I love Camino but there's one FF extension that's simply amazing, Foxmarks. I know I can work without it, but it makes life so much easier to have all of my bookmarks automatically synced online to different machines using FF.
I use Safari, Camino and Firefox daily. But Safari is the best browser BY FAR. Firefox is so ill-equipped that it has only very limited uses. The history, cookie and cache capacity is so tiny it is virtually unusable in most cases.
