A Visual Studio Code extension to provide an environment to develop Firefox userChrome.css.
CSS snippets are sourced from Mozilla’s gecko-dev repository, updated daily at 00:00 UTC. Users can select a source branch (beta, master, or release) based on their preference.
Automatically launch Firefox whenever userChrome.css is saved. If Firefox is already open, the existing process can be closed to apply changes before relaunching.
This feature is only supported on Windows. There is no technical reason why this feature cannot support Linux or Mac in future.
Easily open and existing userChrome.css or create if the file does not exist for your chosen Firefox profile. The appropriate profile is likely the most recently modified profile.
