View Source of Included Files in Firefox - Easy Guide

Streamlining Access to Web Resource Code with JSView
Modern web development frequently shifts design elements away from direct HTML coding and into external CSS and Javascript files. This practice, while beneficial for organization, can complicate the process of inspecting the underlying code. A straightforward method for viewing these included files is often lacking.
Introducing the JSView Extension
The JSView extension provides a convenient solution for accessing the source code of included files in several ways. It enhances the browsing experience for developers needing to quickly examine these resources.
Default Installation and Usage
Upon installation, a new option, "View Page Source - JSView," becomes available. Selecting this option directs you to a screen similar to the standard "View Page Source" dialog.
Within the "View Source" screen, the "View" menu expands to include additional items. These new menu entries allow for rapid access to the incorporated files.
Quick Access via Context Menu
To enable quick access, navigate to the JSView Options screen through the "Tools" menu. Uncheck the "Disable jsview popup menus" option to integrate additional menu items into the default right-click context menu.
Consider disabling "Disable View Page Source - JSView" to remove the redundant JSView entry from the menu, streamlining the options available.
Right-clicking on any webpage then provides immediate access to the source code.
Additional Configuration Options
For a minimalist experience, all options can be disabled, allowing access to the functions solely through the view source window.
Users can also configure whether included files open in a new window.
Furthermore, the extension supports the use of an external editor for viewing the source code.
This extension has proven to be a valuable addition to my web development workflow. Download the JSView Extension from Mozilla Add-ons.
