 Thanks!

 settings button. What does it mean? (The tooltip only says "Tor Enabled")

 8.0a10 is not released yet, thus you get the warning icon that indicates
 you are running a non-approved (and possibly dangerous to use Tor
 Browser).

 blocking content allows fingerprinting], instead
 [[comment:4:ticket:12958|you suggest]] "an identical blocklist for every
 user. For example, AdBlock Plus with a fixed set of filters." Do you have
 plans to do this?

 No.

 Panopticlick is not a good platform to test Tor Browser for fingerprinting
 resistance on because of its bias due to older browser configurations and
 all the other browsers that are in the database and which your values are
 checked against to find out the uniqueness of your configuration. Re your
 screen size: do you get that with a clean, new 8.0a10 without any
 modifications? You should have a config rounded to a multiple of 200x100.
