Microsoft Online: Stay signed in de Earl Franklin

When logging in to Microsoft Online (e.g. in order to access your work email inbox), depending on the configuration, you need to go through a few steps (e.g. entering username/password, OTP).

At the very end of this flow, you are asked whether you wanted to stay signed in. For me, at least, this is always the case, and having to confirm this every time that I am logging in quickly gets tiresome.

This add-on automatically ticks the "Don't show this again" checkbox and clicks "Yes" for you, making sure that you only see the screen for a brief moment and, most importantly, that you do not need to interact with it at all.
