Works just fine, but it lacks one important feature:
With this addon you have to use exactly two fields (f.e. username and password), but there are sites out there with just one field (f.e. log in to a router with just a password) or with more than two fields (f.e. log in to a bank account with a number, username and password).
With this it would be a great addon!
It would be nice to have that, and we would, if Mozilla's Password Manager supported it (which it doesn't), or if Saved Password Editor were itself a password manager, as opposed to an enhancement for the built-in password manager.
If I ever write something like that, it will most likely be a different add-on.
To create your own collections, you must have a Mozilla Add-ons account.
