I saw that particular article too yesterday. The author has been writing a series of articles on the decline of Firefox, this one is the latest. It is very sad.
Like plodr I have avoided Chrome per se like the plague, and for the same reasons and more; yet several of the browsers that I use are based on the Google-supported Chromium. And like plodr said perhaps a lot of that Firefox share of the market includes Palemoon, Waterfox, MyPal, Slim, SeaMonkey (all of which I use), and others. Palemoon and MyPal might survive a Firefox collapse but the others would probably disappear.
Just where are things headed?
Bring back the old Presto Opera! (Sigh)
