Hello,
WebRep is not working with FF 6
Regards
Relu
FF has disabled it because WebRep isn’t compatible at this time.
I am sure Avast will fix the issue, personally myself I do not use it.
27 September will be a Firefox 7 - we again have to wait a month for compatibility with WebRep?
No. 
Good news! Thx! 
You’re welcome…!
