I thought Firefox 21 is a 64-bit browser

Feb 26, 2013. I was using Firefox nightly channel (version 21 till yesterday) because I read here that Gecko 21 will be 64 bit. After the last update, Nightly became Aurora and when I downloaded and started the Aurora installer I realize it is a 32bit browser (because it was going to be installed in Program Files(x86) ) !!!! What channel features the 64bit Firefox?

Win-64 builds are available on the Nightly latest-trunk FTP page.
Scroll all the way to the bottom for the latest builds.

I don't know where you read that about Gecko 21 being 64-bit, because there was an announce back in November that further development on Win-64 builds was being suspended until further notice.

Well, I've been on the Nightly channel even before November 2012, when the announcement was made. And this is is the name of the zip file I installed:


Therefore, you see, I expected when it moved to the Aurora channel, to still be 64bit, but as I said, the installer made clear the Aurora release is not a continuation of the nightly track I was on.

I downloaded the latest zip from your link, but I wish, as a gesture of thanks for the feedback data that has been streaming from me to Mozilla while using Nightly versions, that I would get a full and detailed explanation of what are my options, when they move releases from channel to channel. The way it was handled, I feel, is they used me and they throw me.

There is no known future version of Firefox that will have a Win64 build for release.

The Win64 test builds are only on the unstable Nightly development channel and have yet to be also on Aurora, Beta or Release channel. Every time a new Release comes the versions moves/merges to next channel and Nightly gets a new version.

These Nightly builds are meant more for testers and devs as they get checkins pretty much everyday and therefore a update each day as a result. Also the Win64 Nightlies are supported even less now as they have since been downgraded to Tier-3 platform more recently while the officially supported Win32, Mac OSX 32/64-bit and Linux 2/64-bit builds are Tier-1 platform. The Win64 nightlies are still more for the purpose of catching regressions/breakages as it is possible to break Win64 builds without affecting any of the officially supported builds.
