Chrome: Some websites won't let you right-click on any element, like IMDB, while others have their own menu when you right-click, like Flickr. Allow Right-Click bypasses this and gives you Google Chrome's default context menu.
There might be some pages where you want the website's original context menu, so you can whitelist these sites in the extension's options. You can also set Allow Right-Click to act aggressively on some portals, where the context-menu will be reset on div elements.
By default, you will get some ad popups from the extension once in a while, but you can disable that in the options too.
