shortcuts and context-menu, users should take some time to initially configure NoScript as most websites depend on JavaScript and/or Java to work properly. However, in the authors’ view NoScript is only suited for advanced users as unexperienced users may not have the knowledge to configure the tool correctly and hence may be frustrated that their favourite websites do not work anymore. 5.2.3. Flashblock As the name suggests, Flashblock prohibits the display of flash-content unless the website is listed in the white-list. It activates the flash-content by clicking on it as shown in Figure 5.6. Figure 5.6.: Flashblock in action: Press the “Flash”-button to start the flash animation 5.2.4. BugMeNot With BugMeNot users can bypass compulsory web registration by using the content menu of Firefox and logging in with the data provided via www.bugmenot.com. This helps users not to provide any sensitive information to third parties by using already existing logins as demonstrated for www.nytimes.com as shown in Figure 5.7. Users can rate the success rate of logins on www.bugmenot.com and submit new logins. 48

TrackMeNot TrackMeNot tries to protect users against profiling of search engines by randomly fire off queries to search engines in the background while surfing the Internet. The tool not just generates a lot of traffic in the background, it can also be questioned if it actually works as search engines probably have ways to differ automatically from manually submitted queries. If users want to make sure that their search queries are totally anonymized, they should use an extension such as Private Web Search or a proxy as described next. 5.2.6. Private Web Search (PWS) Private Web Search (PWS) is a Firefox extension that acts as a proxy to anonymize users’ search queries. Technically seen it acts as an HTTP proxy which filters the HTTP request. It then sends the search query to the search engine via the Tor anonymity network. The HTTP Proxy receives the answer from the Tor network and then returns the results back to PWS. The result is a normal answer to a search query but no sensitive (e.g. personal identifiable) information should have been transfered to the search engine. [Sai07] describes PWS and the technical background in more detail. Unfortunately the extension could not be evaluated due to difficulties to install and setup PWS. 49
