Add hyperlinks in tor circuit display to show "more info" about relays
Adapted from ticket legacy/trac#15169 (moved):
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:
-
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.
-
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.
