About

Each host can have a banner with different colour and text.

I'm a developer who works on a number of products where the dev, test, uat and prod environments all look the same, so I made this extension to make it easier to see where I am.

Copy and paste a url into the extension, set a banner colour and text, and then when you go to any page on that host, the banner will be displayed. There are a couple of different positioning options to help ensure it will work on most sites.
