I have been using Firefox for years. I just downloaded your newest version. The new version shows to be downloaded successfully, but when I click Firefox Icon, I get a window that is called "Offline mode"
It states, "Firefox is curerntly in offline mode and cona't browse the web. It says to uncheck the "work offline" menu item.
- File > [ ] Work Offline
Press F10 or press and hold the Alt key down to bring up the "Menu Bar" temporarily.
