Firefox window will not open, programs are still running in Firefox
When I try to open Firefox it will not open. When I did end task Firefox was removed from task manager but still would not open. Turning off PC did no good. I even tried to uninstall so I could reinstall but could not uninstall because program still running. I have run out of ideas. What should I try next?
I found two different versions of Firefox on my PC. I was able to uninstall one version then the other that I was trying to uninstall earlier then reinstall Firefox.Read this answer in context 0

What's your computer system and Firefox version?
It's possible that the Firefox window is opening outside where you can see it. Try this; Open Firefox. After it opens, wait a few moments. Then mouse to the Firefox icon, right-click and select Open New Window. If this works, close the first icon.
I've tried that several times and will not even open new window. I'm considering a restore on my PC since it's only 2 mouths old and I have everything backed up.
It could be a Firefox issue or there are some virus/malware that causes it to not close and keep running.
