Some time ago I discovered a site where we can find many different test versions of Mozilla Firefox optimized for Mac
In latko.org are releasing versions of regular Web browser known in its variations Firefox Shiretoko, Namoroka and Minefield , it is best that are the ultimate, fully updated and optimized for users Mac OS X In particular, one of the latest published version is that brings me to write this entry: a version of Firefox 3.7 (first alpha of this version) that runs under 64bit Snow Leopard and recommend that you try. That it bear in mind that this is the very first version that sees the light, which implies much instability, poor compatibility with plugins and existing extensions, etc..
The most impressive aspect of this version is no doubt how quickly it works and how well it manages the resources . In all versions of Firefox I will have proven without a doubt this is the fastest response, hopefully it grows and evolves rapidly since this type of applications that squeeze the most out the system also have an interest renewal and nurturing of new trends and architectures.
