Behind The Overlay Revival — Iván Ruvalcaba

What's it all about?

This is a fork of Behind The Overlay add-on, ported as web extension as well as some improvements implemented.

Some websites will use an overlay to mask its content with a transparent background to force you to read a message before you can see the actual content.

I find this very annoying as every site will have a different way to close that overlay popup.

This extension solves this problem by offering you one button to close any overlay on any website you may ever encounter.

Features

• Requires no special permissions. The following are the permissions required by this add-on:
  • tab and activeTab: Required to determine whether or not to display the action icons for the address bar and context menu each time a website is visited exclusively through the http and https protocols.
  • menus: Required to display context menu entries.
  • storage: Required to save locally the user options.
• Extremely lightweight, relies on little known document.elementFromPoint browser's function to find elements that are in front with the highest z-index.
• Non-intrusive. The extension activates only when you click its button, thereby it has no impact on navigation performance when you don't use the extension. Doesn't inject tons of CSS rules as AdBlock extension is doing for example.
• Supports hiding of multiple DOM overlay elements.
• Enables overflow auto of the body when overlay script hides it to disable the scroll of the page.
