A few more:

Bookmark Duplicate Detector: Detects Duplicate Bookmarks when bookmarks are added and specify where is the previous URL.* You can also search and delete duplicates URL already in your Bookmarks.
* Not sure about that first bit in Firefox 3.

Statusbar Clock: Display the date and time in your browser's status bar. Or just the date, or just the time, or maybe a cheerful message to brighten someone's day. It's quite customizable.
Firefox: 2.0 – 2.0.0.* [works fine in Firefox 3 if you overide version checking]

TagSifter: Firefox 3 lets you tag your bookmarks, but it doesn't give you a great way to browse your bookmarks by their tags. TagSifter tries to.
Firefox: 3.0 – 3.0.*

Update Bookmark: Allows bookmark properties to be set to the current page's properties or to clipboard text quickly via the context menu.
Firefox: 3.0b1 – 3.1a1pre

I was about to mention Foxmarks since Google browser syc is not compatible with FireFox 3.

The only issue is that is takes a couple of seconds to sync on opening the browser before you can use it. Unless that's something I've done wrong??

I love add-ons. :) Here are a couple that I find useful.

FaviconizeTab I always seem to have too many tabs open and this reduces their size down to the size of their icon.

Tab X When the tabs are reduced in size this add on makes the close button visible.

Objection is another good one, it allows you to clear out flash cookies (also known as LSO's) which normal cookie deleting won't clear.

Googlepreview brings a nice touch to your Google search engine as it displays a thumbnail of the page next to each search result and i find no speed impact.

Gspace is one of my favourites. Allows you to use (multiple) GMail accounts as online backup space. It'll even allow you to upload files >10MB.
