Firefox and must have extensions

Quite some time back I moved over to using Firefox. Initially I had some issues (basically related to usage), but now I am Firefox fan. Now, I hardly ever open IE.

Firefox has rich collection of freely available extensions. There an extension for almost everything you could think.

The extensions I use are as follows:
* autocopy
* yahoo companion
* dictionary search
* adblock
* tabbrowser preferences
* mouse gestures
* flashgot
* googlebar
* linkification
* foxylicious
* print preview
* quicknote
* ieview
* targetalert
* greasemonkey
* sessionsaver
* del.icio.us
* spellbound
* webmailcompose
* live http headers
* aardvark
* download manager tweak
* scrapbook
* duplicate tab
* resizeable textarea
* hit-a-hint
* feedview
* super dragandgo

The ones underlined are must haves.

Thanks to all Firefox developers and Extension developers for developing such a fine product.
