i don't know why Firefox has not x64 version for Windows. just Nightly version has x64 version for windows. and it run and starts Firefox faster than Final, Beta and Aurora versions. now x32 Windows is olden and less 50% of users use it. Firefox startup speed is bad. and i has requested than developers team few times than version 4 to make it faster. but not. one time i switched to Chrome, but for some features i came back to Firefox. my PC's CPU is "Core 2 Duo @ 2.40 GHz" but x64 and run Firefox x64 twice faster. please release x64 version of ff for all versions of windows. thanks.

A 64bit Firefox will come, but there are much higher priorities at this time than releasing that. Also, 64bit doesn't help as much as you think it does. If you are having trouble with slow startup, please try the steps at Firefox takes a long time to start up

i didn't lie that nightly 64bit run speed was about 2x of beta run speed.

run speed means opening Firefox at first.

Does Mozilla plans to release 64bit version with Electrolysis (multi-process architecture) with Firefox 36 ? or earlier?

Multi-process Firefox isn't related to 64-bit. Firefox will become 64-bit someday, but there is no roadmap at this time.

Thanks Tyler. Multi-processing also can enhance Firefox speed and performance. i tested. Still is unstable. performance of multi-tab browsing.

Multi-process Firefox is still in testing, but by the time it's released it will be ready. It won't be released until it's ready.

The 64 bit Nightly builds for Windows are only generated to test for compilation errors and do not undergo all the tests that other builds get, so the risk that something goes wrong can be quite high.

There is still a lot work to be done with Electrolysis (e10s)
