User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0) Gecko/20100101 Firefox/4.0

I used an empty new profile to test this in FF4.

1. I set the preferences to: Use custom settings for history -> Accept cookies from sites -> Keep until they expire

2. Went to a site that sets a cookie that, after logging out will expire in 30 minutes.

3. Quit FF

4. Opened FF one hour later, cookie still there

5. Quit FF

6. Opened FF again and cookie is still there


I performed the same test in FF3.6.13 and the cookie is removed.

Reproducible: Always

Actual Results:  
Out of date cookies in FF4 are not removed

Expected Results:  
Out of date cookies should be removed when FF is quit

Using FF4 on OSX 10.6.6

Expired cookies are not continuously removed from the database (that would cause many write operations, spinning up the hard disk on an idle laptop for instance). They're not even removed when the application starts up (that was removed in bug 576347 to speed up startup). When the cookie is found during a read operation, it will not be used of course.

There is a PurgeCookies routines at <http://mxr.mozilla.org/mozilla-central/source/netwerk/cookie/nsCookieService.cpp#2729>, but it will only clean the database once in a while (10% over the size limit). Bug 576347 is an attempt to have a smarter routine that might run once per day when the browser is idle or something.
