If you take advantage of Firefox’s ability to save passwords and prefill them on certain web pages, eventually you will have a bunch of dead or out of date entries. It is good idea to occasionally review and clean them out. Here is how (Firefox 3):
- Go to Tools > Options.
- Security tab > click Saved Passwords.
- Click Show Passwords. It is good to show the passwords in the event you have multiple entries and some are not correct.
- Highlight and remove the dead entries.
That’s it. While keeping your saved passwords list clean isn’t going to give you a performance increase, it is overall good maintenance to perform on your Firefox browser.
