Please correct me if I am wrong, but it seems that that STS introduces an additional site-pref like or cookie like store, that is neither viewable, editable nor clearable from NS ui. Nor, it seems, is it possible to disable STS.
So in light of the above, a couple of requests:
- Option to disable STS. It should be possible to disable any feature that allows sites to store any kind of state (cache, cookies, offline storage, history can all be individually disabled)
- UI for viewing, editing and clearing the STS store
