I also use AdBlock Plus with IE on this machine. The number of ads blocked is quite large; the unpaid version of AdBlock Plus informs me that the daily limit of 200 blocks has been reached and that I should buy the paid version.

A result is that I also get that "not found" message at the bottom where those annoying Google ads were appearing. As some of them have been completely inappropriate to TFB, I would like to see them vanish. In addition, when TFB "hangs" in loading, the bottom bar usually shows that some ad is loading slowly.

I clicked on them occasionally (some I was actually curious about) but mostly because (even though it may have been a small amount) it helped Foggy generate a little revenue to maintain this site.
