When did Firefox turn into Netscape? What I loved about Firefox was how it was lean and simple to use. If it wasn't for a handful of add-ins I would have switched to Chrome or Safari by now... and it's only a matter of time until those add-ins are available in one of those browsers.

This seems to be a problem with lots of open source projects, features keep getting added and added and added. It's easy to add new features, it's hard to take a stand and keep things simple.
