Firefox supportforum

Hi all, I just got the update to 76.0.1. Now, Firefox Always crashes right after starting it - even in safe mode. The only notification I get is (in German) "Firefox funktioniert nicht mehr. Ein Problem hat die richige Ausführug dieses Programms verhindert. Schließen Sie das Programm" Please help!!!

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

Hi ---- Wondering if anyone can help with this. Every time I open Firefox (my default browser), I get a spinning wheel, the browser doesn't load and my whole system crashes.

I have tried reinstalling Firefox - same problem occurs. Anyone got any tips? I'm running a mac on El Capitan and have been for a while with no browser problems.

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.

During class today, Firefox unexpectedly crashed on my Windows 10 PC after downloading a pdf file from my History teacher. Now, when I try to open Firefox, a transparent box quickly appears before disappearing again, not opening Firefox. I have yet to find a solution that has worked.

I opened Firefox this morning and used it for about half an hour. I can't remember why I closed it (or IF I closed it) but when I attempted to reopen I got a blank screen attempting to open my Yahoo homepage, but nothing happened. I force quit and attempted to reopen and nothing happened. I'm on a iMac and the icon on the deck just keeps bouncing. I haven't changed anything and it worked fine earlier. Is there a system problem? Thanks.

Over the last couple of days we are seeing instances of Firefox just disappearing from Windows 10 and just today from a Windows 7 pc. When I say disappears, the desktop shortcut becomes dead, click on it and a prompt to search for firefox.exe comes up. Checking Add / Remove programs shows Firefox to be installed. Checking C:\Program Files\Mozilla Firefox reveals empty folders with the exception of a couple of text files. Trying to reinstall the Firefox app, we are prompted with a message that Firefox.exe can't be found, and there is a button to browse for it. The only solution we have found for this is to copy the C:\Program Files\Mozilla Firefox folder from a working pc, and we just received a call from a user we did this for telling us that it is gone again. Any ideas?

Thanks.....

We have checked for viruses.

Hi there,

I have a brand new Win 10 MS Surface 4 Laptop, and have tried downloading and installing various versions of Firefox:

From the the Windows Store Direct downloads (via MS Edge): Mozilla FF Win 64 Mozilla FF Win 64 MSI Mozilla FF Win 32

I have completely uninstalled and attempted to re-install each in turn. Attempts to open FF through desktop shortcut, Start Menu and Win-R FF.exe all seem to start but only ever get the briefest flash of a blue line along the Taskbar then nothing. Same happens starting Shift-Shortcut.

Nothing shows in Task Manager either after any start method. I'm pretty sure I'm not in 'S Mode' as I've been able to download, install and run WhatsApp Web, but I'm not wholly convinced I've cleared that up fully.

Thanks! E

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.

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

More than 3 years I start firefox with a command line, "rm -rf /Users/mr.suradetc./Library/Caches/Mozilla/updates/Applications/Firefox/updates/;/Applications/Firefox.app/Contents/MacOS/firefox". I have been updated mac os x from Sierra , High Sierra,Mojave and now Catalina but every os, I still got the same problem.

I've been experiencing too much crashes on Firefox 75.0, downloaded from Mozilla, not the one that comes with Linux. I'm running on debian9 on Qubes OS but I also experienced crashes on Ubuntu 19.

It happens mainly when I switch tabs. I'm asked to restart. I already submitted hundreads of crash reports, hope you guys are taking a look. However this have been happening since january I guess. And it's getting worse.

Sometimes the crash will happen again and again if I try to reload the tab. I have to close the tab and open it again so it won't crash.

Please help, I love firefox, don't want to use another browser.

Here are a few ones:

Hello all, after reinstallation my Firefox 88.0.1 on Windows 10 64 Bit does not go online. I can't open the settings. Other browsers like Opera and Edge are ok on the computer. Does anybody have any hints ? Many thanks, Volker

whenever FF requests a restart after update i click "restart" but ff doesn't restart. Has happened on both fedora 30 and 31, possibly on 29 as well. when i manually restart FF all windows and tabs are restored properly. Currently running FF 73.0.1 (64-bit) on a desktop PC with fedora 31 5.4.19-200.fc31.x86_64 with XFCE desktop with 10 workspaces open.

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
