hello, websites can specify if browsers should be able to save username/passwords (through the autocomplete="off" attribute in the login form in the html source code) - this is often the case when a higher level of security is presumably required by those sites.

you can either install an addon or use a bookmarklet to circumvent this restriction.

Usernames and passwords are not saved

Thanks, still but searching

You're searching for a password editor? Maybe: https://addons.mozilla.org/en-US/firefox/addon/saved-password-editor/ (I don't use it myself)

The password editor is the bomb. It is so easy and solves the problem. The coolest thing it does: you can go to the page you want to have it remember and pick New and then Guess from Current Page. Then enter the login and pw and you're good to go Very efficient.
