Oops, you're right. I have some questions regarding fingerprinting in Firefox when using "privacy.resistFingerprinting": The window always seems to be one pixel too low. I mean, I have a screen size of 1366x768, unfortunately, but in fullscreen the browser/window size is 1366x767! Also non-maximized windows - that I use to increase entropy, sometimes - are defaulting to 1000x599. Why always one pixel too low? EDIT: It's this: When privacy.resistFingerprinting = true, set new windows to rounded dimensions [tor 19459] Guess the'll figure that out. Can I just go there and post this issue or should I do that somewhere else? Is that even an issue with their code? I mean they don't change the fullscreen-size, obviously. So why is it one pixel less there? gaaaah Also, very important: Newest Firefox totally blocks CanvasBlockers functionality when using "privacy.resistFingerprinting = true". Canvas readout will be blank and fingerprint never changes. I haven't read about that anywhere yet, so I think that is new. And I have no idea where to report that? In CanvasBlockers GituHub? In the bugzilla for resistFingerprinting? Somewhere else?
