I really need translation function, when can it come out?

Hey forsak3n - Anaheim released native translation. Please read about it here - https://techcommunity.microsoft.com/t5/Articles/Translate-in-Microsoft-Edge/m-p/635914

Hope you use and enjoy the feature!

Do not know when.  Can only offer https://chrome.google.com/webstore/detail/one-click-translate/anhjddeakbabimdgmonfbnpbainknbfa, at this time.  It does allow to highlight & Rt Clk > Translate, but, it is, indeed, an extension.  It's basically the same as we have with original Edge.

Cheers,
