You can use full Firefox downloads to install Firefox on systems without Internet connection, or for distribution purposes if you want to install it on multiple systems. While users want the latest version usually, older versions may sometimes be required, for instance when the latest version causes issues on a system.

In other words, users will get the latest version of Firefox when they run the installer and they may re-use it. Unlike the offline installer, which always installs the version of Firefox that you downloaded, stub installers query Mozilla during installation so that the latest version of Firefox is downloaded and installed.

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.
