Upon installation, users need to go to the configuration page (about:addons) and click on Options to set the addon parameters. The extension uses YAML notations to read the parameters, providing flexibility and customization options.

One of the key features of Web Developer Sidekick is the ability to display the website environment, providing developers with a clear overview of the environment they are working on.
