I have an Idea.
when people walk through Internet, have a lots of things to write on notes. so its good for them that be a note section in browser to save them.
that's make them satisfy.

In Firefox desktop, you can try the add-on Notes by Firefox
It supports basic text format (accept Markdown syntax)
@tranquangphucYea this is pretty useful. Sadly, it is discontinued and no longer able to sync notes. It will be useful if we can sync those notes again.
