Hello. I have been using focus for quite a long time. I am a Network engineer, I want you to know this first. I see some missing points for myself. They are as follows: 1. The application is very weak on ad blocking. Many browsers have a built-in ad blocker. But this Firefox focus does not exist. Sad. 2. I use it with a vpn. But the fingerprint (browser language ) looks the same as on many ip address sites. This definitely needs to be improved. For privacy and complete security, this problem should definitely be solved. That's all for now. Have a nice day.
