## Further Hardening

- For further hardening of Firefox Beta and Fennec, check out [arkenfox user.js](https://github.com/arkenfox/user.js).

NOTE 1: To use user.js, place it in
- Firefox Beta: `/data/data/org.mozilla.firefox_beta/files/mozilla/<profile name>.default/`
- Fennec: `/data/data/org.mozilla.fennec_fdroid/files/mozilla/<profile name>.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
