 I see increasingly XSS warning popups showing up because of timeouts which
 is highly confusing. Clearly, timeouts are not really an indication of an
 XSS issue. An example for how this looks like is:
 {{{

 from https://www.zeit.de to https://dx6ctphzljkf1.cloudfront.net.

 Suspicious data:

 That does not involve doing anything special just reading news with an
 9.0a6-ish Tor Browser.
