Sorry but this is absolute rubbish!!
For users with OneNote client installed, we just need something to pass the web page to the client directly. For the use of onenote.com, there is a direct API that can be used.

NO EXTERNAL APPLICATION SHOULD BE REQUIRED!!!!

Immediately deleted.

I understand from the developers comments that there is a "Legacy" version - to me this implies a version that is no longer under active development or use & therefore is not something that I'd want to commit to.

UPDATE: Thanks to the dev for replying to me. However, the constant recommendation to use a "legacy" addon is not comforting I'm afraid which is what I said above. The solution IS rubbish sadly since there is no need for another piece of software to be running on my PC with all the possible stability and security issues it could bring.

Instead, I've added the "Clip to OneNote" bookmarklet from Microsoft. Although not perfect, it works without additional software installation.
