Rated 5 out of 5 stars

That's all I said after opening the Tools>FromWhereToWhere tab. Wow!
You don't know how many times I've wanted this kind of information!!! Or perhaps you do, which is why you made this killer plugin! thank you!

This review is for a previous version of the add-on (0.19.1). 

Thanks for the support and encouragement. You don't know what a pleasure it is for me to see --- instead of just hoping --- someone out there actually finds it useful.
I was thrilled to find that the information is recorded in Firefox history all along without making good use of, and I feel obliged to make it happen as the addons performing similar function that I know (like "Referrer History") are no longer available for current FF.
Though there are already some possible improvements in my mind, I would appreciate any suggestion from you, an actual user's perspective.
