US Patent 9870116 Controlling actions for browser extensions

A method for controlling actions for browser extensions includes registering, at a browser process module, a list of one or more rules from a browser extension, where the rules define one or more conditions and one or more corresponding actions to take when the conditions are satisfied. A renderer process module that is in communication with the browser process module applies the conditions to content of web pages rendered in the browser application. The renderer process module determines whether any of the conditions are satisfied by the content of the web pages rendered in the browser application using the renderer process module. The browser process module or the renderer process module performs the actions defined in the rules in response to at least one of the conditions defined in the rules being satisfied.
