A little help for when you install this extension:

1. Change "Force dark mode on pages" (or something like that) to On
2. Open the extension in the sidebar
3. Press the settings icon on the top right
4. In the extension's settings page, change "Button Space" to 0.24 (or any value that makes the buttons align)
5. Done!

Note that whenever you need to use it, change "Force dark mode on pages" to on.

Doesn't work anymore. The QR code doesn't show up.
