Never mind, I'm retarded and didn't check properly. Firefox refused to complete the update the first time, it needed a couple restarts to get going. Probably due to my excessive tinkering. Yes, the unload feature and everything else is present. You have to make sure that the tab you're right-clicking is loaded otherwise the option won't show up (like when restoring a previous session, the tabs stay unloaded until you actually click them).
