I read the first three entries in this post, and had to blog it!

Mozilla Firefox + Adblock Plus + Adblock Filterset.G.Updater + All-In-One Sidebar + Book Burro + CustomizeGoogle + del.icio.us + FireBug + ForecastFox + Gmail Notifier + Greasemonkey + keyconfig + Menu Editor + NextPlease + NoScript + PDF Download + Tab Mix Plus + Web Developer. Damn it, why is Firefox taking 600 MB?

(Emphasis is mine!) :)
