Hi, I really like Firefox and really appreciate that way that Mozilla look after my security but I cannot get my head around the fact that you have disabled one of the most useful add ons that I have ever had Ad-Block? I had ads and the way that they interfere wiith my user experience, Ad Block, as far as I can see, has done an excellent job of keeping unneccessary rubbish that I am not interested in, off my screen. This is made especially difficult as there does not appear to be a replacement tool in your recomended list. I wouyld really appreciate your assistance in solving this problem. Regards Paul Carroll
