It's just regular html/javascript.
Code: Select all
<label class="sr-only" for="username"> … </label>
<input id="username" type="text" placeholder="Username" name="username"></input>
<label class="sr-only" for="password"> … </label>
<input id="password" type="password" autocomplete="off" placeholder="Password" name="password" pwfprops=","></input>
Please note that if pale Moon has multiple logins for a site, it will not automatically fill in the details - you have to let the form filler kick in by entering part of your login and selecting the correct one from the drop-down. Also, your privacy settings may prevent automatic form-filling.
If the problem is that it never offers to save these details in the first place, then that is likely because the login process is not using normal form submission (to which the password manager is linked).
Also, note that "autocomplete=off" is mentioned. Even though Pale Moon should ignore this on password fields in the most recent versions, on older version it will prevent passwords from being filled in. If you are not on the latest version of Pale Moon, try upgrading first.
