Discord in Sidebar is a Firefox extension designed to integrate the Discord web app directly into the Firefox sidebar. This extension enhances user experience by allowing easy access to Discord functionalities without leaving the current browsing session. Users can toggle the sidebar using a customizable keyboard shortcut or a toolbar button, making it convenient to manage their social interactions while browsing.

The extension also addresses the default width limitation of the Firefox sidebar, providing a step-by-step guide for users who wish to unlock the sidebar's width for a better display. It is important to note that this extension is an independent project and does not have any affiliation with Discord, serving primarily as a personal enhancement tool for users who frequently utilize Discord.
