Hi,

I want to control the window size of Firefox browser and whether a plugin is enabled or disabled when a new firefox browser is opened.

Currently I'm using a Tor browser which is a modified firefox browser, when I open it, the window size is set by default and flash plugin is by default disabled. even if I try to set them mannually, the next time I open a new firefox window, the setting return to default. I want to know which configuration files or what part of the source codes are controling this default setting, and I want to modify it.

can anybody give me some solution or hints? thanks!
