Does not seem to work? When I activate it, it'll give me a pop-up to set up a password and once I click ok, that's it. It says it's activated but won't ask me set a limit or put up a timer. I cannot find info about how to set a limit either. I can only activate and deactivate. Update to respond to Developer: I was using it on tumblr and it did nothing even with multiple refreshes. I also tried it on ao3 to see if that did anything. It did not.
