64-bit Firefox is the New Default on 64-bit Windows (mozilla.org)

Posted by msmash on from the moving-forward dept.

An anonymous reader shares a blog post: Users on 64-bit Windows who download Firefox will now get our 64-bit version by default. That means they'll install a more secure version of Firefox, one that also crashes a whole lot less. How much less? In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more.

    All my windows machines have 64-bit Windows installed, but I have already installed the 32-bit version of Firefox on them (because that was the default at the time). How about automatically UPGRADING my 32-bit Firefox to 64-bit on machines that can handle it?

    This is scheduled for the next release, Firefox 56.

    Also when people had 4GB RAM max on their computers there was no advantage of a 64bit OS. The 64-bit applications are larger and they are not faster. If the 32-bit version of Firefox crashes more then it's because they aren't spending as much time maintaining it.

    64-bit applications can be faster if the code benefits from the twice available registers.
