Safari for Snow Leopard failing to block cookies

updated 10:45 am EDT, Mon August 1, 2011

Issue linked to Mac OS X 10.6.8

The Snow Leopard version of Safari is failing to block cookies properly, says security firm Sophos. Users running the browser on Mac OS X 10.6.8 in particular are reportedly seeing the software continue to keep some cookies active, even when settings have been changed to block all of them. Even the Safari 5.1 update hasn't solved the problem, according to Sophos.

The issue appears to be connected to Snow Leopard rather than Safari, since Safari 5.0.5 on Mac OS X 10.6.7 manages cookies as intended. Sophos adds that there appears to be no obvious reason why some cookies are tracked in v10.6.8 and not others. The firm notes that during testing, it encountered an assortment of session, short-term and long-term cookies.

Tracking is also managed correctly in OS X Lion, which comes with Safari 5.1. Apple has not commented publicly on the topic, even on its support forums. It's therefore unknown if or when Apple will issue a patch, although the company will likely make it a Security Update for Snow Leopard rather than a v10.6.9 distribution.

    This is yet another example of the problem with the browser frameworks being part of the OS. An OS update should not break a piece of browser functionality.

    And because of this, you'll probably find out that any other browser using the WebKit frameworks will have the same problem.

    Cookies reappear after deleting

    Not sure if this is a bug in the cookie deletion code or just the cookie display code. But open Safari 5.1's prefs, click the Privacy tab, then click the "Details..." button. Search for something, then hit delete after highlighting one of the rows in the search results. Once in a while, that row will re-appear.
