Mozilla releases 64 bit nightly builds of every version . Why doesn't it release official 64 bit build of the same version when it reaches stable state ?

    I guess you will have to ask Mozilla. – Dennis Dec 21 '11 at 14:24

    What benefit will there be? What costs would there be? Surely the problems far outweigh the benefits? I've been using 64-bit windows since 2005, but even I can't yet seen the need. The nightly builds are simply keeping x64 on the back-burner for when they might be needed in future. – CJM Dec 21 '11 at 15:12

The main reason for a long time: there were no 64 bit Flash and Java plugins.

    This is the same reason both 32-bit and 64-bit versions of Internet Explorer are installed on a 64-bit Windows system, and that the 64-bit version cannot be set as default. – bwDraco Dec 21 '11 at 14:40
  • Also the reason why it's better to use 32 bit Office, rather than 64 bit Office. – surfasb Dec 21 '11 at 15:56
