There's supposedly an option to allow "non-intrusive advertising" under filter preferences, but I sure can't find it.
What's even more interesting (if not demonstrating the developer's chutzpah), especially in light of the article cited, is the following request:
"The developer of this add-on asks that you help support its continued development by making a small contribution. Suggested contribution: $5.00"
Good golly, Miss Molly!
I guess I mis-remembered the exact nature of the option...got it backwards, but if you haven't "allowed", I suppose that's why you don't see ads.
I wouldn't call it chutzpah, though, because the ads are user option, and with or without them, the add-on still serves a useful purpose.
(Actually, taking money from people to allow their ads to be opted out of is pretty good business.)
