Protects sensitive data in web pages and applications by masking text and images. Useful for demos in production systems with real data and for recording screencasts. You can set an URL to be matched and the CSS selectors of any kind of HTML element.

Imagine you have a web application or tool that you want to show to potential leads in webinars, on a trade exhibition or you want to record a screencast.
Doing this with personal data of users breaks privacy requirements or GDPR laws (unless you have their consent).

You could setup a staging system with mock-data, but we all know how much effort that means as well as keeping things in sync (even with good Dev-Ops processes).

This extension takes your application, and masks/obfuscates all text fields and images that match the given selectors (they work like CSS selectors). Problem solved!

Choosing the right selectors requires a little bit of HTML knowledge:
You either look at the source code of the page (with the web console) and find out the single ID or a class for the elements, or you tell the developer of the application to add a specific class to all fields that contain personal data, that needs to be masked.
