Can not copy message content to messenger (facebook)

[Debugger]

Can not copy message content to messenger (facebook).
After selecting the text, it automatically deselects the text! So how can I copy any message?

EDIT:
I can only select/copy one message, I can not, for example, select/copy the last two messages or more.

URL to this FB page?

I guess @debugger is asking about FB's messenger.com.

Is that someone can just "access" - without having a FB account (or something like that)?

(Yep, that's me. I don't belong to that 1.74 billion club.)

Hm.No. I'm talking about this simple communicator on FB.
