Fastmail in Sidebar per semanticdata

A Firefox Extension to display Fastmail within the Firefox sidebar. This extension adds a new section to the sidebar which contains the Fastmail web app. It also adds a shortcut, and a button toggle within the toolbar.

How to Use

1. Toggle the sidebar by pressing Alt+Shift+F. This shortcut can be changed by going to Add-ons -> Fastmail in Sidebar -> Options.
2. 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.

Disclaimer
This Add-on is primarily for personal use; a personal project if you will. I'm just trying to use Fastmail on the Firefox sidebar. This add-on just launches their webapp in the sidebar. This extension is an independent project, has no relationship, and is not affiliated to Fastmail in any way.
