Instagram shows "Action Blocked" for like, comment, etc

Opera always asks me if I want to open all emails in gmail and only shows "Allow" button.
50.0.2762.67 on MacOs. But this happens for couple years.

It will be also great if you add Belarus in Discover.
Opera is very popular in Belarus and this option will be very helpful for many people.
I'm ready to participate get just tell me what to do
