I can see unofficial binaries are out, but when are Mozilla expecting to launch the official 64-bit version? Working as a web developer my next project will require compatibility with 64-bit browsers as well as 32. In Internet Explorer there are differences, so I expect there also will be in Firefox. Thanks

There are no plans for an official 64 bit Windows version of Firefox yet. Mozilla do have development versions but the only official release of Firefox 4 on Windows will be 32 bit. There will be 64 bit versions of Firefox 4 for Linux and Mac. The 64 bit version for Windows will be after the release of Firefox 4.

I, for one, have returned to Internet Explorer, and have removed Firefox from my programs.
