Firefox 64 bit is back! One news clip: http://thenextweb.com/apps/2012/12/...ws-will-keep-nightly-builds-coming-after-all/ You can download the base install here: http://www.firefox64bit.com/ and of course get the nightly version. Once installed, go to help, about nightly, and let it update. Not sure about the memory leak though, but it is very beta. With my amount of ram I don't care though, and it's screaming fast.
