I have a a separate version of Firefox installed from, ie. This is very frustrating, since it has my bookmarks & other settings but cannot use it and no other instance or Portable firefox installed elsewhere is usable!!.

I also tried another instance of Firefox portable I have at another location, same problem.

You can check both explorer.exe files then over at services like Virus Total to check the files for malicious contents.Ī settings in the Folder Options configuration of Windows Explorer explains the existence of two explorer.exe processes. It is a good idea to check the path first, if you see a different path for one process you may have a virus problem.
