Ah, sorry, there's been a misunderstanding here. After some more recent changes to improve robustness of clearsing site data "Forget About this Site" indeed does delete AppCache, because it hits this function: https://searchfox.org/mozilla-central/rev/2c912888e3b7ae4baf161d98d7a01434f31830aa/toolkit/components/cleardata/ClearDataService.jsm#285 Now, that is also not really what it's supposed to do, because that deletes all AppCache, not just the one from the host that Forget about this Site passes. I should have clarified that that is what we want to fix in the bug title. Considering that we'd like to get rid of AppCache, it's probably fine to leave this closed, though.
