My Tampermonkey was blocked too. There is version in opera extensions list, but it far away from new one (4.2 vs 4.7).

Is there a way to make user decide to use or not to use this blocking policy?

How to turn off auto adding 'booking.com' to an express panel? I think there's some kind of scipt which add this site to an express panel, but I don't know where to find to turn it off.
