Well I have some more Firefox extentions or add-ons that are pretty cool and i like using.

The first is Xmarks and works pretty good to backup bookmarks and sync them easily.

The second is AnyColor and it changes the color of your browser to whichever color you like.

The Third is FoxTab and it does the Tabs in moving way like vista does with the tabs very neat and makes finding tabs easier.

The Fourth is Ghostery it automatically tells you what is tracking you on a site.
