Add an option to resize the browser window to the "safe default"
I just played with my browser window, resized it, then set it to the maximum. Then a yellow line appeared, notifying me that this was an unsafe thing to do. The only option was "OK" to acknowledge the warning.
Please add an option to resize the browser window to the initial size (when I launch the browser it is always set to some default that I assume is safer due to mass usage). If possible in the menus of Firefox or whatever is behind that Onion icon and maybe also in that warning bar.
