I work in IT and multiple users are having this same issue. It seems to have started at the same time about a week ago. When clicking on Firefox, no window opens and the cursor begins to rapidly flicker or spin. There is no error message given. When checking Task Manager, there are multiple instances of Firefox running. Trying to "End Task" on each instance proves futile because it seems that they are constantly refreshing (which is probably why the cursor flickers). Trying to run the command "taskkill /f /im /firefox.exe" sometimes works and sometimes doesn't, even in Administrative mode. The only sure fire ways to get the cursor to stop flickering and/or close the program is to restart the machine or uninstall Firefox. However, if Firefox is clicked on again after restarting, it goes back to flickering and no window ever opens.

Things I've tried:

1. Using "End Task" in Task Manager

2. Running CMD and using taskkill /f /im /firefox.exe multiple times.

3. Restarting the machine.

4. Clearing ALL temp files from the machine.

5. Uninstalling and Reinstalling Firefox

6. Uninstalling, deleting Mozilla folders from Program Files, Program Files (x86), and Reinstalling

7. Checking to make sure Firefox is not blocked by the firewall or anti-virus.

8. Uninstalling, deleting Mozilla folders from Program Files and Program Files (x86), Deleting Profile data from AppData\Local\Mozilla\Firefox, then Reinstalling

Nothing seems to be working. Any ideas?

Firefox has opened successfully for years. Today, I double clicked on the icon, and it will not launch. I uninstalled and reinstalled it two three times and no luck. So I then tried performing the profile creation and got the following result.

Profile couldn’t be created. Probably the chosen folder isn’t writable. [Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIToolkitProfileService.createProfile]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)" location: "JS frame :: chrome://mozapps/content/profile/createProfileWizard.js :: onFinish :: line 181" data: no]

Not sure how to solve this.

No matter how I close Firefox, (X, File->Exit, Menu->Exit), if I start it again it doesn't automatically restore the previous session.

If I click on "Menu->restore previous session" it does restore it.

Of course "Restore previous session" is enabled.

Why did it stop working, what changed?

this morning, I get the above error message when attempting to open ff. I was able to open ff from the start menu(windows 7 enterprise), but all of my bookmarks have disappeared. I had the system administrator attempt to restore my computer, with no results, then reinstalling ff. upon reinstall, I was able to open ff, but bookmarks were still missing. then, a ff update "esr" was run, and now I get the error msg above trying to open ff from anywhere. I cannot open ff at all to restore defaults or run in safe mode to fix.

I set google.com as my homepage and haven't had problems until today. When I opened Firefox, The Microsoft homepage opened. I tried refreshing Firefox, checked the URL in Properties, and looked for add-ons--no fixes. The refresh had no effect, there was no URL added to the firefox.exe in properties, and I have no add-ons that would cause this. I thought it could be a virus but the page seems to be a legitimate Microsoft site. If I click the home icon on the tool bar, I get to the correct page. I'd appreciate any suggestions you might have. Thanks

Firefox crashed on me yesterday (2 Dec 2018) and does not open at all now, so Safe Mode is not an option.

Have tried: (1) closing and restarting Firefox; (2) restarting computer (MacBook Pro, Mid 2014, OSX 10.13.6); and (3) trashing Firefox, emptying trash, and restarting computer again. No luck. Continue to get the same, "We're sorry. Firefox had a problem and crashed," error prompt.

Per the instructions at https://support.mozilla.org/en-US/kb/firefox-crashes-troubleshoot-prevent..., I am pasting my most recent Submitted Crash Report here: Crash ID: bp-550e8b76-0c74-487f-a901-7abc70181203

Any help would be appreciated.

Thanks, Brandon

Firefox won't open and only gives me the crash reporting window. I'm on a mac with mojave (this started about a week after that was installed). I have tried starting in safe mode, creating a new profile, and multiple fresh downloads and installs. Nothing works. This has been going on for a few weeks.

The last crash report only says "1543632621". Previous crash reports are similarly empty with only a number.

Hi, I have a Mac 10.11.6 and for whatever reason I cannot get Firefox to open. I received a message at the bottom of my browser during the last use saying something to the effect of click restore/restart to improve speed. I did this and now Firefox will not open. I get a Mozilla crash reporter screen even when I try launching it in safe mode. I tried the refresh option (by holding shift + option on startup) and still get the crash report screen. I reinstalled it multiple times, tried deleting it and doing a clean install, deleted my profile and created a new one, and even deleted my anti virus program. Nothing seems to be working and I am very eager to get my preferred browser working again.

Thanks very much for your insight!
