Why do I have to click Allow All twice?

[hammiesink]

When I visit a page I know is safe, and I click "Allow All," it then seems to allow some scripts, but continue blocking others. So I have to click "Allow All" a second and sometimes third time.

Is this some new definition of the word "all" I wasn't previously aware of?

"All the scripts on this page" in this context means "All the scripts whose <SCRIPT> element is currently present in the page", and it's meant to let you allow only the scripts you can currently see reported in the menu.

Sometimes additional scripts are added dynamically by the scripts you've just allowed, and therefore you find more script sources which have not been allowed in the first "round".

The current "allow only what I can see" approach is the best for security, because this way you can't have surprise, such as finding that you've allowed a script from a malicious domain which was not shown yet when you issued the command.
