Click Disable and click "Do you want to restart Firefox now?" from INSIDE the Add-On's Tab
I was confused. Is it true then that Avast Web Shield has nothing to do with Avast Online Security?
It's true the web shield has nothing to do with the AOS...
@Jack 1000 WebRep ceased to exist with v2014 it's now the "avast online security" plug-in.
For what it's worth I completely disabled it in all of my browsers. I use PriveDog.
Ghostery has its critics...
From Wikipedia...
Criticism
Some sources say that Evidon, the company owning Ghostery, plays a dual role in the online advertising industry. Ghostery blocks sites from gathering personal information. But it does have an opt-in feature named GhostRank that can be checked to "support" them. GhostRank takes note of ads encountered and blocked, and sends that information, though anonymously, back to advertisers so they can better formulate their ads to avoid being blocked.[4]
Thus, not everyone sees Evidon's business model as conflict-free. "Evidon has a financial incentive to encourage the program's adoption and discourage alternatives like Do Not Track and cookie blocking as well as to maintain positive relationships with intrusive advertising companies", says Jonathan Mayer, a Stanford grad student and privacy advocate.[5]
Tom Simonite of Technology Review explains that with the "Ghostrank" feature enabled Ghostery sends collected user data back to the vendor, who then offers it for sale to ad firms.[5] This is also reflected in the German branch of the magazine.[6] Consequently, the German computer magazine Chip comes to the conclusion to not recommend installing the software and suggests NoScript as a (partial) alternative.[7]
According to Evidon, Ghostery does not collect any information which could be used to identify users or target ads specifically at individual users. Additionally, Ghostery would collect data only when Ghostrank is enabled. The collected data would be shared with the Better Business Bureau and offered to university students, researcher as well as journalists to support their studies.[8]
