64-bit Firefox will be installed by default on 64-bit Windows

Mozilla has finally made the 64-bit version of the browser default for users running 64-bit version of Windows. According to the company, the 64-bit Firefox crashes 39% less on PCs with 4GB + RAM.

If you are using the 32-bit Firefox on a 64-bit machine, you can upgrade in two ways:

  1. manually download Firefox and reinstall it,
  2. 2. Wait until the company migrate the 64-bit Windows users to a 64-bit version of Firefox.

Mozilla is introducing the default 64-bit browser for Windows long after users on Linux and Mac. Using the 64-bit version should lead to a better performance and security.

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.
