Just downloaded Quantum and Ill tell ya, It's a hell of a lot better than the old version. Pages load faster and RAM usage is basically cut in half.

I've taken this and all other positive comments on board.

I can't wait to Install and test It, both security-wise and from an average end user's standpoint.

Its really fast and somehow powerful, If you checked it, take a look at the developer version too its amazing.

One question though, I've still got the old Firefox and will this affect the newer version?

I'm not sure but I have installed both stable and beta version, Something changed in both Hahahah.
So it is better to install just one of them.
