Safari on my Mac, Firefox on the windows machine. Have to say I'd be using Safari there too though, if they had a good working version. I also like efficiency &, while firefox is the best second choice I've found yet, i still prefer safari.
Never tried IE7 though, have to say the earlier versions haven't left me burning to try it.
Have to say I would also uninstall IE from my windows machine if I could. Even with FF set as my default browser, & even when FF is open, the machine still keeps brining up certain links in IE. Damn thing drives me potty.
would class it as an annoying pop-up myself
