Anyway, if you have a 64-bit operating system and are open to the idea of using a 64-bit browser than Waterfox is for you. You can download it here alongside its prerequisites.
Waterfox is a high performance browser based on the Mozilla Firefox source code. Made specifically for 64-Bit systems, Waterfox has one thing in mind: speed.
Why should I use a 64-Bit version of Firefox?
For some people with older systems, the 64-Bit version loads quicker and is much more responsive than the 32-Bit build. For people with newer systems, it allows them to use the full potential of their systems.
If there are any bugs, where should I report them?
Unfortunately, since this is a 3rd party build you cannot report any bugs and you’ll just have to hope that they get fixed in the next update by Mozilla.
Is my experience limited if I use a 64-Bit version of Firefox?
The major plugins such as Adobe Flash, Sun Java, Microsoft Silverlight all have supported 64-Bit binaries available.
How does it compare to 32-Bit Firefox?
In benchmarks, the 64-Bit variant of Firefox out-performs the 32-Bit variant. Also because this variant is being built specifically for Windows, there might be further performance increases.
Were there any optimisations made?
Yes, Waterfox was compiled with SSE, SSE2, x64 favoring and the following optimisation flags: /Og /Oi /Ot /Oy /Ob2 /Gs /GF /Gy
Do all my Add-Ons work?
Yes! Add-Ons work on any version of Firefox, on any platform.
I get a msvcr100.dll is missing error.
You must have the Visual C++ Redistributable file linked in the download page installed.
How do I fix the blurry font?
Type about:config in the address bar. In the filter at the top type gfx.direct2d.disabled. Change it from false to true.
