If you need to run 32-bit Firefox or manually install 64-bit Firefox, you can simply download and re-run the Windows (32-bit or 64-bit) Firefox installer from the Firefox platforms and languages download page.That is a problem with the ''Montserrat Thin'' font that the website specifies. You can still manually install 64-bit Firefox, if you choose.

Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications. What’s the difference between 32-bit and 64-bit? How much less? In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more. That means you get a more secure version of Firefox, one that also crashes a whole lot less. Users on 64-bit Windows who download Firefox can get our 64-bit version by default.
