Does not support Firefox Quantum (Firefox 57), and is not expected to in the near future. If you are a developer who wishes to help update Internote to the new extension system, please email me with a clear subject line.
To restore Internote, you must downgrade to Firefox 56. Pay particular attention to the section about preferences.
Internote allows you to create useful and private notes on webpages which will be there once you return. With Internote, you can do many things. Move, resize, recolor, minimize, import, export, print, delete your notes ... choose the pages where a note appears ... or manage them all at once.
Is your sticky notes extension secure? Many such extensions claim to be secure but insert your notes into the webpage to display them. This means that if the webpage is looking, it can potentially capture your notes and transmit them off your computer. Internote displays your notes in a layer over the top of the webpage, so it'll never know they're there, and you'll never know the difference. Ask the authors of other extensions whether their extension is secure or playing fast and loose with your privacy.
Internote3 includes new features such as minimized notes, the ability to specify the set of pages on which a note appears, an improved manager, better robustness and extendability, and much more!
