--------------------------------------------+--------------------------
 If a server sends the Accept-Range header + a proper content size Tor
 Browser is starting range requests that are not isolated to the URL bar
 domain. You can test this e.g. with
 https://kpdyer.com/publications/usenix2014-fte.pdf. Works even in a third
 party context with https://people.torproject.org/~gk/misc/range-request-
 test.html (your security slider level needs to be below medium-high in
 this case).
