There apparently no longer is an extension called 'install chrome extensions", however I opened the chrome extension store in opera and after selecting the desired extension, there's a button to "add to opera". I added the extension ok, but when the extension asks to authorize, it does not work. The extension is a password manager by F-Secure, and I would like to use it in opera. I've used opera for years, and would prefer to not have to revert to chrome. has anyone got this extension to work in opera? The extension works fine in Chrome and [ugh] Edge.
