FaceBlock!
Recently, FaceBook introduced ads into their desktop "wall" stream.
In doing so started a game of Ping-Pong with the fine folks at AdBlockPlus.
Long story short there is no way, using current CSS selection criteria, to differentiate an ad from a news feed item, short of writing your own extension...
Which I did.
You're welcome
For Developers and the Inquisitive
Please Be aware...
I wrote this extension expecting it will have a limited lifetime, and as such I will add to it so long as FB keeps pissing me off.
But aside from that, please don't expect much more development or support for this extension as it was born
out of my hatred for intrusive ads. I expect the folks at AdBlockPlus to have a workaround at any given
moment, but... until then...
