Why? There is no need to commit resources to develop 64bit Firefox on Windows at this time. Please cite a need for it and I will pass it to the dev team. We are slowly working towards it, but there are much more important things to do that actually have an impact on Firefox's experience, unlike 64bit which is just something that is a nice to have but doesn't make Firefox run any smoother.

Snarky replies by "developers helpers" are totally uncalled for.

I agree with JaineyCakes. We install Firefox on all our clients' machines. We're not used to getting smart aleck answers from our vendors. (Or at least not the vendors we keep).

You asked for a reason why you should developing a 64 bit version for Windows. Well here are our reasons: - We have multiple machines with 12 GB or more of RAM - We and our clients have been running 64 bit Windows since 2009 (at least 5 years). - Almost all our other applications that we depend on in our business are 64 bit (and have been for years). - Increasingly, our clients are running more applications concurrently, including more and more tabbed sessions within Firefox. Also the complexity of the apps they run within the browser continue to grow in complexity. - Our clients' tolerance for slow performance continues to go down every year.

Not sure if any of this matters to Mozilla. But we used to consider Mozilla to be a technology leader. Not sure if you still do.

All the arguments that you gave are good reasons for your Operating System to support 64bits, but not the browser. Every Benchmark and real world test shows that 64bit Firefox is not significantly different than 32bit Firefox, and while it does allow Firefox to use more memory, there are few cases where that much RAM is needed for a browser.

As I've said, this will happen someday, but there are more urgent priorities that we need to address first.
