Add-on does not work and lock "Preferences" in Firefox anymore from v.37 & up

Yes, on Firefox 38, when I go Options, it opens a new preferences tab (about:preferences) instead of asking for publicfox password.
Please fix ASAP and also make it compatible with older version as it is now.
Would be nice if you can also block About Firefox menu, to prevent Firefox update.
Thanks a lot!

Yes please fix this! Have Firefox on some public computers and need to keep users from seeing the password for a paid database. Also from messing around with things in general.

As a temporary measure:
to solve this problem restoring the classic start menu settings
in about:config, find "browser.preferences.inContent" and set the value to "false"
after restarting firefox addon starts to work correctly.
tested on firefox version 40.0.2

Hello,

Is there any update on this issue? I work in a public access computer lab and we have been relying on Public Fox to lock down our Firefox installations. Thank you!

We are currently running version 41.0.2 of Firefox, and the "browser.preferences.inContent" setting @alan8wolker mentioned works perfectly! However, that setting does not exist in the latest version of Firefox (43.0.3 at the time of this writing).
