ALLOWED Cookies Exception List does not retain entries from session to session.

YES, I've searched the KB for an answer...no joy. I want to manage my cookies by adding the few sites that I want to allow cookies for, with all other sites being denied, and me being prompted every time a site wants to dnld a cookie. I believe I understand all the available settings, but I can't bet FF to retain the list of allowed sites from session to session, and sometimes FF won't retain them even immediately after I save them. I never had a problem with FF3, but now I'm having this problem with FF4.

You can't keep cookies if you run Firefox in Private Browsing mode.
In Private Browsing - Use Firefox without saving history mode all cookies are session cookies that expire if that session is ended, so websites won't remember you.

Make sure that you do not use Delete browsing, search and download history on Firefox to clear the "Cookies" and the "Site Preferences"

Clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, and passwords.

Issue unsolved. Hoping to receive deeper analysis.

Thank you cor-el, that's a good suggestion, but, something I already knew. I didn't execute Clear Recent History...Clear Recent History is NOT the cause of the problem.

Additional Information: In Options\Privacy\History my settings are: "Use custom settings for history", Permanent Private Browsing mode = ON, Accept cookies from sites = OFF. Should I expect to be able to click on the Exceptions button, and enter urls into the exceptions pop up window as ALLOW, and expect them to be there in subsequent FF sessions? I've noticed that the Exceptions pop up window does not have an "OK" button as I would expect from observed FF convention...should there be one? After entering a url, my only choice is a "Close" button or the Red "X".

Follow on question: Is it possible that a data error occurred during install, preventing an applet from loading correctly, which would prevent the retention of list entries into the permissions.sqlite file? My permissions.sqlite file is located where the KB says it should be, shows a size of 2K, and a Date Modified of today. Note: I have continued to try to enter and save urls into the Exceptions List with an ALLOW value with no success.

Or, perhaps I should migrate back to FF 3.xx?

Thank you cor-el.

Hmmm, I wonder if the dev team would want to see this string and consider editing the KB to reflect or emphasize that even though the user is able to enter and save url's in the Exception list while having Private Browsing selected, those entries are moot? Or, perhaps it would be an advantage to disable the Exception button when Private Browsing is checked? Is there a way to submit these suggestions to the dev team?

Again, thanks for your help!  :+>

This question actually talks about the list of URLs in the cookies exception list not with the cookies themselves. As with FF3.6.X and earlier, you could have unticked the 'Accept cookies from sites' option while in private browsing mode and have a list of websites that you DO want to allow cookies in the Exceptions list. However in FF4.0 this exceptions list of URLs is cleared, so when you reload FF the cookies exception list is empty.
