Firefox faceoff - Nightly vs Pale Moon vs Waterfox
Although computers running the 64-bit version of Windows 7 have become more common, there aren’t many Windows-compatible browsers compiled to run on 64-bit processors. (The exception for now has been Internet Explorer 9.) We took a look at three unofficial Firefox variants made for 64-bit processor computers running a 64-bit version of Windows, giving each a series of tests to rate its speed and performance. (One caveat, Firefox Nightly releases a new version almost every day, so your results may vary.)
Google has advanced its 64-bit Chrome browser to beta status
Mozilla has added small ads to the new tab page of Firefox's roughest-edged Nightly build.
