@fefplays Not possible as far as I know

@celticyoshi dont know but . they sould give us persion to add by us . the messengers.. but for now no way for it

I'm new to opera, I've never been to facebook (don't have an account) but like everyone else messenger keeps adding itself back to my sidebar. Not expecting a fix just adding to the list of people who are having this happen, will be switching browsers if it keeps happening.
