I've recently been working on a mambo website, which is a great open source CMS solution. It means that even a klutz like me can throw together a half-useful CMS site in a day or two without having to resort to any coding.
Anyway, the point of my post is that there are some elements of Mambo (and other sites) that don't play nice with Safari, which is my default browser on OS X (there are ways of tweaking Mambo to get it all happy with Safari, btw). For these occasions I had always fallen back to Firefox, but for this project, I have been seriously playing with Camino, and I like it. In fact, I like it enough that Firefox is now gone from my dock, and Camino has replaced it.
I blogged about Camino once before, but never really got round to trying it. I have to say now though that the only thing that Firefox has over Camino (at least, the only thing that actually makes a difference to me) is that Camino does not yet auto-update; you still have to check for updates. With that in mind, Camino 1.0.1 has been released - I recommend you give it a try.
Oh, and it's Mac only ;)
