The whole idea of a notepad is for those times when you can't find pen/paper but you have to write down a phone number quickly. This awful app insists on you fumbling around with passwords with is completely asinine.

Does not work with Firefox 61.0.2 on Mac OS X.12.6

Nice concept, bad execution. As is reported in other reviewers, Sidebar Notepad is impossible to use post-install. There is a password prompt when the sidebar is opened and a 'validate' button, the only two things usable. Regardless of what is entered, the message 'no saved password found in browser storage' is returned after hitting validate. There is no way to set a password at install or reset it. Kinda feels like a password phishing malware, though I am not making the assertion that this is what it is - just gives that impression. Would be nice if the author would respond to the complaints in comments, or even better - fix it or provides better documentation for getting this thing to work. Looks like it would meet the needs of myself and others if it were in fact usable.

"No saved password found in browser storage." I don't want a password to begin with and there's no info on how to make one.

COMPLETELY Useless. Doesn't work after initial install. NO WAY to set up a password and then the extension tells it doesn't have one stored. How inept is That ??? If you're gonna have it password protected and encrypted - there HAS to be a way to setup, store and/or edit that Password.
Completely useless.

I repeat other users complaints - unable to initially create password or do anything.

On install, I'm faced with an empty password field and a Validate button. Whatever I put into the field, on pushing the button I get a "no saved password found" message. I'm at my wit's end as to what I should do. Uninstalled.

Again, the simplest of needs – a note app in the sidebar – not catered for by the mighty "Quantum".
