Hot on the heels of the slightly delayed official unveiling of Firefox 11 FINAL comes Waterfox 11.0, an optimized build of the Firefox source code for Windows 64-bit users. Waterfox 11.0 contains exactly the same updates as Firefox 11 (see below), plus one major change of its own, a switch from AMD’s Core Math Library (ACML) to the AMD LibM library, which is optimized for 64-bit processors.
Aside from the change to AMD LibM library, Waterfox 11.0 has also been compiled with a new set of flags from the original Firefox 11.0 source code, which should help improve performance further. Other changes, as expected, simply mirror what are already present in Firefox 11.
These include limited support for importing data from Google Chrome, the ability to synchronize add-ons via Firefox Sync, updated support for various HTML5 and CSS standards and redesigned media controls for HTML5 video. Waterfox 11 also includes the two enhancements for developers: a CSS Style Inspector and Tilt (3D) view for HTML pages.
