What version of FF, loads OK for me, I'm on ver 41.0.1. If you have that version then there may be an add on to FF getting in the way
Sorry for the delayed response. I am using 41.0.2. It seems to load now, it is just a lot slower with Firefox than Chrome
Also after I upgraded the program from 15.something to 16.something, I've noticed something weird. My setting is to start protection from start-up, but I always notice variable amount of time after start-up, I get a popup saying protection enabled. Isn't protection supposed to enable right at start? What is going on?
