Rated 5 out of 5 stars

Edit #2: Contacted me and gave me advice on clearing torrent folder within Firefox Profile folder. Haven't tried it since it works again, but will keep this in mind for next time.
THANK YOU Oleksandr! :)

Edit #1: Great support by dev! Reached out to me to help me figure it out. Before he could get back to me, it started working again. Don't know if he changed something or not, all I did was defrag my hard drive. Unknown whether this helped in any way.

Hi!
So far I have been a a very happy user. Since yesterday - and a Firefox crash - I am unable to display downloads/history. The tab opens and displays the following message:

The address isn't valid

The URL is not valid and cannot be loaded.

Web addresses are usually written like http://www.example.com/
Make sure that you're using forward slashes (i.e. /).

I have tried disabling, uninstalling and reinstalling but nothings helps. How can I get my view of my downloads back?
Thank you!

This review is for a previous version of the add-on (2.15).
