This extension is a clean implementation to re-enable right-click context menu on websites that prevent it. Some websites prevent right-click to prohibit the user from copying or pasting content. This is a misuse of a browser feature that is designed to allow website owners to provide their own context menu not to block the user from accessing the browser's default context.
How to use the extension?
Simply click on the toolbar button if the right-click is blocked on a website. That's it! Note that this extension uses a non-persistent background script which means it is not using any resource unless the toolbar button is pressed. So compared to the other alternatives it can be considered more efficient implementation.
