You can get camitools and a bunch of other cool extensions from pimpmycamino.com CamiTools isnt going to be updated anymore though. The developer gave up on it because it was taking too much of its time. They're looking for someone to take over.
Camino was my first browser but I switched over to Shiira. Couple reasons, Camino COMPLETELY screws up videos that use WMV plug-in for me. Also there is no option to load new windows in tabs without pressing command in Camino, that sucks, I like my windows in tabs. Just crossing my fingers for Shiira 2.0 now. Uglier than Camino but worth having proper videos and tabs.
EDIT: CamiTools work with the recent stable release of Camino, 1.0.2 I believe.
