If, like me, you find the Rails API documentation hard to navigate, you’ll appreciate the DevBoi sidebar extension and its Ruby on Rails addon package.
Devboi adds a sidebar to Firefox that provides access to all of Rails’ classes with nice little disclosure triangles to expand their method listings. You just double click on a class or method and it will load up the corresponding documentation page in the main window.
For more information and to download, visit the developer’s site:
