"Policy Access Control" is a browser extension that allows you to quickly change all content settings from the toolbar popup UI.
The settings for these options are all set per website (domain) basis. As a pattern, the tab URL will be shown at the top portion of the UI when you open the toolbar popup UI (e.g. http://example.com/*). Please note that any modifications are automatically saved to memory. If you want to restore the content setting changes to their default values, please click the reset button in the top toolbar.
