@ferhatsteel Hi Sir, From my point of view I think there is no need of extensions or add ons because opera have basic functionality on its own. For what we need extensions. It has adblocker, VPN, Data saving, Private browsing, password manager and so on. And the second thing add ons have there own privacy policy and terms of use so it is better to avoiding them because some of them are not as secure as opera. Thank you.
