I got Opera version 92.0.4561.33 on my Windows 10 recently, everything is working like they're supposed to with nothing blocked away from my IP, except for the add-on "Install Chrome Extensions".
I cannot access it through the browser itself, nor any other platforms like the mobile, and not even other browsers like Firefox and Chrome.
Every other add-on can be browsed and installed properly, except "ICE", is there anything to help?
