Downoaded Opera extension 188.8.131.52 from the 1pw mini but don't see it anywhere in the toolbar of opera 49.0.2725.64

Found that I had to accept the extension in the extensions pane, accepted it and it is there now
Ah, indeed. Opera prompts you to enable the extension after installing it, but if you dismiss that you'll still need to do that later manually:
Anyway, glad you were able to sort it out. Cheers!
