Post 64-bit Firefox for Windows should be prioritized, not suspended

The Red Panda, or Firefox, is an adorable inhabitant of forests in foothills of the Himalayas.

The stable, supported, mainstream version of Firefox on Windows is a 32-bit application. Even if you use 64-bit Windows, if you use Firefox, you're using a 32-bit browser. The exception is if you're using the Nightly build of Firefox. This represents the latest, cutting-edge version of the browser, and it's available in two versions: a 32-bit one, and a 64-bit one.

However, this won't last much longer. Mozilla announced last weekit was no longer going to produce 64-bit Nightly builds of Firefox for Windows; nor will it run automated tests of 64-bit Firefox. The browser's future on Windows is resolutely 32-bit. Linux and Mac OS X, in contrast, both have official 64-bit versions.

Several reasons were given for this discontinuation: many plugins have no 64-bit version, Mozilla's bug reporting and tracking infrastructure provides no clear distinction between 32-bit and 64-bit problems, bugs go unfixed because the 64-bit Windows version is not deemed a priority, and JavaScript performance in the 64-bit builds is substantially slower than in the 32-bit version. Further, Mozilla developers say they won't fix any bugs that only manifest in 64-bit versions. Firefox developers say a fully supported 64-bit version of Firefox won't be released in the first half of 2013 and it probably won't make the second half either.
