Is there a way to set a default “New Window” size in Firefox? It seems to use the size of the last window open, but sometimes it gets stuck on a size and won’t change. A few days ago I needed to use a window that was very small, and now every new window is that size. At other times I’ve gotten full-screen windows that I only use with Google Maps. It’s a real pain in the ass to have to re-size every new window. It would be very useful to be able to establish a default size that would override all other sizes. Is there a way to do this? ---

I use Firesizer, and it’s pretty good. I wish it locked, so you can’t accidentally resize with a stray mouse click, but otherwise it’s really good.
