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.

Looks nice. Helpful aid. But what do the slice sizes in pie charts mean? Are they time spent on that site, or the number of visits, or ...? And why is the % for a site dependent on whether I view by title or domain?

Nice extension, but it only shows your activity from the last few days.

Thanks good addon, but it'll be better if we can open history master page by ctrl+h instead firefox builtin history sidebar. Also it'll be good if analysis is done by main domain/parent domain and not by page-to-page.
