Tabatha New Tab
This is a Firefox addon and a Chrome extension that replaces the current new tab and homepage with a sleek flat black design.
The settings modal is a bit crude, but it gets the job done for enabling/disabling and configuring the temperature display.

There is a hosted copy of the same application that runs in the extension hosted on tab.dstn.to if you would like to see what it looks like.
To run the extension yourself clone it, install the packages by running
yarn in the project root, then run
yarn dev and it will proceed to run the extension in a test firefox instance.
