The article said the "dev" channel of Chrome, which is equivalent to Firefox's nightly build, so they are about equal. It just happens that the current nightly channel of Chrome might be released earlier.
It's not the same thing. How is Firefox 7 version called then? What about 6? Does Firefox have 4 modes instead of 3, like Chrome (dev, beta, stable)? Firefox's "dev" mode might be equivalent to "Chromium" mode for Chrome, in which case I suppose Chrome also has 4 modes, but their dev modes are still not equal to each other.
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.
