1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
2. Click I'll be careful, I promise!, to continue to the about:config page.

Then search thh string "security. ask_for_password". Click twice and then insert 0 (zero). Then restart firefox

It's already set to 1 & i don't believe is the correct preference to Lock & disable (grayed out) a master password.

lockPref("pref.privacy.disable_button.set_master_password", true);

This worked in the older versions but doesn't apply for 17.0.9 ESR version

There doesn't seem to be a pref connected to this check box.

Would you happen to know how to disable this even though there isnt a pref tied to it?

Mike Kaply has written a lot of articles about how to configure Firefox and is also the creator of the CCK extension. Maybe he knows a way to accomplish this.
