Really strange, there's nothing at line 1347 which could trigger this error unless it is caused by something JS wrapping the channel.
Does it happen also on a clean profile with just NoScript installed?
If not, please use Standard Diagnostic to find the very likely interfering extension.

For me it is happening while trying to install any userscript from http://www.userscript.org while Greasemonkey is installed.
No idea which addon is at fault here as the error only pops up when both addons are active.
Confirmed with a new profile and only those two addons installed, no allowing of any sites needed.
