[Tracking meta bug] officially support Windows 64-bit builds in Thunderbird
Firefox is working towards supporting (and making official) 64-bit builds on Windows. We should be doing the same on Thunderbird. Currently though, this isn't high priority and will unlikely be included in a Gecko 2.0 based release as the gecko platform won't be officially supporting 64-bit builds, hence we won't be either. We will slowly start to ramp up 64-bit windows support on Thunderbird ready for some future release, however the time scales are as yet undetermined and this will depend on Firefox support of the 64-bit builds, so please be patient. This bug will be used to track the work necessary for Thunderbird. Core issues are tracked by bug 471090.
Are you serious ?! Your statements do not lend much comfort to the future development of Thunderbird. I have been running win64 version of Firefox full time for over a year. Firefox HAS delivered for a very long time in the nightly trunk. The third party Win64 build of Thunderbird was a pain, but it runs and the OFFICIAL win64 Thunderbird nightly (comm-central) runs nicely as well. Firefox HAS delivered to the point that all extensions need to pony up or die. The fact that your public has been asking for this for two years is reason enough to develop a solution. It matters little whether there is significant technical reason - it is what is being asked for and you will soon find greatly diminished support for 32 bit apps on windows. Perhaps 64 might solve some of the slowness from operating ludicrously large imap accounts. Anyway - I think that having Lightning is a critical feature for many organizations and would be the tipping factor to push wide spread adoption. In the mean time, I guess I just have to be envious of 64bit Outlook 2007 (along with Word and Excel - all 64 bit version as verified by task manager and file properties) that came PREINSTALLED on my daughter's bleeping netbook in 2011. Just my .02 cents. Signed, Patiently Waiting.
Duane, whilst 64 bit is perceived to be better, we know from testing that Firefox 64 bit is not currently as fast as the 32 bit version. The work required to get 64 bit ready for release is significant and has been decided it is not the highest priority. You can read more about the decision here: http://groups.google.com/group/mozilla.dev.planning/browse_thread/thread/1cc83f09e7f5efe3/ec7afa6636637c71?lnk=gst&q=windows+64#ec7afa6636637c71 Thunderbird has already made the decision not to support 64 bit officially until Firefox does, as a significant part of the code base comes from Firefox, and would put us at risk of issues if it was not supported by Firefox. If you have any queries about these decisions, please use the relevant planning lists and not bugzilla - bugzilla is for bug tracking and fixing things, not for policy decisions. As I realise this hasn't been mentioned before, for those tracking this bug, nightly 64 bit builds of Thunderbird are available from: http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/latest-comm-central/ These should be considered experimental and whilst we will try to keep these going, it is not our highest priority, so they may break for a period of time if we encounter 64 bit specific issues.

Summary: [Tracking bug] officially support Windows 64-bit builds in Thunderbird → [Tracking meta bug] officially support Windows 64-bit builds in Thunderbird
Note, Firefox has bumped their minimum requirements to win7/64, per bug 1094013 and bug 1093741
Added CC from bug 1226149.
Hi guys. Well, Firefox has an official x64 out since v43.0 or 42.0 I think. Will we see an x64 official from Thunderbird soon? The 3:rd party ones are old, not any good. I want the official build.
We would like to support 64 bit Thunderbird, but somebody has to be motivated to put in the work. This is complicated because it requires support from the Mozilla build team, but they are not tasked to do anything new for Thunderbird, only maintain the old.
I would very much welcome 64-bit Thunderbird to be supported. It's time!
If you cannot support both branches then retire 32bit, the problem is the argument that 64bit requires excessive effort does not hold water whilst you do support 64bit linux. I see there is 64bit nightly builds, surely all one has to do is apply the nightly build script also to stable and job done? At the very least do it for beta builds.
This probably wouldn't be hard to finish off for version 52 ... not so certain about the mapi piece.
Any idea when this will appear on http://ftp.mozilla.org/pub/thunderbird/releases/?

Is there a place to start testing 64 bit "beta" builds of Thunderbird? Surely, this has got to be wrapping up soon. Are there tracking bugs for starting to ship this to small groups, the same way it was done for Firefox?
