This extension allows you to choose different passwords for each website which requires an account without having to remember all of them. The extension achieves this by taking your master password and hashing it based on the website's domain (e.g. the google in to create a password that is unique to that website.

Quickstart Guide:
0a) First time only: check that site settings are correct and that you have enabled compatibility mode if you're coming from the old Firefox plugin.
0b) First time only: check the global settings in the options page of the extension to choose your password length.
1) Input your master password in the password field
2) Press the '#' button near the password field or use Ctrl+# to hash the password in place
3) Optional: Use the '*' button or press Ctrl+* to check either your master password or the hash word (depending on whether you've hashed your master password already or not).
4) Login

Password Hasher Plus is a replacement for the Password Hasher extension which unfortunately is not developed anymore and does not work correctly with multi-process Firefox and not at all with Firefox Quantum.

To generate hash words which are identical to the old version, you have to enable compatibility mode!
If you were using custom settings for the hash word you can use password strength "Custom" to select the options you were using. Note that "digits only" is present as strength "Numeric".

Risk impact

Password Hasher Plus - Password Generator requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install Password Hasher Plus - Password Generator if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Password Hasher Plus - Password Generator has earned a fairly good reputation and likely can be trusted.

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on, especially ones with higher risk impact and/or higher risk likelihood.

The plugin is slowing Firefox. Its GUI is too confuse, intrusive and shortcut keys isn't working.
