AdBlock Not Downloading

Constantly receiving an error message when I attempt to download AdBlock on Mozilla Firefox. Message reads: "The add-on cannot be downloaded because of a connection failure on" However, downloading works on Google Chrome. I paid for this. Why doesn't it work?

AdBlock Plus worked perfectly before and it is free. Now I receive the same error message from that program as well on Firefox.

    This is strange. I'll check with our team why this might be happening and I'll get back to you.

    Hi Sande,

    This is a known issue with Firefox. Often if you keep trying, it will spontaneously fix itself. Otherwise, there are a couple of workarounds, one of which should work for you.

    First, are you using an antivirus program such as Avast? If so, please disable it temporarily and try installing AdBlock again from

    If disabling your antivirus doesn't work or you don't have one (insert standard antivirus lecture here :), please try downloading the extension and opening it directly in Firefox. I found a pretty nice video on YouTube that walks you through how to do this. It also provides a third workaround if the first two don't work.

    Please let us know how it goes!
