Hmmmmmmmmm
Are they both freewaRe and what engine do they use (Firefox or IE)?
Lol, not every browser is based on FF or IE you know! Opera runs it's own engine, Presto. Flock is Mozilla-based but tweaked for Twitter usage and the like.
Strange original post I have to say. Two almost unconnected browsers and no mention of FF, Chrome/Chromium, Seamonkey, Epiphany, K-Meleon, Safari etc etc.
Hmmmmmmmmmmmm
Aren't all browsers free?
No not all. Ironically, the most popular of them all, IE, requires a valid Windows license!
