Extensions != Plugins

• http://www.howtogeek.com/geeknote/the-more-you-know-browser-plugins-and-extensions-aren%E2%80%99t-the-same-thing/
• Firefox is killing support for browser plugins.
• Browser Extensions Are Like Tiny Web Pages That Live In Your Browser
• Browser Plugins Are Like Automatically Opening Every File You See. Browser plugins are actually applications compiled into a special format. Instead of being a .EXE file, they are usually a .DLL file and they are loaded only by the browser. But once they are loaded they are running much like any other application on your computer, except they are used to open a video (or other) file from the website you are visiting. So when there is a security hole bad things are going to happen.
