Too heavy mozilla drives mac users to chrome (Score 1)

I've been a fateful mozilla user for years. However on MAC due to the slowness of the browser and the high RAM consumption I permanently switched to Chrome. So may be they should make an experiment on how to keep their MAC users because until now they've been great at that. When I went to buy VPN from http://vpnarea.com I was surprised to find out that they had an extension for Chrome but not for Mozilla.
