Disable GitHub Shortcuts

This add-on disables ALL GitHub keyboard shortcuts. When the URL starts with https://github.com or its subdomains, keyboard shortcuts like "Ctrl-B" are ignored on GitHub web and delivered to Firefox. There are no settings.

In the case of "Ctrl-B", which expands/collapses file tree on code view, it is ignored and delivered to Firefox to open/close Firefox Bookmark Side bar.

This add-on blindly disables all keyboard shortcuts; for example, after the installation of this add-on,

• "Ctrl-B" in text boxes of new issues or comments will not surround words with "**" to make it bold.
• GitHub web editor will also not work.
• Moreover, Vimium, Tridactyl and other remapping add-ons will also not work on github.com and its subdomains. This is because these Web extensions capture a key press with the same API and would be in a race condition.

Currently, I have no plans to implement features like a toggle button or a shortcut to quickly disable this add-on, allow-listing of some keys, focused elements, or Firefox containers. However, any comments are welcome :) I'm not so familiar with GitHub workloads on the web interface, maybe there are some useful shortcuts worth implementing some easy way to switch the add-on behavior.
