Github VS Code One Dark Vivid with Fira Code is a Chrome add-on developed by ljosberinn. This add-on aims to change the appearance of Github's code to closely resemble the One Dark Vivid theme of Visual Studio Code. It is built upon the vovanmix/github-dark-theme.

It is important to note that in order to use this add-on, you must have Fira Code installed locally. You can download and install Fira Code from the official website. If you encounter any issues during the installation process, the Fira Code website provides troubleshooting information.

If you feel that more colors should be added, you have the option to open a pull request to suggest the changes. Additionally, fonts need to be added to the /src/code.less file on line 5, with a fallback for macOS and Windows.

The color scheme of this add-on is based on the One Dark Vivid theme available on the Visual Studio Marketplace.
