Mozilla Firefox, as with most modern browsers give you the ability to save passwords for different websites and webpages. This makes web browsing easier, as it does allow you to easily log in to websites that you visit often.

But sometimes you want to delete these saved passwords…of websites that you don't use anymore or even to just remove the clutter.

Syncing Passwords

If you use Firefox's syncing functions to keep the passwords in sync with different instances, then the passwords should be removed from other instances once they sync up. You only have to remove passwords from one instance to delete it from all. Just make sure that sync runs first.
