Advantages of the transition to 64-bit include faster speeds on pages using encryption, fast-call type function calls, and more efficient memory mapping of large files. Initial benchmarks from the 64-bit build show impressive gains in certain applications.
A notable downside of the patch for Firefox 3.5 is that it breaks Mozilla's plug-in system, which relies on a 32-bit architecture. However, Mozilla has talked recently of adding official 64-bit support in the near future, so this will likely be addressed shortly.
Firefox 3.6 may get 64-bit support
