I use Firefox in the private mode because I use a public computer. This I thought would eliminate all cookies, history and passwords between sessions. But I am finding, time and again, that Gmail does not ask me for my password when I restart my browser; it automatically logs me in.

What's up with that?

How can I make sure that Google plays fair and forgets my login credentials after I close my browser?

Note: I do not check "remember me" as I login.

You can have Firefox automatically destroy your cookies and history at the end of every "browsing session", if that's what you're looking for. There are also a few add-ons that allow for the easy management of cookies on a site-by-site basis, such as CookieSafe or CookieCuller.

Yes! I thought that was done automatically. How do I configure the browser to destroy all cookies when I close it? –  picardo Aug 28 '09 at 14:40
+1 for cookie culler, excellent add-on –  jtimberman Aug 28 '09 at 14:41
@picardo Go to Tools -> Options -> Privacy, check "Clear History when Firefox Closes", and click the "Settings" button next to that, and check everything. –  MiffTheFox Aug 28 '09 at 14:46

If you go into the Firefox options and then the Privacy tab, there should be a dropdown for how long to keep cookies. By default it is set to "until they expire", you can change this to "until I close Firefox".

You may also want to check the box just below there to "Clear history when Firefox closes".
