Browser Extensions And User Snippets

Chrome Extensions And User Snippets

Most Open Source Intelligence collection techniques rely on your web browser for accessing and acquiring data. Chrome Extensions play a major role in helping extract and archive data from web pages. Extensions provide you with the “easy” button, when it comes collecting the data. User Snippets are multiline Javascript functions that you can run directly against web pages that you are trying to extract data from. 

Chrome Extensions: Are pre-made software programs that run within your browser. Extensions can be installed through the chrome store or loaded directly from your file system. Extension allow you to customize the look, feel, interactivity and functionality during your web browsing session. The Chrome store has over 180K extensions available for download. If you can think it, there is a chrome extension for it. 

User Snippets: User snippets in Chrome are a feature of the Chrome Developer Tools (DevTools) that allow developers to run Javascript programs on demand.  User Snippets can function like a recipe book for accessing and acquiring data from a variety of web sites. They can easily be reused across different websites, that use the same underlying technology. The best part about User Snippets is they can readily be modified and updated at anytime.
