I have an environment where I open a number of windows for my application to specific locations on the desktop. The "help" features will open a Firefox browser instance with an appropriate local url. What I would like to do is specify the same initial starting location and size for the browser window upon startup.

Is this possible through a configuration or command line option? Is it possible to "lock" the position information that is saved on browser exit? I have tried the starting the browser specifying "-height nnn -width nnn" on the command line but this does not seem to do anything.

Thanks!
