For the last few hours I been seeing way off topic ads, but so far only when using Firefox - very strange
So far I've added a couple hundred URLs to the Block URL utility, but they aren't being blocked, even after waiting a couple hours.
Most of the OT ads are EDUs teaching a variety of topics, all unrelated to my content. Something similar happened a few weeks ago where Wall Street & Investment Bankers seemed to take over all the ads for a few hours.
Anyone else seeing this?
