5.1.2. Firefox<br />
The Mozilla Foundation had built in P3P support in its software. But after a long<br />
discussion it was eventually removed completely from its browser-line and so neither<br />
SeaMonkey nor Firefox have built in P3P support anymore [Moz07]. One of the reasons<br />
for the removal was that the code “has not been owned or touched since 2003” [Moz07].<br />
Michael Kaply from IBM even stated: “Ah the memories. We (IBM) wrote the original<br />
P3P implementation and then Netscape proceeded to write their own. So both our companies<br />
wasted immense amounts of time that everyone thought was a crappy proposal to<br />
begin with. Remove it.”[Moz03]. However, Firefox 3 now by default blocks third party<br />
cookies.<br />
5.1.3. Safari<br />
Apples’ Safari for Windows does not offer any privacy settings whatsoever. No information<br />
is displayed when third-party cookies are blocked, no privacy report is shown or<br />
could be accessed. The only option users can set is a radio-box whether they want to<br />
accept third-party cookies or not as shown in Figure 5.4.<br />
5.1.4. Opera<br />

cookies (cp. Figure 5.5). Blocked cookies are also not shown when browsing the Internet.<br />
