The master password works for the webpage and also on my mobile (iphone), though I cannot open my browser plug in Mozilla.
I can no longer access the browser plugin (initially I could but with an older password( previous one in webpage). I already tried changing the password in web page, restarting the computer.
When you say “in web page” (as in, ‘(initially I could but with an older password( previous one in webpage)’ what exactly do you mean by that? Do you have your web browser saving passwords, is that what you are referring to?
