Does not work Ubuntu 19.10 - Opera Dev 67.0.3564.0

[mellofellow]

None of the Chrome store extensions work.
Seems to load into Opera OK (in .config directory).
But on the actual install page in Opera, clicking "Install" does nothing.

Opera extensions work just fine.

Same problem. Chrome extension installs but nothing from the chrome store works. It opens opera extension to asking you to install whatever extension but it never appears.
