Shiiii... really? How much content can you view at once? The most I've ever had is around 10. Opera is kinda nice as a lightweight and simple browser, but really it's just empty and featureless. Some people see Firefox as being bloated, but they're options people want and of course many are optional themselves. If you spend a lot of time surfing the web it's nice to have everything you want around you, making life easier, simpler and faster.
^ I tried out Opera for the first time and one thing it is not, is simple. I love options but here's what Opera lets me choose: I can have a View bar, a start bar, a main bar, a navigation bar, a personal bar, etc etc. I mean for God's sake! And then there is the amount of options I can choose in the preference menu. It's like they had a meeting and every person's opinion was added in without much thought. I don't know, it just doesn't feel right for some reason imo. Even the scrolling is weird. I love how Firefox and Safari have the same smooth scrolling like butter on the Mac. It's really tacky on Opera though. I'm sure there's a smooth scrolling option in there somewhere but I'm too lazy to dig it up behind those other preferences on top of more preferences. I'll stick with Firefox.
Firefox. It's grown a little chunky over the years but it's still the most extensible browser around and still plenty fast.
Firefox is the only one that has descent add-ons. Tor Firesheep (heh) Firebug HTTPS everywhere Flashblock NoScript There are just too many things that don't exist on chrome. And the complete lack of control over where I place my buttons, bookmarks, and tabs frustrates me.
