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