Camino is a Gecko–based browser for Mac. It is a little brother (sister?) of FireFox. But unlike FireFox 3 it is works at least two times faster. Why is that? No idea. In addition it takes less memory and does not seem to leak it. Fonts look better in Camino.
I decided to use Camino after FireFox hanged up once again and destroyed all my tabs (despite of session saver extension).
I found only two problems with Camino.
Firsts, it does not import FireFox bookmarks correct. It looks only in the "default" profile ("default.profile" folder). I have FireFox 2 with that profile and FireFox 3 with another profile. Camino does not prompt me what profile to import and gets FireFox 2 bookmarks.
Secondly, it is not possible to install FireFox extensions to Camino. On other hand it can be good: the less extensions, the faster it runs.
1Password is supported for Camino too, so I will not loose any saved login.
I also heard that Opera works fast and well on Mac but I could not get used to it on PC and I do not think anything will change for Mac. So my default browser for now is Camino.
