How do I remove a certificate exception I granted?

In Firefox for Android on my Samsung phone I granted a certificate exception to a site I trust. For testing I want to remove that exception but there doesn't seem to be a way to do that from the browser. How do I remove this security exception?

Best solution I've found so far: Deleting the key3.db file which also nukes all your stored passwords.

Some meta data for searches: "You have added a security exception for this site", encrypted, certificate store, firefox, android, version 21.0

Can you find a cert8.db file or a cert_override.txt file in the profile folder?

What is the path to Firefox on android? I'll keep searching but if you know it that might save time.

Unless you have a rooted phone you'll need to reset Firefox. Either by uninstalling and re-installing or by using Android's application manager in the Android Settings.

If you have a rooted phone the path would be

   /data/data/org.mozilla.firefox/files/mozilla/*.default/

That's disappointing. I figured that if I can make a change via the GUI I should be able to revert that change via the GUI again. :\

Is providing a way to manage security exceptions on the roadmap for future versions of Firefox on Android?
