Firefox x64!!

[Marcus]

Appreciate and thank you for finally building 64bit Firefox at last. Thank you!

I do not have plans to build and upload x64 PGO builds for a while…
I built it to confirm whether the performance of PGO has been improved from VS2013 Update 1.
I think there is scarcely any advantage of Firefox x64 except that Firefox can use 4 GB or more virtual address space…

I think the benefit of 64bit over 32bit Firefox is more than just performance standpoint.

If I recall correctly, 64bit applications have more efficient memory management and more secure (64bit Java, 64bit Flash etc)

32bit is ultimately making way for 64bit, slowly but surely like how 16bit give way to 32bit. 32bit might be "good enough for now" but why limit ourselves when we can explore new frontiers.

That said, this is your build and I will respect your wishes like all other supporters of yours.

Even if it's a one shot, I appreciate your attempt in building a 64bit Firefox for us 😀

Thank you!
