My Current Set of Firefox Add-ons

1. Adblock Plus – ‘Nuff said.  First add-on I load after a fresh Firefox install.
2. Google Advertising Cookie Opt-Out
3. Autofill Forms – I use this for testing at work.
4. Customize Google – Lets me force strict filtering in SafeSearch for Google searches.
5. DownThemAll – If you ever need to download a bunch of whatever from a page, this is what you need.
6. Firebug – This tool is amazing. still feel like I have a ton to learn about it.
7. Greasemonkey – Love this, especially during NFL and NBA seasons.  Free live fantasy stats, baby.
8. TwitterBar – As if I need another place to tweet.
9. Web Developer – Yes, I know most of this functionality is in Firebug, but I started using Web Developer Toolbar first, so there’s some things I find easier.
10. XMarks – I love having my bookmarks and toolbars sync’d up.

How about you?  Any add-ons you can’t live without?
