What’s the difference between 32-bit and 64-bit?
Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications. 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. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit.
How do you get 64-bit Firefox?
If you’re running 64-bit Windows (here’s how to check), your Firefox may already be 64-bit. Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number: Stronghold for mac os x.

- If you see “(32-bit)” and you are running Firefox 56.0 or older, updating to the latest Firefox version should automatically upgrade you to 64-bit.
- If you see “(32-bit)” and are running Firefox 56.0.1 or newer, then your computer may not meet the minimum memory requirement for 64-bit (3 GB RAM or more). You can still manually install 64-bit Firefox, if you choose.
