10 best firefox extensions of 2009

There's a pretty good chance that Chrome will become my primary browser in 2010. But I will always have love for Firefox. Here are some of the reasons why: 

1. Lastpass - Save all your passwords across computers/browsers.
   
2. X-Marks - Save all your bookmarks across computers/browsers.
3. SkipScreen - Makes sites like Megaupload & Rapidshare bearable.
   
4. Woot! Watcher - Know what's currently being sold at Woot.com.
   
5. Adblock Plus - Block ads!
   
6. DownThemAll! - Download multiple files with one click.
7. TabMixPlus - Firefox tends to adopt many of their innovations in each new release. 
8. Greasemonkey - allows you to tweak almost any webpage. 
9. Download Statusbar - Replaces the clunky FF download manager. 
10. Foxytunes - Play your music within FF.
