It's a pop up ad and I have an ad blocker.

Do you get this pop-up on every page, or on some specific pages  ?

Where on the page does this pop-up appear ( e.g. at the bottom of the screen )  ?

Can you attach a screenshot?

• use a compressed image type like PNG or JPG to save the screenshot

Sorry guys, It's not a Firefox ad. I have Yahoo search and the ad is Yahoo's. Thanks for your time. geosdek
