Right now I am running 10.11.1 and Safari 9.0.1. I have Last Pass installed and yesterday in the extension panel it showed an update. So I clicked it and it asked if I wanted to get the update directly from Safari Extensions Gallery or from the Developer. I clicked from the developer and there was an update button. I clicked it but nothing happened. Sounds like a bug. Anybody have this issue or any observations on what's going on? Maybe it's some sort of operator error?
