>I like the look of firefox (I'm using the tabs feature at the moment).

Excellent program. Been using it for months.

Tabs: if you regularly open a set of pages (sites), save them as favourites in their own separate folder (not too many files).
Place the folder in the "Bookmarks Toolbar Folder". Whenever you want to open them as tabs, click on the folder with the mouse wheel and all the sites open simultaneously. Cool!

To close a tab click on it with the wheel.
