Granted it’ll be a while until it arrives on my desktop, but the Firefox team has began adding Aqua elements into their web browser. Checkboxes, drop down menus and buttons are on their way. Users probably won’t see them until next year, however it is something to look forward to and something that I’ve been waiting a long time for.
For the latest and greatest information on Firefox Mac design, check out the Boom Swagger Boom blog. They even have information about Firefox for Intel Macs. 
Also, if you haven’t been to GrApple lately they have some great new themes. I’m running GrApple (Zaphod) and it’s very very nice! Highly recommend it.
