Is there a way to self-host an extension for Opera? Our extension uses minified and obfuscated code, which is against Opera's requirements. We already have our extension available for Firefox and Chrome — the exact same build — and would like to support Opera.
We will not unminify it because when minfied the file size is 52.42% smaller. However, we know it'll just get rejected from the Opera store. So the next best option, if possible is self-hosting.
Put it on GitHub? for local installations.
And no, you cannot host extensions from dubious locations.
However parts of an extension can be executed on a remote server.
