Check these settings Please.
Tools-> Options-> Privacy section-> Private Data-> Is there a check mark in 'Clear Private Data when I close the browser'?
Now if check mark is there then remove that mark & your problem is solved!

I had the same problem. I posted the same question in another forum and received an answer that solved the issue. I deleted the prefs.js file. I had to "rebuild" my preferences but it solved the cookie issue.
Try to delete cookies.sqlite (and cookies.txt) in the Profile Folder (http://kb.mozillazine.org/Profile_folder_-_Firefox)
