I've had Firefox installed and working in W-10 for a long time, yesterday it suddenly got minimized to the task bar and nothing I tried would open it. I had to use Chrome to search for advice, and it turns out that other users had the same problem. I tried the suggestions (alt-spacebar-move) etc. but nothing worked. I had to got to "Uninstall" and the opted for the "Refresh" function to restore Firefox to a functional Browser. It's now working again, but what caused it? and is it likely to happen again? Thanks for your attention  :)

Close Firefox. Open your file browser to this hidden location:

  • Mac: *~/Library/Application Support/Firefox/Profiles

  • Windows: %AppData%\Mozilla\Firefox\Profiles
  • *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
