I have both of them to try.
I don't care for either. Under the hood isn't bad. They run fine.
What bothers me is they both bear a striking resemblance to Google Chrome.
If IE, FF and Chrome keep going on the road they are on, we poor computer users won't be able to tell them apart.
JHFC, If I wanted to have a browser that looked like Chrome, I'd be using Chrome.
I sent off nasty-grams to both The Evil Empire and Mozilla. I doubt it will do any good.
That is all.
