I expand it by grabbing the bottom right and getting the size I want. It stays there until I shut down and later restart my Mac. Reverts to default window size. Nothing in system configuration has changed. Not resolution, view setting, etc. Windows in other apps stay where the user (me) has set them. I have searched to see if this has been reported but to-date I cannot find someone experiencing the same issue. Is it the end of the world? No. Is it a PITA? Well...</P><P>Throughout many years of using Firefox it retained custom settings such as window size. Not sure what has happened here. Thank you in advance for any advice.</P> Tue, 05 May 2026 21:27:17 GMT marcehanes 2026-05-05T21:27:17Z https://connect.mozilla.org/t5/discussions/firefox-browser-defaults-to-original-size-version-150-0-1-mac-os/m-p/124639#M49147 <P>For what seems like the past few weeks Firefox reverts to its "default" window size of roughly 15x10.
