A friend just pointed out something that should have been blindingly obvious: Firefox is slow, and if you use the same engine with native Mac libraries, things are much faster. So if you use a Macbook, download Camino.
There are a couple things I miss, here and there, but overall it’s great. I miss the spellcheck squiggle that’s in Firefox 2.0, as well as – to move between tabs, and also the support for multiple homepages.
The funny part, of course, is that I’m complaining about slow Firefox is when there are worse browsers out there.
