Yes, I got rid of Firefox and am using IE and it sucks beyond believe.
* Every time I open it and every other webpage I open, a pop will come up asking me to manage Add-Ons. I once clicked on and managed my addons hoping it would go away forever but noooooo, 2 websites later it's back and it keeps coming back. For the love of God - Stop already.
* A pop up telling me every time you blocked a pop up kind of ruins the point of having a pop up blocker.
* Stop asking me if I want IE to remember a password, if it's not going to actually remember it.
* Certain ad/script heavy sites can not be opened without IE crashing like WSJ, Forbes, Wash. Times, Huff Post (No big loss)
Try Palemoon. It's Mozilla based like Firefox but doesn't fire its CEO's.
No affiliation to FF, apparently.
