Chrome 14 should be stable in about 8-10 weeks. Firefox 8 won't be stable until 14-16 weeks from now. That's around the time Chrome 15 will be out.
This almost-gripe is such a beautiful illustration of how far we've come in upping the pace of browser tech innovation. Thank you Mozilla (for this round).
They forced pretty much everyone in the browser area to play catch up with them to stay relevant, and the results are really awesome (and not just in release cycle speed).
"Oh, you're using IE from August 27, 2001? That's a little bit out of date. Because browsers update so fast, we can only support browsers released within the last 2 years." :-)
The point was that Chrome 13 will become stable in 2-3 weeks from now (an Chrome 14 - beta), and then in another 6 weeks Chrome 14 will become stable. While Firefox 6 will become stable in 3-4 weeks, then another 6 weeks for FF 7, and then another 6 weeks for FF8, before it becomes stable. You do the math.
Fx8 vs Chrome 15 might be very very similar...
