* NoScript (really makes browsing more secure)
* Twitterfox (a pretty nice FF twitter client)
* All-in-One Gestures (Mouse gestures a la opera)
* Web Developer (EXTREMELY useful for web developing. Allows you to easily disable js, css, cookies, images; resize your browser to 800x600 or 1024x768; Outline various types of elements; view generated source (so including anything JS changed; and many other great features, which are sometimes useful in browsing as well as developing)
* Webmail Notifier (I have 3 gmail accounts I have to check, and this alerts me when any of them have new email, checking every n minutes. Also allows me to easily switch which I'm logged into)
* Yubnub as my default search engine for the search box (go to http://yubnub.org/ it easily allows you to use many different sources with simple commands [like "yt rick roll" to search youtube for a rick roll video])
* Adblock with the Filterset.G Updater (blocks a huge % of ads! When I use other computers, I realize that sites that I never knew had any ads on them do.)
WebDev using Firefox. Firebug is just too useful to not use.
I've only ever installed 2 plugins for Safari:
http://www.inquisitorx.com/safari/index_en.php - Search as you type
http://hetima.com/safari/stand-e.html - Enable all types of options in Safari * Adblock Plus
* BugMeNot
* Download Statusbar
* Firebug
* Foxmarks Bookmark Synchronizer
* Full Screen Homestar Runner
* Gmail Notifier
* NoScript
* TabMixPlus
* Web Developer
* Compact Menu 2 (on non-Mac computers)
Also, several keyword search type bookmarks, so I can get rid of the search bar and use the location bar for everything. * g <foo> - google search
* w <foo> - wikipedia search
* y - quick shortcut to news.yc
* cpp <foo> - google search that begins with "C++"
* etc.web dev: firefox with firebug, live HTTP headers, web developer, tamper data

Sample size is only 177, and it is only people that cared enough to read into one particular comment and then look further, so it may not be representative.I used to use greasemonkey for some gmail tweaks, but the gmail labs thing added most of them, so don't need that anymore.
at home-powerbook: safari, firefox to test/debug javascript stuff
PS: Our stats on Google Analytics show that 62% of visitors from US do use FireFox. It's quite surprising to me.
i like safari's developer's tools better than firebug
