Firefox is already running but not responding. The old firefox process must be closed to open a new window
Hello Team, Firefox is already running but not responding. The old firefox process must be closed to open a new window. I'm running a windows 10 laptop. I tried to resolve this issue 1) through task manager, but the issue didn't resolve mentioned in the browser 2) Remove the profile lock file, but it didn't show any folders/files.
However I'm able to install and use other browsers like edge, chrome and opera. Can someone help me to resolve this issue and use firefox browser?

Have you tried rebooting the computer? https://support.mozilla.org/en-US/kb/firefox-already-running-not-responding https://www.basezap.com/cant-open-firefox-because-a-copy-of-firefox-is-already-open-mac/ https://apple.stackexchange.com/questions/196771/cant-open-firefox-because-a-copy-of-firefox-is-already-open http://kb.mozillazine.org/Firefox.exe_always_open
Hi FredMCD Thanks for sharing these resources. I did try them especially the first one, but didn't do a system restart. I don't know what's the issue, but after installation of a new antivirus software the problem was solved, and the previous free antivirus software and the new full-version software didn't show any sign of virus/trojan horse infection. Now I'm posting this message from firefox.
