Make sure that you do not run Firefox in permanent Private Browsing mode.

• https://support.mozilla.com/kb/Private+Browsing

To see all History and Cookie settings, choose: Tools > Options > Privacy, choose the setting Firefox will: Use custom settings for history

• Deselect: [ ] "Always use private browsing mode"

"Always use private browsing mode" is cleared.

Since I've accidentally deleted the username/password, I can't get Firefox to remember it again. Another other suggestions?

Thanks, Shane.

The website may be using autocomplete=off to prevent Firefox from saving the name and password.

You can remove autocomplete=off with a bookmarklet to make Firefox save the name and password.

It's not. It had saved my username and password properly - the problem was that I accidentally deleted it. Now I can't get Firefox to remember it again.

Make sure that there aren't any entries in the Password Manager with an empty name or password field.

Also check the exceptions:

• Tools > Options > Security: Passwords: "Exceptions"

There was an entry that had a password but no username. I removed it, but the problem still persists.

There are no exceptions.

What about if I clear "Remember password for sites", and then check it again? Will I lose all of my passwords when I clear it?

It is better to export your passwords before starting to experiment.

• Password Exporter: https://addons.mozilla.org/firefox/addon/password-exporter/

Try this extension:

• Saved Password Editor: https://addons.mozilla.org/firefox/addon/saved-password-editor/

I checked the HTML source again, and there is now an autocomplete="off" attribute on the password field. This attribute must have appeared after I originally saved the password. Now that I've accidentally deleted the username and password, though, Firefox won't let me save it again.

I'm sorry for the trouble. I should have been keeping a closer watch on the HTML source.
