My favorite Firefox extension these days is Foxmarks Bookmark Synchronizer. I love being able to store bookmarks on my computer at work and have them show up on the computer at home and vice versa.
I was excited with the prospect of del.icio.us when I first heard about it, but quit using it because it just felt cumbersome to me. Plus, to get to the bookmarks I had to navigate to their website and then sort through my list.
I like having the bookmarks attached to the browser a little more.
The downside, of course, is when I am stuck on a computer with only IE installed. I feel quite a bit lost then. Anymore, I rarely find myself in that position, though.
