It was great, but now it's not working anymore....

This was the best addon to firefox, but now it stopped working. Did send a mail to suppot but they do not answer. Please fix it and it will be 5 star review for sure!

It was a basic add-on, but it doesn't work anymore.

I keep getting this message: Unable to load your list. Taking too much time" That may not be verbatim, but it amounts to the same thing. I've shut down all of my ad-blockers thinking that may be the problem to no avail. I'm stumped!
