I love the tabs, you don't end up with 2 rows on your task bar. I reckon firefox works better with CSS, I can normally get a site looking right with firefox, no sweat, but then have to break the rules and put in dodgy hacks for IE because it doesn't interpret it right. If sites look funny in firefox it's because the developers are lazy and don't code for the major browsers. On that count... anyone know a safari simulator?

I know from my error logs that Macintosh have a problem with my CSS for the images. Instead of doing it right like firefox and IE, it looks for the file '/images/file.jpg' instead of simply /images/file.jpg, like it forgets to remove the ' from the CSS command... obviously the images are missing I bet... I don't have a Mac to check.

Firefox most definitely - however I do use IE just to double check how the pages of my site look in both browsers.

Im using firefox... there are lots of add ons and tools you can install there.
