Bug in WebRep in Firefox

I noticed yesterday that the window of WebRep in Firefox does not mention the website’s name and marks all the websites as top-rated by me. This problem exists in two computers running Windows XP and Windows 7 respectively and I suspect that it appeared after the update to the latest version of avast. WebRep is running perfectly in Internet Explorer.
See the screenshot. I am sure that I have not voted for the site mozilla.org
Thank you.

Can anyone confirm the problem or is it just me?

It isn’t just you, but I rarely open the WebRep interface when I have a page displayed, perhaps more in the search rather than after the fact.

Another issue is that the Vote button is there and I have obviously voted for avast.com, so there doesn’t appear to be any linkage between the site and if the users has voted.

I don’t know if that has anything to do with the site name not being displayed or not.
