6.2.2. Functionality<br />
Besides compatibility issues with Firefox and the P3P standard, there are also some<br />
issues which have to be addressed regarding the functionalities of Privacyfox:<br />
• Privacyfox can only check for P3P policies if the domain name does not contain<br />
any hyphens (e.g. the hostname “www2-ibm.com” cannot be checked).<br />
• There is no support whatsoever for setting user-specific preferences.<br />
• Hence, no actual check can be made whether the currently visited website actually<br />
matches the users’ privacy preferences.<br />
• Furthermore, no visualization is available which indicates users the current P3P<br />
status of the website (e.g. if it matches or does not match the users’ preferences,<br />
if the website has a P3P policy at all, if the policy is well formed or not etc.).<br />
• The option to display the P3P policy is hidden in the “View”-menu of Firefox.<br />
When clicking the corresponding menu entry (cp. Figure 6.1), Privacyfox simply<br />
opens a new tab and displays the parsed P3P policy as shown in Figure 6.2.<br />
