Why Does Chrome Keep Session Cookies After Closing, Unlike Other Browsers?

Chrome's Unusual Approach to Session Cookie Persistence

Question:

Why does Chrome retain session cookies even after browser closure, unlike Firefox and Opera?

Answer:

Chrome's behavior is likely influenced by its default setting, "Continue where you left off." This option maintains open tabs and website states across sessions.

Further Analysis:

• Session cookies typically expire when the browser is closed, erasing temporary data.
• Chrome's exemption of session cookies from expiration in Mac OSX Lion, but not in Windows XP or Ubuntu, suggests OS-specific variations.
• To address the issue, check if "Continue where you left off" is enabled in Chrome's settings. If so, disable the option to restore the expected session cookie expiration behavior.
