this is mac osx native firefox, much like camino. but with extensions, lol Thanks Josh Aas and other ppl's hard work UPDATE: The mod locked my other post, coz he thinks that post states the same info as this one. So i think I need to explain here, in this old post, Josh (developer of Camino) began to test the cocoa firefox, the build was experimental, test builds were not in the official mozilla trunk nightly build directory. And Mozilla developer just landed the cocoa widget on the OFFICIAL TRUNK BUILD TODAY, 2006/09/28 from tomorrow on, anybody who use official firefox Trunk (minefield) will have cocoa widget! Congrats!
