I have been noticing for a while that there is a hidden opera authored extension 'enegjkbbakeegngfapepobipndnebkdk' for capitaloneshopping that can't be disabled.

This 'rougue' extension seems to get launched discreetly & then closed every time for every interaction made on opera. This despite the fact that i had disabled cash back setting in the settings a while back (in the current version the setting is not there only the one related to 'Show cashback badge in all workspaces' is present which is off)

My question is why is this extension getting triggered to do something on every interaction, what is the justification for this?

Why isn't this privacy intrusion stated clearly anywhere?

Is there a way to disable this in any way?

Thanks
