using? having! better uninstall them all, confine them into firefox if you still need them.
don't forget to get rid of the 3 iconless meta apps either that are installed to lots of phones from the factory:
- Meta App Installer
- Meta App Manager
- Meta Services
you can only see these in the settings, installed apps list, after finding the hidden option to also show system apps.
App Manager or similar tools will also show them.
