Suggested title: "How do Websites Track Me?" and would fit quite well after the "What Are Cookies?" section which provides the background on primary and 3rd-party cookies. There is a review on the Collusion add-on by greylanternlight who kindly gave a list of privacy add-ons: Better Privacy, NoScript, Ghostery, AdBlockPlus, Request Policy and Privacy Choice. I don't think though that specific add-on names should be listed in the general help, rather a generic hint to search for add-ons in the Privacy & Security section (which returns a rather long list, though).

This patch adds a new section "Why and How Are Websites Tracking Me?" with a general discussion on tracking pros and cons, then followed by a section on the mechanisms of user tracking, followed by a section on how to prevent it. I've got the information from the sources mentioned in bug 631566 comment #10 and from the general discussion on fingerprinting in bug 572650, along with a bit of common sense (or so I hope). This patch also links up "Tracking" in privsec_help.xhtml with this new section, and "malware" with glossary.xhtml (yet to come with bug 847182). Everything else in this file a white-space changes caused by rewrapping the respective paragraphs.

Comment on attachment 720514 [details] [diff] [review] Proposed patch Minor issue found: >+ <li><a href="using_priv_help.xhtml#cookies">Cookies</a>: The power of >+ tracking cookies is their persistence across sessions. Thus, when you >+ restart &brandShortName;, the identifying cookie will still be sent to >+ the website performing the analytics. One measure against third-party >+ tracking is to prohibit third-party cookies altogether; another option >+ is the restriction of cookies to the current session only. Some websites >+ may no longer function correctly, but you can add exceptions to such sites >+ in the Data Manager or with the Cookie Manager from the Tools menu.</li> The reference to the "Cookie Manager" at the end is wrong as we do no longer have a separate Cookie Manager (despite the menu item still being named as such) but it's part of the Data Manager now. I've change the end of the paragraph locally to >+ the Data Manager or with the Cookie Manager options in the Tools menu.</li> and will add that change to the next patch unless you want it differently. The entire Cookie Manager/Data Manager thing should be cleaned up in bug 599097, a respective note is already on top of this list item to revisit it later.

Since Stefan wants to have further references from other parts of the help text to the glossary, I'm going to move the "malware" part to bug 847182 which is a better place, rather than as a drive-by fix here. The "Tracking" link remains. (In reply to rsx11m from comment #3) >+ the Data Manager or with the Cookie Manager options in the Tools menu.</li> Done.

Thus, if you need such plugins for This doesn't sound right either, perhaps "Obscure plugins make browser finger printing easier"? r=me with those addressed.

Thanks Ian, comment #5 addressed.

Push for trunk, please.
