About this Add-on
Dimming level can be controlled through the add-ons option menu.
Default behaviour can also be controlled through the add-ons option menu. This will allow the dimmer to either dim most pages or ignore most pages, leaving them un-dimmed.
Specific domains can then be configured so that pages from those domains are always dimmed or never dimmed. This is accomplished by accessing the context menu (right-click) on a web page.
