Great Extension, Probably Doesn't Do What You Think It Does.

This extension is not meant to lock down Firefox with a password. It is a workaround for a Firefox bug.

If you use Firefox's built-in Password Manager, you probably set a master password to protect your stored logins. But restoring a tab session can trigger a bunch of requests to unlock the password manager. This extension lets you unlock the password manager early so that you only get asked once. It's very handy for this purpose.

This review is for a previous version of the add-on (1.1).
