Chrome extension provides easy button to close overlay pop-ups
BehindTheOverlay provides a consistent button and keyboard shortcut to close those annoying website overlays.
There are enough distractions on the Web before we even get to the overlays that some sites hit you with, asking you to register, take a survey, sign up for a newsletter, or some-such. And while most overlays put the close button in the upper-right corner, some diabolical Webmasters have become masterful at disguising the X button that lets you close the overlay and enter the site.
If you use Chrome, the BehindTheOverlay extension can help you in your battle against overlay pop-ups. The extension simply installs a button to the right of Chrome's URL bar that you can click to close an overlay that you encounter. BehindTheOverlay just works; it does not require you to sign up for an account or restart Chrome.
And if you head to Tools > Extensions in Chrome and scroll down to the bottom of your list of extensions, you'll see a Keyboard Shortcuts link. Click it and you'll be able to assign a keyboard shortcut to BehindTheOverlay you can use to kill overlays.
If you'd like to test it out, the developer has a far-from-exhaustive list on GitHub where the extension has been tested to work. And on BehindTheOverlay's page in the Chrome Web Store, the developer states that a Firefox version is coming soon.
