A comparison:
Quicknote: select text; rightclick; add note
QuickFox: select; rightclick; select notebook; add note
Quicknote has a side pane which is convenient for side by side editing.
QuickFox has the ability to add more notes and sync with web storage.
I think to manage lots of note, zim wiki or emacs org mode are better, you can include graphics and tags, so note add-on in firefox is just a temperary storage, the quicker the better.

Suggestion: middle click on selected text to add note

Thank you for this tool.
