Gone were the days of having to navigate the world of DOS and its strings of seemingly indecipherable commands. More than two decades later, Windows 10 continues to make computing easy for people in the 2020s and beyond. The UI made installing programs and games extremely easy. 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.Ever since Microsoft released Windows 95, the company has made personal computing easy for billions of people around the world. You can still manually install 64-bit Firefox, if you choose.

Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number: If you’re running 64-bit Windows ( here’s how to check), your Firefox may already be 64-bit. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit. Also, with the jump from 32 to 64 bits, a security feature called Address Space Layout Randomization (ASLR) works better to protect you from attackers. 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.
