Much as I've liked Firefox on Windoze, I'm not liking it much on OS/X (Tiger). It seems to do this weird thing where it uses the Safari download manager, and then it gets confused and won't open any more windows!
Also, it seems to be a real memory hog... I'm getting 360 Meg virtual memory size - !
And I don't like Safari -- it doesn't show you the URLs of links when you put the mouse over them, and the way it colors the URL entry box to show loading progress just doesn't work for me...
So I had a look around. Camino looked good, and I found another one called Shiira. Since I have a minimac with a paltry 256M of RAM, I ran a simple test where I loaded two tabs, one with the AC home page and one with my work webmail. Results:
Firefox: Real memory 39M, Virtual 304M
Camino: Real memory 31M, Virtual 299M
Safari: Real memory 23M, Virtual 125M
Shiira: Real memory 18M, Virtual 130M
Out of these four, I like Shiira best so far. I'll use it for a while and update. (So it doesn't have extensions, but I've never used them anyway...)
