Hello Why is dealing with container is so hard? I mean it's like peoples who design it don't use it, there is a lot of design flaw in it (like when it ask wich container to use but you can't select no container so firefox will purposelessly force you to be tracked by Google or Facebook, it make no sense at all). And more globally, firefox brag to be about privacy, but for the end user like me there is to much design error to make it easy to use (we can't make inactive an extension from the browser, we always have to go to these menus it's really boring and in the end you stop using privacy module because of this) I think Firefox should not be about privacy on paper only but really designed to be practical about privacy and I think it's not going good and most peoples will end to don't care about privacy because of this (and switch to chrome or else). Oh and I will be pleased to help and give more detailed informations about all those design problems, and how they occur, to fix them and improve Fx. But I won't continue to use Fx is the main reason to use it now : the privacy settings, are not easily usable in everyday's life. Regards
