How to stop Microsoft Office pop-up window in Firefox 86.
I installed Firefox 86 and I'm getting Microsoft office pop-up window. I have block pop-ups selected in options. I've uninstalled everything pertaining to Microsoft office and it's still happening. Seems to happen when I hit the page back button on my mouse. I'm running AdBlock Plus. It's driving me crazy. Anybody have any ideas? Thanks much for any help.
