Mozilla: Firefox 54 is our "best release ever"

Chrome has been taking advantage of sandboxing and multiple processes for many years now, however that's also been partly the culprit of some of its memory hogging issues.

Mozilla is celebrating this new milestone with Firefox 54 now available for Windows, macOS, Linux and Android.
