I don't agree with the article that Firefox is in trouble, but I'm a Chrome Store dev and I've grown tired of reading people online saying things like "they're just bookmarks", so I apologize if I came across as attacking. I think the advantages that Chrome (and to a lesser extent IE) has will eventually be rolled into the spec, and will be negated, however I don't think Mozilla is doing enough to push their alternative as viable. Their spec, to me, reads as web app best practices and the only original thing they're providing is an install button api.
