This is awesome news. The single biggest reason that I initially moved to Chrome, from Firefox, was the memory consumption situation. But lately, Firefox has gotten a lot better, and I've basically switched back to FF now as my primary browser. Hopefully this will make the situation even better.
And that's good for everybody. Competition is a Good Thing and it would be a shame if Chrome become so dominant as to completely displace Firefox. A healthy ecosystem with a great Firefox and a great Chrome, along with IE, Opera, Safari, etc., should benefit everyone in the long run.
Chrome and Firefox been using memory at equal proportion. I use exactly two add-ons and comparing FF/Chrome to IE to check on memory consumption, I see IE doing much better.
