Decent browsers for Linux? Anything to replace IE?

[Joseph Jones <joe@bumpycarrot.cjb.net>]

While I'm a huge Firebird fan, IE was better at some tasks (yes, they 
are non-standard HTML tasks, but what can you do when that's what the 
industry uses? *sigh*).

I've tried Konqueror and found it lacking extremely (yes, I love it as a 
file manager when combined with qvwm, but it simply isn't as 
full-featured as other browsers) and Opera seems worse than Firebird. 
So, can anyone suggest a browser that tries to replicate these changes?

Many thanks

Joe.
