My Firefox just sits with one or two tabs open with the little dot rolling back and forth doing nothing for 4-5 minutes. While I'm getting emails and using EDGE right now!

Chosen solution

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

See "Visual Studio 2015, 2017 and 2019":

You may not need the latter (32-bit version) if you use 64-bit Firefox. You may have to reboot the computer.
