Bug#786565: iceweasel: breaks xul-ext-requestpolicy

[Thorsten Glaser]

Package: iceweasel
Version: 38.0.1-1
Severity: serious
Tags: security
Justification: security/privacy issue

The new version of iceweasel auto-disables the requestpolicy plugin.
To add insult to injury, it cannot be manually enabled, apparently
due to a version incompatibility.

This leads to page views no longer honouring the requestpolicy
settings but loading *all* external resources, thus violating
privacy and security, leaking user data to unwanted third parties,
disabling the probably most effective (if icky to use) ad blocker,
and cause general slowness due to ad javascript on several pages
(especially since the Intel Atom on an EeePC is so slow my Pentium M
(with less MHz) feels fast compared to it, before already).
