was a strange day, the Firefox update hung and my home page came up but
my menu and title bar was blank. So I thought it was an add-on like
AdBlock or Privacy Badger, but no. It was not add-ons, it was something
Troubleshooting | Refresh Firefox a few times, manual install latest
version, the menu bar and title bar were still white and blank, I
thought, hmmmmm... Full Screen versus Normal Screen.. Press F11 and
voila, my menu and title bar appeared and toggling F11 the issue
appeared and disappeared, so I leave it at that.
Press F11 just to see if that works.
More to come....
