I tried to delete browsing and web history when closing Firefox and this problem happened with Firefox immediately hanging up not closing except on 'force quit' and then totally not opening at all. It won't open in Safe Mode just zilch happening! Nothing I've tried has worked. I've removed and reinstalled Firefox, it but the same immediately happens. I am an older person and not a tech head! So need some simple instructions. Presently I am using Safari and but would like to get Firefox back and reinstalled again so I can access my book marks. Thanks for your help.

I've uninstalled, reinstalled, deleted all profiles, viewed and attempted every suggestion that was found via search engine. Firefox will only start with -P option and creation of new profile. Once closed, it will not open again using the profile just created. Any ideas as to what type of additional troubleshooting that is available. There are no crash reports or logs generated anywhere that can be found. Running on Windows 7 Professional.

I was using Firefox without problem until the last few weeks on my 3rd Gen Carbon X1 running fully-patched Windows 10 64-bit. At some point, it just stopped launching. I have tried everything suggested here https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions without luck.

In particular, I uninstalled Firefox with Windows 10 "Add and Remove Programs". Then I deleted all Mozilla/Firefox folders under \AppData. Then I went through the registry and deleted every Mozilla or Firefox key. I rebooted, and reinstalled Firefox from scratch using the installer. There are no errors on installation; however, when I then try to launch Firefox, nothing happens (the process is visible in task manager or pslist, but otherwise no windows opens). I have also tried launching firefox.exe from the command shell; likewise, no errors or other response--it just stays spawns the pid but then no window opens or other visible indication that Firefox is there.

I've tried variations on this uninstall/purge/reboot process several times without any progress. I just can't get firefox.exe to launch at all on this system. Otherwise, the box seems to functioning perfectly, and all other common web browsers work fine.

I've also tried launching in safe mode (via command line or keypress) but get no different result.

Any ideas for narrowing the issue?

This happens even when I set my homepage to something different.

FF 58.0.2 64-bit Windows 7 64-bit

My home page is

http://www.weatheroffice.gc.ca/city/pages/on-118_metric_e.html

Frequently, when I open FF, I get the following error:

"Page Not Found (HTTP 404)

The page requested could not be found at this location.

If you navigated using a bookmark, we suggest you delete it or update the bookmark pointing to this site"

However, when I highlight the url in the address box, copy it, then paste it into a new tab, the page opens. The address is exactly the same in the new tab as in the one giving the error message.

I've scanned for malware, rootkits, viruses - all for nothing.

I've uninstalled and re-installed FF - no change.

Can anyone advise what else I can do, please?

Frequently when I re-start Firefox (it seems to crash about once a day), the firefox exe process hangs with NO I/O. Firerfox does not even get to the point of asking me if I really want to start in safe mode. I tried getting a dump via the Task Manager, but taskmgr tells me "permission denied". Attached is a screen capture of the latest occurrence. This is the latest FF 46.0.1 on Windows 7 Professional 32-bit.

iMac running 10.13.4 (17E202)

Uninstalled old Firefox by dragging to trash.

Restarted.

Downloaded latest Firefox from Mozilla site.

When I click new install to open, a window launches, but nothing else happens but a continuous spinning wheel. Eventually, nothing for it but to force quit (and force quit window confirms Firefox is "not responding").

What should I do?

Firefox suddenly stopped working today. When I open it, it tells me that it's already open (which it isn't) and that it can't find or load my profile. If I go directly to profiles and create a new one, I can open it, but all my bookmarks are gone. And then if I close and try to reopen it, the same thing happens--I can't open it and get the same error message.

One thing I figured out is that the profile can’t be read only, and I discovered that mine was (why I don't know), but when I try to uncheck read only, it instantly reverts back to read only, which is weird.

I’ve tried reinstalling Firefox several times, but it’s always the same, even with a brand-new installation, I can’t open it and get the same error message. What can I do if reinstalling doesn’t even work?

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?

I'm getting a blank (white) screen when my Win 7 pc boots up to the desktop (see attached screen shot). It has a small FireFox logo at the upper left corner. After about a minute this window will close revealing the desktop. If you try to close it, it says it isn't responding. As a test, I uninstalled FF and then rebooted. This window didn't open up. I can't tell if it is a FF issue or if some program is trying to use FF on startup but failing. Has anyone else had this issue?
