Pavol, I downloaded Opera and maximised its window. I agree, there are no minimise or maximise buttons unlike with other applications. Is this an issue with Opera or with Ubuntu? If this is an issue with Opera then the problem cannot be reported here. If this is an Ubuntu issue then it needs to be filed against the offending package.
I've yet to find another application that doesn't display maximise and minimise buttons when maximised. It's easy enough to get around, just double mouse click Opera's top bar and the buttons become visible. In any case not a Firefox bug as your report suggested. Marking as incomplete awaiting your input and suggestion as to which Ubuntu package is at fault although a quick "Google" suggests that this is an Opera issue which needs to be reported to and fixed by the Opera developers. ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775000 Title: Opera web-browser.
