I have loved the Firefox addon for years, but today, I started seeing ads everywhere. I investigate, and come to find they're allowing 'unobtrusive' ads. Except it seems that unobtrusive to them means all ads! GRR! Looked at some forum threads and followed suggestions, like installing the older version of the add on, but nothing worked. Someone suggested Ghostery, which I just installed, so we'll see how that works.
