 I am trying to use the website [http://lang-8.com Lang-8] (a social
 networking site for language learning) with tor browser. I can create an
 account but I cannot log in. Whenever I enter my user name and password on
 the lang-8 login page, I am redirected back to the welcome page of the
 site and I do not appear to be logged in.

 I do not get any kind of error message, so I don't think that the site is
 deliberately blocking tor.

 I have tried both Tor Browser version 3.6.6 and 4.0-alpha-3; the problem
 occurs with both versions.

 First I thought that maybe https-everywhere is to blame, but disabling it
 does not solve the problem.

 After some experimentation, I discovered that if I disable the NoScript
 extension in Tor Browser (via the Addons menu item in Firefox), I can log
 in to lang-8 successfully. So it seems that NoScript is causing the

 Of course, turning off NoScript is not a viable long-term solution. I
 tried turning on NoScript again, but adding a regexp matching lang-8 urls
 to the NoScript XSS protection whitelist, but this didn't help.
