The main thing I use Incognito for is here on the bbs—if I want to read something that’s ahead of where I’ve read to so far in a topic, without losing my place in that topic notification-wise. E.g., if someone links to a post in a different topic that I haven’t started reading yet, I’ll follow the link using Incognito.
(bbs user Ignatius suggested that trick to me, and I will always be grateful to them for it. They haven’t been around for a few years, though, so I’m not going to @ them.)
