Introduction This Firefox Extension displays the Telegram within the Firefox sidebar. It adds a new section to the sidebar which contains the Telegram web app. It also provides a shortcut, and toggle button. How to Use Toggle the sidebar by pressing Alt+Shift+T. This shortcut can be changed by going to Add-ons -> Telegram in Sidebar -> Options. If you prefer buttons over shortcuts, there is a toolbar button you can press to toggle the sidebar. How to Unlock Firefox Sidebar Width The sidebar's width is locked by default in Firefox. Unfortunately, the sidebar is very restricted and I can only do so much to enhance the functionality of this extension. I put together a step-by-step guide on how to unlock the sidebar width on my website. Acknowledgments Icons used for all my extensions are part of UXWing's collection. Take a look at their license. Disclaimer This extension is an independent project, has no relationship, and is not affiliated to Telegram 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.
