Further Hardening

• For further hardening of Firefox Beta and Fennec, check out arkenfox user.js.

NOTE 1: To use user.js, place it in

• Firefox Beta: /data/data/org.mozilla.firefox_beta/files/mozilla/SomeAlphanumericText.default/
• Fennec: /data/data/org.mozilla.fennec_fdroid/files/mozilla/SomeAlphanumericText.default/

Check the permissions for pref.js already present in that path and give the same permissions to user.js

NOTE 2:

• Root access is required for placing user.js in above mentioned path and changing permissions.
• Users without root access can change each and every setting manually in about:config
