System requirement for Firefox 10 shows double standards between Mac and Windows platforms. Firefox 10 only support Intel-base Macs with Mac OS X 10.5 (Leopard) being the oldest operating system supported. While in Windows platform, almost 12-year-old technology Windows 2000 is still being supported.
Let's not forget, it was after the release of Firefox 4 last March that Mozilla decided to rush out the Firefox major version release cycle to 6-week, making each major increment not as meaningful as the number used to be.
