Clicking on "Print" inside of maps.google.com opens a new window. It used to open windowed, not maximized and always in a certain size.

Firefox crashed, had to restart the PC and now this new window always opens maximized.

I want new tabs maximized (eg, clicking the + button) , but if an application opens a new window, I want it windowed, not maximized. I deleted prefs.js and localstore.rdf, the problem still persists

Firefox 24

If the page uses a script to specify certain window dimensions, then Firefox usually will honor those dimensions.

However, if the new window is launched without that information, the window typically will have the same size/state as the current window, or maybe the last closed window.

The information about window sizes and positions is stored in the same file as toolbar customizations. You can get rid of this file without doing a full Firefox reset. Here's how:

Open your current Firefox settings (AKA Firefox profile) folder using

Help > Troubleshooting Information > "Show Folder" button

Leave that window open, switch back to Firefox and Exit

Pause while Firefox finishes its cleanup, then rename localstore.rdf to something like localstore.old

Restart Firefox. Hopefully now your window behavior will be back to the default.

What is the default window size when you start Firefox?

If Firefox is maximized then un-maximize the window and set the size to you liking.
Close Firefox to save that as the default setting and check if this has worked by restarting Firefox.
