Firefox Theme Changer

A small extension that lets you change Firefox's theme at runtime just by creating a file.

Installation

• Install the extension to Firefox
• Clone the repo
• Copy themechanger.json to the proper Manifest Location. In linux, this is in the ~/.mozilla/native-messaging-hosts/ folder.
• Change the path inside the file to wherever you want to put the firefox_theme_changer.py script.

Usage

Once everything is set up, you can change the theme by creating a file called firefox_theme containing the name of your desired theme (the same as in the Firefox screen), in the same folder as firefox_theme_changer.py. Remember it'll only work if the theme is installed.
