Nice idea, but it doesn't seem to work. Crashes or freezes FF several times in just one session and formerly highlighted sentences do not show up as highlighted upon later visits, despite the term "indelible". And FF freezes when W-M is then 'turned on' in hopes of restoring the highlights. Unusable at this point. Perhaps this add-on is not Mac-friendly?
Drag-and-drop is a rather awkward and slow method of highlighting.
The side bar gets full very quickly with noting every time a single word gets highlighted, I'm not sure what good it does to have every highlight from every page listed in the sidebar. I would prefer to just see the highlights themselves, and have something show in the sidebar only if I make a notation to it. Otherwise this method seems rather unwieldly.
