I see that you are using the code from the Chrome browser version 84 as a basis in the Opera mini program v85.0 (last downloaded from google play). This is a very old and vulnerable version. For example, here is an elementary vulnerability in the WebRTC Leak Test definition, you can see my Local IP Address on this site https://browserleaks.com/ip
Do you fix vulnerabilities or do you just release browser versions without caring about users?
