strange pop up only happening on FOFC

Not an add but something from Windows.

Running Fifefox it says

from AdMeld (http://tag.admeld.com)

What should firefox do?

Open with
Save file


I have been cancelling but it pops up everytime and so far only on FOFC. Any thoughts what it may be?

Sounds like something from the ad-loader that has a bad/non-standard javascript tag.

Are you using any ad-blocker software?

Strange pop up? You're swinging under the ball too far, you need to try to get on top of it more.
