Really wish this extension would work. Tried it on about six websites and it only revealed the password by hovering over the password field on two of the sites. Haven't found any extension for FF that will do this. ShowPassword for Chrome-based browsers works 100% of the time. Will come back and check on this again later.

Hello Dan,

Here are some websites where the password is not displayed when I hover the mouse pointer over it.

https://accounts.google.com
https://account.proton.me/login
https://nextdoor.com/
https://www.tivo.com/
https://myaccountrwd.allstate.com/anon/account/login
https://www.wheeloffortune.com/

Your extension works for most websites I've gone to, just a few where it doesn't. Thanks.
