We support adding xpinstall permissions via the xpinstall.whitelist.add.* and xpinstall.blacklist.add.* preferences, however there's no way to remove a permission from the database. We should support the following prefs to do that: - xpinstall.whitelist.remove.* - xpinstall.blacklist.remove.* Of course, there's some issue with removing permissions that have been manually set by people - so they'd have to be used cautiously. But it would be the more correct way to remove a site that was once automatically given a permission, that we want to remove (such as bug 861101).
