Firefox extensions. Which do you use?

JMac, the dictionaries are here: https://addons.mozilla.org/firefox/dictionaries/?lang=en-US

I decided to keep NoScript; my level of paranoia exceeds my level of annoyance with it. There's been too much publicity about the JavaScript vulnerabilities in Firefox, I expect the number of exploits to rise. So my list is now:

AllowClipboard Helper 0.5.5

BBCode 0.4.1.3

Bookmark Backup 0.4.2a3

ChatZilla 0.9.76 [DISABLED]

FlashGot 0.5.97.01

IE View Lite 1.2.5

Make Link 2.0.4

Nightly Tester Tools 1.2

NoScript 1.1.4.5.061030

QuickNote 0.6.0.2

ScrapBook 1.2.0.6

Talkback 2.0

WebmailCompose 0.6.6

I keep ChatZilla disabled when I'm not using it; like I said, I'm paranoid. I've kept the alpha version of Bookmark Backup 0.4.2 because all the release version has different is added localizations, which I don't need.
