downloaded firefox but not running

more options

new computer and downloaded firefox but is not opening. tried to delete it but won't let me as it says firefox is running and I need to close it before it will uninstall. It says it is running but I can't find it, can't open it and can't uninstall it. Now what and how do I find it if it is running?

Do you have the Firefox icon on your quick launch? Close Firefox. Right click on the icon and select Open New Tab/Window. Sometimes this works. If it opens, close it by Menu > File > Exit.


This is not a cure but will make it easier if Firefox locks up in Windows. https://support.mozilla.org/questions/997866 {web link}

Use another browser, download the FULL installer from

https://www.mozilla.org/en-US/firefox/all/

Check your system requirements (just in case to be on a safer side)

Save the file. Then, open the PROGRAMS FOLDER and discard the OLD FOLDERS and run the full installer.
