Ask HN: What are your favorite browser add-ons?

In terms of browsing, these are the add-ons I don't know that I would fair well without:

easyGestures, Adblock Plus, ChromEdit Plus / Smart Bookmarks Bar, Greasemonkey, Foxmarks Bookmarks Synchronizer

Also a fan of some others such as Zotero, Delicious, Tab Catalog and a few others.

My personal favorites in Firefox for personal browsing are: Adblock Plus, Colorful Tabs, NoScript, Nuke Anything, Popup ALT Attribute (for XKCD), and Tree Style Tab.

For web development I find Web Developer and Firebug indispensable.

Inquisitor is the only add-on I use, for Safari. It's a beautiful add-on and it's the only thing that does something for my browser that makes me more productive.

I can't wait till everyone starts using Adblock (Plus) and it completely throws off the Internet economy.

Firebug is a pretty obvious choice. Highly recommended!

I also use Flashblock.. oh and Sage for RSS.
