Thomas, thanks for explanation. However please consider several possible cases today and for this wish.

Case -- "dumb" people. Can they today load external sources? Yes. So where is security issue? If you split option into two there is no security improvement (for such case) nor regression.

Case -- total security. Can they block external sources? Yes. Will they block ext. sources? Yes. No change in security.

Case -- balanced security (on purpose). Impossible to do today. With this wish I would be able to do this, without sacrifying completely readability and security.

I see no regression here, but for some users improvement actually.

> It was designed to block everything which loads from an external server,

It would be still possible to do, there is no change.

Unrelated question, but I am curious -- how it is possibl, I mean how long I read mail? Server sends gif file and...? (note: consider only "static" data)
