 Adapted from ticket #15169:

 I'm considering the idea of turning the IP address for each relay in the
 circuit display into a hyperlink that when clicked, opens a tab in the
 browser showing more information about that relay. Alternatives include:

 1.  Showing the atlas.torproject.org page or globe.torproject.org page for
 that relay. Of course, this might have privacy implications, so perhaps
 only the exit node IP address should be shown/hyperlinked?  Both atlas and
 globe require JavaScript, so it can be awkward if content JavaScript is
 disabled in Tor Browser.

 2. Extract the relay information from the control port and display it in a
 locally-generated tab. This would avoid requiring content JS, but would
 lack the pretty graphs of atlas and globe. Mike points out that if we were
 going to display our locally-generated tab in Tor Browser, we would need
 to sanitize any descriptor text to avoid XSS attacks. I see there is an
 ​HTML sanitizer utility built into Firefox.
