Weh Inspector is a free Chrome extension developed by ACLAP that allows users to inspect add-ons developed using the Weh (WebExtensions Helper) toolkit. With Weh Inspector, users can easily display messages exchanged between the background and content parts of an add-on, view the current content of the storage (HTML5 and WebExtensions stores), and even read and modify the add-on preferences.

To use Weh Inspector, simply right-click on the window to display the context menu and select "Weh Inspector" to open the inspector tab. The extension will automatically discover other add-ons developed using Weh and present them in a dropdown menu for easy debugging.

With its intuitive interface and comprehensive features, Weh Inspector is a must-have tool for developers who want to efficiently inspect and debug their WebExtensions add-ons.
