Firefox and cookie micromanagement

I used the "ask me every time" feature for many years, but had to give up because it was broken for the best part of a decade and could render your firefox unusable for several minutes while you tried to find the cookie dialog that had focus and close it (https://bugzilla.mozilla.org/show_bug.cgi?id=420155, https://bugzilla.mozilla.org/show_bug.cgi?id=515521). Given the history of those bugs I'm not surprised to see that the feature was simply dropped, rather than fixed.

I switched to the Self Destructing Cookies add-on instead, so I no longer have to care about the brokenness, or absence, of the "ask me every time" option.
