Thank you very much for fixing this Add-On. Does anyone have an idea how I can migrate or import my notes from the old Add-On?

Hello, great, that you work on the stuff, thank you!

But ....
a)
Notes can not still not edited in FF 70.0.1

b)
Unfortunately import from OurStickys did not work.

May you can have a look?

A big thank-you to yoasif, for salvaging Fabrizio Parrella's legacy; the only sticky notes extension that actually works like sticky notes!
