Re: [tbb-dev] TBB 6.0.5 / screen resolution and color depth

Spoofing the window consistently is probably not possible as there are numerous ways to find out the dimensions of your actual window size. Thus, making sure you get a properly rounded window size seems to be the easier route to mitigate fingerprinting.

where and how is this controlled though? in a default firefox window, the test site reports back my actual screen resolution, no matter what size the window is. it seems TBB is doing some spoofing somewhere but it is always returning the size of the window. 1000x500 is not a screen resolution used anywhere, so if TBB starts with a window size of 1000x500 we can almost be certain that it is a Tor Browser and not blending in with other clients
