Blocking cookies from sites settings aren't retained next session
I added some 20-25 repeat offender tracking sites to my Cookies and Site Data/Exceptions... block list, only to find when I rebooted my machine and relaunched Firefox that not one of these sites had been kept, ie there are no exceptions to the general setting of accepting cookies now.
I want to block these domains always and forever, full stop. Dutifully adding them to the blocked list and saving the changes doesn't appear to last longer than my current Firefox session. How do I permanently block them without having to manually enter them every time I reboot?
