I have downloaded Firefox on Windows 7 but it will not work. It was working previously but has now stopped.
Without any warning messages being displayed, Firefox which we have used for years successfully has just stopped working. I have uninstalled it twice and each time reinstalled the latest version from the download website. However each time even with the new version installed it comes up and says a previous version is running (which we cannot see) and this must be closed first.
On running it simply puts up a "New Tab" screen with nothing in it. I have run my installed Antivirus program twice and it has reported no issues.
I do not know what to do next.

Hi, Please open Windows Task Manager, once open click on any Firefox running processes and End them.
uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 61.0.0 with a Full Version Installer
