Firefox not remembering the last window size? This may fix it!
By: ghack.netoriginally appeared on
Some months ago, I started to notice that the Firefox web browser was not remembering its window size when closed and reopened.
I usually run Firefox on one half of the screen on a 1920×1080 monitor on a Windows PC. Firefox would open and by doing so, change its window size so that a small gap was left at the bottom of the browser window and the Windows taskbar.
While it is easy enough to make the browser fit the space, e.g. by dragging its window to the left side of the monitor to have it expand automatically, it was something that left me puzzled.
It did not really bother me too much but when a user on Reddit pointed to a possible solution, I had to try it to see if the proposed solution would fix the issue on my end.
