A minimal GruvBox theme for Firefox
This is a Medium Dark Gruvbox theme though I am working on including the hard, medium, and dark flavors of the light and dark varients in the future. The palette I used can be found here.
If you don't want to use the native Firefox extention which can be found here, you can download the release and sign & upload for personal use. You can also download the source, alter it, and use the makefile to zip it automatically and upload it.
Hope you enjoy.
