EFF has just announced a new privacy protecting plugin for Firefox and Chrome.
What is Privacy Badger?
Privacy Badger is a browser add-on that stops advertisers and other third-party trackers from secretly tracking where you go and what pages you look at on the web. If an advertiser seems to be tracking you across multiple websites without your permission, Privacy Badger automatically blocks that advertiser from loading any more content in your browser. To the advertiser, it's like you suddenly disappeared.

Data Broker Limited, from Cheshire, caters to predatory lenders — "[if you're] offering new loans to people With poor credit history and [county court Judgements against them], Databroker have the largest list related to loans for postal, telephone, mobile, SMS, email and social media campaigns".

Seems worthwhile to at least try to reduce how much your learners', teachers', and admins' personal information and browsing habits are exposed to such dubious practices.
