Analyzing communications APIs in browser extensions

Enter your manifest file first. Then hit parse. The manifest will be parsed in order to suggest the different components of your extension. To specify the code of a component, add the code to the text editor and simply hit the name of the component. When the code of a component is provided, then the component is colored in green. When you are done hit the "Analyze Extension" button to analyze the communication APIs of your extension. At the end of the analysis, sensitive APIs that can be potentially escalated will be displayed in the editor

This tool will not analyze dynamically injected content scripts.
