Definitely, please make this happen, with the change that it should be per page not per session I think.
For example, I may look at a huge pdf,
and then browse to a URL within afore mentioned pdf from the same session.
If js is auto-disabled by the pdf for that session then it would stay disabled
for the web page which is probably not what I want,
whereas if the check is done per page then it'd re-enable itself when I change page.

Cheers,
Adam.
