Firefox 4, 5, 6 and 7 to be released before the end of 2011
Sounds like the main story is that they're redefining what a major version number means a la Chrome.Chrome's numbers are not in the same scale as FF and IE too, of course. Users can't tell the difference between Chrome 6 and 7 like one can distinguish FF 2 and 3, or IE 6 and 7. I wonder, though, if Google was just trying to catch IE in version number with Chrome and once it's at 10, they'll stop increasing it so rapidly.
