I'm an Opera user at home, but at work I'm stuck with Firefox. There are a couple of add-ons that I use, but most are just to make it perform a little more like Opera, mostly because i'm an efficiency geek.

Searchwords- Lets you attach a keyletter/word to any search engine, so instead of going to yahoo and searching for "cigars", you can just type "y cigars" in the address bar

Speed Dial - Whenever you open a new tab, you get a sort of "Top 9" of your bookmarked sites, so the sites you use most often are only a click away.

Firebug - This one is a must have for web developers. It allows you to dissect the code on pages, and dynamically make temporary changes to html and css to see what the result is.

IE Tabs - This is the only extension I use that isn't already integrated with Opera. It allows you to, at the click of a button, re-draw the page in whatever version of Internet Explorer you have, inside the Firefox tab. This is great for sites that still aren't fully functional in Firefox, or... as above, web developers.
