Hi Nolly,
How can you mistake an avast!
anti tracker tool for a tracking device is beyond me. This very part of the avast solution disables third party tracking in your firefox browser, so it does not track itself but blocks others from tracking you. If users read the word" tracking" somewhere without really understanding the workings of the tool, they immediately get paranoid and into arms. It always is a bad thing to get paranoid without understanding why. This part of avast av is just disabling and blocking third party tracking. In your case it is just something you should want and be glad to have. Do you want to be tracked?.
When the answer is no, then do not disable it. The number is just the amount of tracking being blocked!
