Not obvious when accidentally enabled. #5
Description
When it is enabled the icon goes gray, but if you miss that all you get are content security policy errors in Firefox for all JS scripts. It would be great if when it was enabled it output a console log to tell a person it is that it is turned on in the same place it will create errors. That way id it is accidentally tripped it or set it some time ago on a site that the user is going back they don't end up ripping out their hair trying to figure out why they are getting CSP errors.
