Waterfox 44.0.3 + PortableApps | 70.3/72.5 Mb
Waterfox is a Firefox-based browser especially designed for 64-bit operating systems. Waterfox uses the same profile that Firefox does. If you uninstall Waterfox make sure you don't have the remove personal data box ticked! Waterfox is basically a 64-Bit version of Firefox. The Firefox source code is taken and compiled to run specifically for 64-Bit Windows computers. To make Waterfox stand out a bit more, its compiled with optimizations so that it will run more efficiently and faster than just compiling Firefox as a 64-Bit program.
