Mozilla has wiped 23 extensions from its directory of Firefox browser add-ons after finding what it says were inappropriate functions in the code.
The incident follows a report last week that German security add-on ‘Web Security’ had been misbehaving. Mozilla had highlighted the add-on in a blog post promoting a collection of security-focused extensions to the browser. That prompted eagle-eyed techies to pick apart the program and find out exactly what it was doing. They discovered it assigning each user an ID and sending information labelled ‘old-URL’ and ‘new-URL’ to a consistent IP address.
