I did use a few of them and I am still irritated every time I run Firefox that some simple things don't (and AIUI can't) work any more. At least real ad blocking still works and they're probably not foolish enough to change that. And there are still some significant privacy advantages without the old plugins like having the option for separate search and location bars.
