+ * Bug 1714354 - Fix for site issues with web APIs in private browsing
+ *
+ * Some sites expect specific DOM APIs to work in specific ways, which
+ * is not always true, such as in private browsing mode. We work around
+ * related breakage by undefining those APIs entirely in private
+ * browsing mode for those sites.
