Regarding Firefox Browser 133.0.3 (aarch64) running on a MacBook Pro, macOS 15.0.1 (24A348): Click-and-drag movement of open windows to a different point on screen, typically toward upper left, periodically results in an automatically activated resizing of the window (to occupy more of the screen). The change is not to a full-screen mode, just larger—filling in open desktop space created by the window move. Please advise, what control can be reset to stop this unhelpful, and uninvited (now default) browser operation? Note, (1) we have searched Support posts and articles without finding an answer. And (2), the bug or glitch being queried is a serious enough aggravation in our daily work, that we will consider abandoning Firefox as a default browser if we do not find an easy, permanent solution.
