In my opinion, this web browser is just about the best thing since sliced bread.
It is free to download and use, with NO ads etc. etc. whatsoever.
It has built-in pop-up blockers etc. etc. etc. all that good stuff.
But the best part is the way that it allows you to surf the web. Under a single over-arching web window, you can open up as many individual "tabs" which each contain their own web page window. Flipping between open web pages is as easy as clicking the tab.
This program is unbelievably slick.
It also shows your available RAM, IP address, how many tabs open etc. etc.
I'll never use plain-jane windows internet explorer ever again.
