I tried your Docker FireFox, and I don't know how you did this, but this is very seamless. I mean, the other Docker GUI app I have tried required me to connect to the desktop inside of Docker using a VNC client, but yours just needed a web browser, so it was much more convenient and the resolution was automatically set to fit the browser.
Anyway, if you could make this for FireFox, I think making the same thing for Opera is probably similar, because Opera is another web browser. I occasionally use Opera for its free VPN and nothing more, and Opera on Windows keeps creating unwanted shortcuts, so that sucks. Also, on Linux, it does not support Wayland, so there are numerous problems to use it natively on a Wayland desktop.
