Mozilla is being stripped apart and will eventually be discontinued. In it's stead will be a pure browser project and a pure mail/news reader project.
Firebird (formerly Phoenix) is the a Gecko based browser replacement. It's lean, fast and every bit as powerful as Mozilla, which I consider to have the most standards compliant and stablist rendering engine. Opera, IE, and the Amiga browsers pale in comparison. I know because I've used all of them extensively.
Firebird, like Mozilla, has the most advanced collection of privacy and security features ever introduced. I cringe every time I'm forced to use IE with all the pop-ups and stealth cookies.
Firebird (and Mozilla) also supports add-ons like Optimoz, which gives Mouse gesture abilities to the browser. There's at least 2 or 3 dozon other add-ons you can use also.
Granted, Firebird is still in beta, but every nightly build shows improvements on speed and features.
Finally, the best thing about Mozilla and Firebird are that they are both opensource and free. Amiga wouldn't need to pay a dime to port the browser to our new platform.
The Web was ment to be free as in beer and speech, and so should web browsers.
