Using the Tor Browser, one thing I've noticed while looking at the EFF's Panopticon browser fingerprinting tool is that the screen size reported matches the dimensions of the browser window. While this makes sense in that it is ephemeral, it also results in some unique screen resolutions that are easily identifiable.
So, a couple of questions:
a) Is there a tool to resize the Tor Browser to a specified screen resolution?
b) Is there a way to force the Tor Browser to return a common screen resolution, regardless of actual browser size ?
