If you ever want a demonstration of how flawless Mozilla's update system is, use Minefield for a while. Every single day the browser updates itself to the latest nightly build - not had a single crap-out yet and the whole update process takes around 20 seconds.

Compare that to Microsoft!

Oh, and has been said above, I would much rather have a browser be updated every week (or even every day) with the latest flaws patched, than one updated whenever the dev team (and end user, let's not forget*) can be arsed, leaving flaws exposed for much longer. The article should be praising Mozilla for getting patches out so quickly. Nicely done, lads and lasses.

*I say this bit because a lot of the XP users I know turn off Automatic Updates straight away. No-one really trusts MS to manage their PC, especially after they labeled "Genuine Advantage" anti-piracy software as a critical update.
