Browser.download.manager.skipWinSecurityPolicyChecks

Background

Starting with Firefox 3, the Windows security settings for downloading applications and other potentially unsafe files from the Internet are honored on files downloaded by the Download Manager. This allows, for instance, system administrators to block executable files from being downloaded by Firefox. This preference allows Firefox to ignore those OS-wide security checks.

Possible values and their effects

True

Do not use Windows’ IAttachmentExecute interface when downloading files, ignoring the security settings for downloads.

False

Use IAttachmentExecute when available (Windows XP SP1 and newer). (Default)
