I need fine grained, automated cookie controls I have tried these addons
Cookie Manager Cookie Quick Manager Cookie AutoDelete
And the problem is always the same.
It is TOO DIFFICULT to only have one exception for one cookie in one account container
Creating containers for every single website is also extremely tedious and buggy.
And deleting all cookies all the time, means I am re-logging in into everything all the time, often a 5 to 10 step process not counting 2 factor and it is VERY annoying
It’s a slow role out, I believe it’s supposed to be available to everyone by end of may. But I do believe it can be turned on in the about:config page. Not sure what the command is though
