Hello, I have problem with new Opera builds, I force them to save pages as mhtml by adding "--save-page-as-mhtml=1" to launcher.exe, ...
You don't have to force Opera to save page as mhtml, that feature is still there - latest Opera version.
The page you gave as an example - can't save it either, must be some restriction on their side.
