GRC visitor cookie configuration by browser

Notes

"FP Persist" — First-party Persistent cookies. For additional information about the meaning of these cookie types, please see the Tracking Terminology page. "TP Session" — Third-party Session cookies. "TP Persist" — Third-party Persistent cookies.   "FP Session" (first-party session) cookies are not separately displayed in the tables and charts above because first-party session cookies are required to prevent multiple counting of visitors, therefore, they would always be "100%". To guarantee the reliability of this data, users who block all cookies are not represented here because there is no way to reliably count them without any cookies. But since our primary goal is to encourage third-party cookies to be disabled, while allowing first-party cookies — especially first-party session cookies — and since all browsers enable first party session cookies by default, this approach allows us to accurately display the percentages of third-party cookie disabling among all Internet browsers.   The "Gecko" browser category includes any Mozilla-based browsers other than Firefox v2 & v3. These are primarily Linux and Unix users who, as can be seen from the statistics above, are more security and privacy aware than the average user. Therefore, these people have disabled cookies more than any other population using browsers with third-party cookies enabled by default.   The "Other" browser category includes any cookie-supporting web clients such as 'bots' or other user-driven or automated agents that do not identify themselves as one of the other well known web browsers. High-visibility bots & spiders, such as those belonging to Google, are recognized and never offered cookies, so their influence will not appear here.   The chart above clearly demonstrates the importance of a browser's default settings. Apple's Safari web browser is the only web browser that disables third-party cookies by default and protects its users from third-party Internet tracking.
