nobody has mentioned linux. I don't think MyIE supports linux. so only firebird and opera are left. firebird is too light on features and can't be compared to the full version of Opera(Search Google)!!
and wizard,try help (I dont remember exactly where it was since i've not installed opera now)
or try clicking the right mouse button and simultaneously move the mouse up and down. A windows pops up saying you have used mouse gestures for the first time and then guides you to the help page.
