Blazing Fast — 32 Bit (x86) & 64 Bit (x64) Firefox Optimized Distributions

Here are some special builds of Firefox. These are not the official builds and do not display the official branding. They are optimized for particular hardware and OS combination.

What if Firefox was custom built to your particular CPU and even operating system? Wouldn’t it perform faster? The answer to that is a definite yes. The following builds of Firefox are optimized for particular CPUs to run specifically for Windows. They are also optimized according to the real world uses so that it performs the best on your desktop. Please refer to the legend below.

If you have requests for any particular architecture please feel free to contact me.
