Slow loading of many websites
Firefox is my default on 3 Windows 10 PCs. It suddenly has slowed on all websites (they eventually load) I've entered, other browsers not affected. I did a refresh, removed add-ons & did a Firefox safe mode setting. Pages load just as slow; they are super-fast in my 2 other browsers. If this continues, I will have to switch my default.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

This same problem just began on three separate PCs. It only is a problem in Firefox. Edge & Chrome are ultra-fast; Firefox was until two days ago.
