Some of the drop-off in use is due to Christmas, possibly all of it. The reduced use only started two weeks ago, but is more marked than the previous year. We won't know for sure for another week or two.
We do know. Go to https://addons.mozilla.org/en-US/firefox/addon/firebug/stati... and select a custom range starting 2010-12-01 and ending now.

You can see that the dip then is almost identical to the one now. In fact, it was a bit bigger then!

The author of the post knows zilch about trend analysis - it's only link bait.

The dip this xmas looked bigger to me. shrug
Turns out you're right. There apparently was a bug in the usage stats at Mozilla. See http://blog.mozilla.com/addons/2012/01/04/issue-corrected-wi... .

The underreporting lasted for 2.5 weeks.
