One major site that has not come around to Firefox is Netflix. Cannot "View Instantly", and I STILL come across other sites that are not making it possible to use this browser for their applications. Makes me wonder if Google Chrome is going to be in the same boat? I don't much mind bouncing between browsers, but can't quite put my finger on "why" major webmasters refuse to make their sites compliant across the entire spectrum. Many of us are careful to check our apps on all browsers..... Hmmm.
The only reason I dont like chrome is the lack of add-ons... which is why Im still using firefox (even though ppl claim that chrome is faster - i think all the browsers are pretty much the same, really depends on your internet connection)
As stanley already said chrome lacks addons and thats the main reason I am not willing to shift to chrome
