Youtube complains of a lack of local storage? Try this...

It seems youtube would really like you to (aka forces you to) enable enable flash storage for third parties and enable at least 10 kg storage for everybody by default. This is most certainly not a technical necessity, but to make advertizing work better. Otherwise you can't save your youtube 3d settings. But once you've saved your 3d settings, you can switch third party storage back off. ;)
