WhatsApp Pinned by SemanticData

Introduction
This Firefox Extension opens or toggles WhatsApp Web within a pinned tab. It also provides a customizable keyboard shortcut, and toggle button.

How to Use
Toggle the pinend tab by pressing Alt+Shift+W. This shortcut can be changed by going to Add-ons -> WhatsApp in Sidebar -> Options. If you prefer buttons over shortcuts, there is a toolbar button you can press to toggle the pined tab.

This extension is an independent project, has no relationship, and is not affiliated to WhatsApp or Meta in any way. This extension is primarily for personal use; a personal project if you will. This add-on only launches their web app in the sidebar.
