I had great hopes for this app since OneNote Web Clipper was discontinued for Firefox 138.03. Unfortunately my hopes were dashed since oneClipper is unable to connect to my valid Microsoft account. Removing. Hope you get this bug fixed.

It does not work at all. After I connected it to my account, the AddOn at the side panel is just white with starting letters of my sections. If I resize the panel, I can see other windows behind it?? It is all jumbled together in one window somehow... In the top right, if I press on Sections dropdown, I just get a big dark grey window with QuickNotes to select. Apart from that, I cannot do any thing else. I cannot select where I want the notes to go. I wish I could upload a screenshot here to show this weird behaviour.

The developer has done an exceptional job addressing bugs and significantly improving the extension in just a few days.
Please include sticky notes feature

Newest update was big step forward. Great tool. thanx.

UPDATED: This is a great alternative to Microsoft's discontinued OneNote web clipper. The UI seems a bit clunky at times, but the developer is very responsive to feedback and bug reports, and fixes things quickly. I've updated my score from 3 stars to 5.

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.

fast fix!

Works pretty well! Nice to have a dedicated addon for Onenote back on Firefox. The only issue is the icon for the addon doesn't show when you pin it to the toolbar in the firefox, but this appears to be an issue under investigation (according to the github support site). This doesn't seem to stop the addon from functioning as it should.

In fact it is possible to clip into any notebook, maybe I overlooked it last time, or it's been updated. Either way, it's working quite well.

This does do what it claims to able to do, and since the original Microsoft addon has been removed from Mozilla under mysterious circumstances, I'm glad to have it.

I've deducted a star as it seems to be unable to find anything but the first notebook in alphabetical order if you have multiple notebooks. Any clippings that are intended for other notebooks have to be moved in OneNote after being saved in that top-most notebook. However an option to save in sub-sections of that notebook is available.
