"How often does Tor change its paths?" entry is wrong
https://support.torproject.org/about/change-paths/
says
"Tor will reuse the same circuit for new TCP streams for 10 minutes, as long as the circuit is working fine."
and that is true for little-t-tor but it stopped being true for Tor Browser some years ago when Tor Browser switched to configuring its tor with the KeepAliveIsolateSOCKSAuth isolation flag.
After that point, the way Tor Browser works is that it keeps the same path for a given first party domain (think "domain in url bar") so long as you have an active stream on it within the past ten minutes. This is also the same behavior Tor already had for connections to onion services (since onion service circuits are expensive to rotate).
The reasoning for sticking to the same path for a given destination is that rotating only increases the surface area, exposing information to new relays and new pieces of the internet.
