How do I migrate if it's a google extension?

Sure, do some research and this is the only way at the moment using the chrome api

Let there be a popup window, and return the url with the token. The question that does not support it for example in Opera. I don’t know if it’s because I’m in developer mode. Look in opera and nothing.

So I’m seeing what I do, I’m going to try to find another way to open a pop-up window or else copy and paste.

Maybe I’m in development mode, hopefully that’s why. And using the extension in opera.

I imagine that if I publish it and then download it, it will work for me. (Because I understand that Opera supports it). Hopefully it will be like that.
