Make Firefox Remember Any Password, No Bookmarklet Required

The CyberNet blog previously showed us how to make Firefox remember any password, even for high-security websites that prevent password saving. That hack doesn't always work in Firefox 3, but they've got another solution. By changing one value in a Firefox configuration file—found at C:\Program Files\Mozilla Firefox\components\nsLoginManager.js in Windows, and Firefox.app\Contents\MacOS\components\nsLoginManager.js on Macs (the location will vary for Linux users, best to search for it), you can have Firefox ignore any flags thrown down by websites to prevent password saving. CyberNet walks through the nitty-gritty of the code change and how to undo it, but it's worth stating again that you'll only want to do this if you've got other systems in place to secure your saved passwords.
