed the new one. Then again these sites noted that my browser was old. Again I uninstalled Firefox completely and then I found out that ALL the files were not deleted but some kind of hidden. In Windows Verkenner there were no files to be found but my firewall found them all, but they had no size, no date, no digital signature at all.

Then I deceded to do a test. In the firewall I switched all the rights of the "deleted" files into "forbidden access". Then again made a new installation with the new installation file. It proceded as normal. But then it apeared that again the same old version of Firefox was present again.

My question is: what is happening here.

Best wishes and thank you, Han Benes

Hi, I accidentally DLed FF88 without checking the details w/r/t functionality.

Several of the changes severely compromise my ability to use FF for my job.

Examples are the 'view image' which is now gone from right-click and replaced with 'open image in new tab' --this disrupts my work flow. And 'save image to pocket' etc is not useful for me, but happens to be right where I normally click on another function.

Is there a relatively seamless way to undo the FF88 'upgrade' ? TIA

I am unable to download attachments from the French government website ensap.gouv.fr. With Microsoft Edge, it works perfectly. Do you know a solution for Firefox?

Every time I start Firefox, it tells me it is installing updates and will restart shortly. Why is this happening to version 88.0, which is supposed to be the latest version. It is an endless cycle.

I also use Ninite to maintain application updates. It tells me Firefox is running (although is definitely NOT) and refuses to update it.

Dear Firefox community, I do not know why you are not solving your browser-short time memory loss problem! When I download a video / file, the internet is disconnected in the middle, and it takes a while to connect, then the download starts again from 0%! It wastes both my time and the internet. If the power connection is disconnected while downloading again - I don't get any backup of that file when I connect to the internet after the power connection is restored ...! However, other browsers have this advantage. I like Firefox a lot, but this short time memory loss system bothers me a lot. I hope to fix this issue in the next update.

I'm currently in my vacation home and I don't have home internet here. I'm connecting through my mobile phone using limited mobile data. and I selected not to download updates because it keeps updating itself like twice in a week and every MB counts in limited data plans especially if it's just 4 GB total for each month.

But now every time I open the firefox it showing download latest update popup like an annoying virus on the top right corner where 3 horizontal lines are located.

I checked the internet and previously this was an option in it's settings. Then this option removed and only hidden behind the about:config . and now it's completely removed from about:config either.

The only reason I switched from chrome to firefox was because google became an absolute dictator lately and all it's changes was to limit down my accessibility. I switched to firefox becuse it doesn't backstab it's users and they give the choice to it's users rather than dictating it like dictators. So did I make a mistake switching to firefox? Is firefox becoming just like chrome now? or is there (hoping so much) and option given us to turn off the notifications as well?

... but Firefox 68 ESR is no longer available, only 78.15.0esr and 91.2.0esr. How do I proceed?

When I click on the Firefox icon to open it, the opening page is minimized and I have click the maximize button twice to get it to open to a full page. I used to just click on the Firefox icon and it would open to a full page. I cannot figure out how to change this back. Please advise.

Figured out the basic issue (from Solutions here) why old Firefox not working on old XP-SP3. Found 52.9.0esr download - but when I run the file, it keeps telling me to "Close Firefox". Used Task Manager - nothing - not Firefox or anything else - is shown to be running. Any ideas? Might not be a Firefox issue, but would appreciate any insights. TIA - Jean

Hi,

I have a fresh installation of my Macbook OS, and a fresh Mozilla Firefox installation. I would like to re-import my old passwords and log ins, but it seems that the new version of the browser doesn't have that option unfortunately. I can see only Import from Other Platforms options, but not import from file or similar.

I have .csv file, but no option of how to import in into my browser.

I would appreciate help on this one. Thank you in advance.

I bought this laptop because it had Windows 10 so I could download firefox, The laptop immediately updated to Windows 11, no way to stop it. I am locked out of my microsoft account, have been for years. How do I get firefox downloaded ?

I got an email to update to version 100, and downloaded and installed, but now I have no bookmarks or anything else, just a blank version. Please help me! Thankyou!!

My HP Omen has 2 hard drives. Originally, Firefox was installed on the C: drive and working perfectly. In order to clear up space, I tried to use the Windows Move feature to move the program from the C: drive to the secondary (and larger) E: drive. Since then, Firefox won't work aside from opening a Firefox window. It will load no pages, settings, etc.

I've tried uninstalling Firefox from both the C: and E: drives. Searched for any remaining files and deleted them. Deleted Old Firefox Data folders. I've reinstalled Firefox, without the option of where to install it, but it still fails to work at all. I get an error message regarding a missing file, VCRUNTIME140_1.dll. I've searched for the file and it's NOT missing. It is in both the Firefox folder and the Windows/Systems32 folder.

I've searched for data in the Users folders that might relate to Firefox but NOTHING seems to work that will allow Firefox to work again. I've tried putting Firefox in Troubleshooting Mode but it won't restart as it says it needs to. It just won't work!

If anyone can just tell me how to COMPLETELY remove Firefox from both hard drives so that I can just do a clean, new Firefox install, that would be preferable. I know how to import bookmarks from Chrome.

If anyone can offer some help for someone who isn't great with computers, I would greatly appreciate it. If you need any other information, please don't hesitate to ask.

Hi,

To get myself off MS Edge (as its Chromium based), I've come back to FF. But after I tried installing firefox standard and even the Extended Support Release I can not run it for the first time - I get this error

Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I've followed the advice in the help pages, but it hasnt fixed the issue

https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

The same happens when I run

firefox -p

The firefox App Data folder contains no profile file at all....
