Often the URL for a site for whose login/password I need to search is not named the same as the site itself. Being able to a "title" the login entry, or add tags, would allow more effective searching.
Example: I am trying to find my account for "Groucho's Ford Dealership", but the actual URL is "https://vehicle.syndicate.cloud.com/dealer3780". I might never find my login.
Secondly, I don't think that firefox preserves URL parameters in the saved login entry. If the above example where "vehicle.syndicate.cloud.com?dealer=3780", I would again have a harder time finding Groucho's site (not knowing his dealer number).
thanks.
