FireFox 3 on Mac needs force quit almost hourly

[NickFitz]

Safari has always been a bit primitive, poor UI customisation, and V4 is decidedly flakey and slower than 3 (and please, spare me that Top Sites tulipe).

If you just surf the web, then I'm sure it's fine, but if you do any serious web-app development, it's utter pants.

FF offered the best set of tools and plugins for web dev, but the FF devs are clearly not interested in OS X these days, and will not fix the many problems that exist (have existed) since FF 2.0 on OS X.

FF3 for OS X gets worse and worse with every point upgrade.

Firebug used to be good, but seems to be falling apart since Joe Hewitt packed in working on it

I found the WebKit Developer Tools to be absolutely brilliant using a nightly build a few months back - it made Firebug's JS debugger look like a sick joke.
