Hi furydeath9, Is Firefox still running in the background when it is closed? After closing Firefox, wait a few seconds. Then, right-click on the taskbar and select "Start Task Manager" from the context menu to launch the Task Manager. If you see Firefox listed right-click on it and select End Task.

Either way, I recommend running a malware scan. Malwarebytes Malwarebytes AdwCleaner

This time it happen i never open firefox after starting my PC. I got a random firefox failed to open pop up would you like to start in safe mode? then about 4 hours later I had the two pop up's saying firefox had crashed and not once have I even open it yet.

Hi furydeath9, Be sure Firefox is closed and not running in the background when you run malware scans.

Nothing, cause it's firefox causing this. Just restarted and it pops up

"Firefox is already running, but it not responding. The old Firefox process must be closed to open a new window"

10 seconds later it say's it crashes. So WHY IS FIREFOX trying to run at boot up.

THis one at least was sent so i can share the crash report.

Firefox works fine, for now, when i close it after opening the first time the prcess is killed but it's just the start up that seems to be causing all the problomes for some reason.

Reboot the computer. Then open the Windows Task Manager and make sure Firefox is not running, Is the problem still there?

Note: Firefox cannot start itself, but other programs can call it.

Please post the crash reports for the last 5 - 7 days. +++++++++++++++++++++++ If you can't get Firefox to open, you will have to do this the hard way.

yep now if only it said why it's running at boot up and then crashing

Open Windows Internet Explorer. Have it declared as the default browser, But turn off the option to check this when the browser opens (If you want).

so just stop using firefox sounds like a great idea.

Seems it's just NVIDIA Web Helper.exe cause it's always NVIDIA also had an error saying NVIDIA Web Helper.exe can not run cause it's missing a file

Try removing, then reinstalling NVIDIA.

Even with out drivers i used the Display Driver Uninstaller in safe mode. Firefox is STILL running at boot up with. Trying to open it cause it to say it's already in use and then a crash happens.

furydeath9, Take a look at this: NVIDIA Web Helper.exe virus

I read abuot that but everyhting it says to Type about:addonds on the address bar.

Yet that doesn't work with firefox.

Think I found what was causing it. I saw mozilla maintenance service was in the program list uninstalled it restarted and no firefox in the precesses list at boot up or crash pop up.
