moz60tool is a tool for checking your JS source code to see if you are using any Mozilla-specific extensions that will be removed in SpiderMonkey 60. It was written by Philip Chimento (@ptomato) and licensed MIT.

This extension is a small wrapper around moz60tool, allowing you to easily check installed extensions for deprecated code. It should be compatible with Gnome Shell 3.26+, but probably won't work on older versions.

If you discover an extension containing deprecated code that isn't yours, consider reporting it to that extension's maintainer.
