This extensions show a bit of data, but it does not seem to show all of my visited pages history that are weeks/months ago. I even imported the history from Edge to Firefox, still the extension does not get/record all those pages. So, I don't know if it's really that limited or broken. Maybe this extension needs to be fixed so it can check all of my history and get massive data to record. I really hope it will be like History Trend Unlimited addon.
