I couldn't make heads or tails out of it when I last had it installed. I could give it another try. Over the years, I've pretty much tried them all........... IE being one of my least favorites! I'm not sure what I would gain over Waterfox. I'm not much on ads, and adblock plus works well. IE had some kind of blocker, but the instructions for porting it to Edge were wrong, so I got ads. They both crash anyway, so no biggie.
I remember one of the things I didn't like was it wanted me to log in to Windows with my gmail addy. Seemed a bit intrusive to me.
Well I installed it and got adblock plus back!!!! I made it default and we'll see how it goes.
Did I mention that I also play bass? Altho I can dance a bit...with my lady.
