BehindTheOverlay Chrome Extension Kills Overlay Popups

Remember, someone somewhere had put together a Google Chrome extension to block these annoying overlays that are hard to X out of, for the most part.  For an example of an impossible to X out of page is Mercola.com

THIS one is no longer available.

Overlay Blocker is no longer available in the Chrome store, but they now have one called BehindTheOverlay.  BehindTheOverlay Chrome Extension Kills Overlay Popups.  It works, so far.

You know these annoying javascript things that have to data mine emails in order to sign up for newsletters, even though there's an option on the sidebars to sign up for them.  And also soliciting for Facebook Likes for their facebook pages, etc...

It may need to be tweaked one some social media websites, so just play around with it and perhaps whitelist some sites, if they don't offer full functionality.  At least this should stop alot of that nonsense.
