Googlebar: Cos it gives you easy links to all those special searches like google scholar (which searches .edu sites), and groups (which searches text usenet archives)
IE tab: for those annoying and badly programmed sites that refuse to believe Microsoft doesn’t actually own the web…
Plain text to link: Because I’m lazy and can’t be arsed with copy and open new window, then paste into the URL bar…
Oh, and FireFTP: Because it does some useful recursives that filezilla and winSCP don’t do so easily amongst other things (and saves logging in to the console and bashing commands at your web space).
