Policy Control is an addon that helps you easily adjust all content settings (via contentSettings API) from the toolbar popup UI.
These settings are adjusted per website (domain) basis. Once you open the toolbar popup UI, the tab URL will be appeared at the top section in the UI as a pattern (i.e. http://example.com/*). Adjust what you need for this pattern and then reload the webpage. Please note, all changes are auto-saved to the memory. If you want to reset the content setting changes to the default values, please press the reset button at the top toolbar.
