Salesforce Colored Favicons

Supports both Classic and Lightning Experiences and includes separate icons for production, sandbox, and develop/scratch orgs. To use the extension, simply navigate to a Salesforce org and the extension will automatically select a random color for it then update the favicon with that color. Now every time you visit that org, the colored favicon will be displayed instead of the default Salesforce favicon. At this point you can also visit the options page to change the color for any org you've visited.
