I have downloaded the "latest version" of Firefox to my Mac which is running macOS Catalina Version 10.15.3. After 7-10 days Firefox will not "open". I then uninstall it, and reinstall it. Again it works for 7-10 days then will not open at all. I have gone through these install / uninstall processes at least 10 times. Yet after 7-10 days Firefox will not open. What is causing this, and how can I keep Firefox working continuously on my Mac? Thank You. WA

P.S. - I am sending this question from a Windows 10 computer because I cannot open Firefox on my Mac.

Hello, The day before Firefox just stopped working, I can start the program but its completely disfunctional. Menu bars roll down, but if I click on anything, nothing happens, like if the buttons were dead. External buttons like "open file", "save page" do pop up, but not internal ones, like Troubleshooting info, probably because they would also open as a Tab, which doesnt function. I can type into the search bar, shows the url, even seems to have access to search suggestion from Google, but nothing happens at all. I tried everything I could find, reset Firefox through safe mode (also doesnt work better), completely deleted and reinstalled everything, including all data folders, checked my Antivirus (Norton... yes, could be bad), but I even deinstalled antivirus. Also tried "netsh winsock reset" https://support.mozilla.org/en-US/questions/1021896 Im out of options. Thanks for Help!

I have reinstalled FF a number of times after deleting Mozilla Firefox folder from Program Files Folder. After running the setup 74.0.exe file, FF loads and I use it repeatedly during the day. Next day the same problem occurs "couldnt load XPCOM". I did add Mozilla Firefox to my Malwarebytes Allow list, but no effect on the problem. Any help is appreciated. Richard rrbryant@mst.edu

Alright, so I've tried installing a previous version, deleting all files in Local, LocalLow, Roaming, and Users/Program Files related to firefox, even deleting registry keys, but every time I try to use firefox I just get a flickering loading circle on my mouse. I open task manager, and see that firefox is in there, and constantly opening and closing new processes on itself. I try to kill the process and cannot as whatever one I'm trying to close is already dead and a new one takes its place.

Catalina (10.15.3) and Firefox (73.0.1) aren't working together. As soon as I stop actively using Firefox it crashes. If I try to reopen it, I get a message that I can't reopen it because there is a copy in use already. If I try to force quit Firefox it is not in the force quit menu. If I look in Activity Monitor Firefox is not present there either. Thank you.

First, I just had a major system crash, had to re-install Linux Mint and through my own stupidity, relied on the wrong backups for my firefox configuration. So I lost my Firefox 52 install with all of my extensions (that still worked). Now, I'm running v. 57 Quantum, and a few things aren't working correctly.

First, the MAJOR problem: when I open a link from a bookmark, it's clobbering an existing tab that I was using (that's why it was open, obviously). That is completely unsat and can not be allowed to continue. How do I correct this? I can't find the option under settings-->tabs to fix this problem.

Second issue (major annoyance): I can no longer create a bookmark directly in a bookmark folder on the bookmark toolbar. I used to be able to open that bookmark folder, and the first option was to bookmark the currently open tab. That option has vanished, and i use that all the time. How do I restore that?

Actually, one more issue: I have two tabs that are pinned and are supposed to be protected (i.e., nothing can clobber them, and I can't close them without deliberately turning the protection off (context menu right-clicking on tab). I need that back, because for some reason, firefox thinks it's ok to open a bookmark in those tabs, too, when it most definitely is NOT ok.

Thanks, Jim Graham

Every time I open Firefox it brings up a screen as if I am a brand new user starting out for the very first time. The disk image in my downloads folder has long since been deleted, so I'm pretty sure it's not running from that. I went and looked at "application binary" and it gave me a headache, plus there was no indication in the prior "support" replies of what the changes I might or might not observe therein would mean, so I was unmotivated to keep turning Firefox off and on and then checking to see if any of the characters in the very long text string had changed. I seem to have about 10 profiles, none of which have been created by me on purpose. I tried opening a couple of them, and got messages about various updates Firefox wanted to perform, but none of the opening screens had my information loaded. I've just lost a half hour of my life down this rathole this morning, and I still haven't gotten around to completing the search which was the reason I opened Firefox this morning in the first place. Imma have to go back and use Safari I guess, since Safari isn't suffering from "Susan Amnesia"

Dear All, my Firefox is broken. It starts and shows a blank tab, but I cannot open any site, not even about:config or the options pane. Typing anything in the address bar or the search bar and pressing Return does nothing.

The only things I can do is opening new tabs (which will remain blank), and clicking on menu items in the main menu. None of the items that would open any dialog works, though.

So far I have tried:

  • Starting Firefox in safe mode
  • Creating and using a new profile (firefox.exe /p)
  • Uninstall FF and re-installing the latest version
  • Uninstalling FF and installing a previous version (downgrade), using a new profile
  • Deleting all mozilla and firefox entries in the registry in an uninstall / reinstall cycle

Now I am out of ideas. Any help is welcome. Thanks!

I have been having problems with firefox lately. Every time I try to run the program it automatically closes without giving an error message. I am running Windows 10 and this happens in safe mode as well. I have tried doing a clean install of firefox - that did not fix the problem. I tried deleting my profile after uninstalling then doing a fresh install, this did not fix the problem either. I ran a virus scan and did not detect any malware. I don't know what else to try.

Firefox updated yesterday and ever since then it will not open at all. I am running the latest macOS on a MacBook Air. It just bounces on the Dock once then doesn't open at all. I have tried uninstalling and reinstalling AND I even tried to downgrade back to 70.0.1 and it STILL didn't work. It won't even open in Safe Mode.

My version of Firefox is 71.0 (32-bit). I tried to reinstall Firefox (did not help), I tried safe mode ( did not help). I tried to disable and enable hardware acceleration (did not help). Firefox just CLOSES by itself, and there is not crash reports. Is very annoying. Did RAM test- everything is ok. GPU drivers are also new (nvidia).

Flash plugin is not the problem- it was installed during this whole mess.

Non riesco più ad accedere a FIREFOX, che ha funzionato per molto tempo. Ho già contattato l'assistenza MICROSOFT che ha pulito il sistema ma non ha risolto il problema. Firefox assistenza dice che ci potrebbe essere interazione con programmi antivirus,antispyware,ecc.. Provare a configurare il firewall utilizzato per capire se il problema si risolve. Il problema è il seguente: Firefox non si avvia perché dice: FIREFOX è già avviato, ma non risponde. Il processo esistente di Firefox deve essere chiuso per aprire una nuova finestra. CHIUDI FIREFOX---- HO PROVATO A DISINSTALLARE FIREFOX ed a eliminare da GESTIONE ATTIVITA' il file FIREFOX.EXE -- HO REINSTALLATO FIREFOX - SI E' RIAPERTO MA POCO DOPO E' TORNATO LO STESSO PROBLEMA. HO RIFATTO LA DISINSTALLAZIONE E LA REINSTALLAZIONE ED IL PROBLEMA E' RIMASTO TALE. Avete qualche suggerimento ? Grazie
