Not resizing windows anymore
Despite having extensions.torbutton.resize_new_windows and extensions.torbutton.resize_on_toggle enabled, TorBrowser on Linux does not resize the window to multiples of 50px. Panopticlick reports a pretty fingerprintable browser because of that.
This behaviour has been observed on TBB version 2.2.39-3-Linux-x86_64.
In the meantime 2.3.23-alpha-1-dev seems to always return the full screen resolution.
