Looking for an app or extension that would tell me if I have visited a website before. I am not looking for a historical website tracker in a searchable form like you would use to track where your kids have been. I want some type of indicator that displays if I have visited a particular site before in the past. I do a lot of research and post on a lot of forms. If I arrive at a site, I would like an instant way to be notified that I have already been here so that I can look somewhere else.
I had a custom FireFox extension written for me a few years ago. It will not work with newer versions of FireFox. I would much rather find an alternative.
