Definitely not as good as the now-discontinued Microsoft extension. Biggest issue is this extension displays non-existent OneNote notebooks with duplicate names of existing notebooks.
I applause at the effort of stepping up when Microsoft dumps Firefox. Unfortunately, this extension does not work for me. It fails with a "forbidden request" error message when connection my OneNote account. I use the Office 365 version of OneNote, that might be the issue here.
The 'Forbidden Request' issue when linking to OneNote (Office 365) has been resolved. With the latest update (v0.0.18), we’ve added support for Office 365 accounts. Extension should auto-update. please give it another try, and let us know if you encounter any further issues.
