Comment(by pde):

 Matt Perry sent this by email:

 > OK, upon further investigation, it is not related to the fact that this
 is a POST request. It's actually caused by a conflation of 2
 implementation details in Chrome:
  1. The translate request is done using a XMLHttpRequest from the context
 of the main page. In this case, the translated page is requesting
 http://translate.googleapis.com/...
  1. The webRequest API rewrites URLs by simulating a redirect. When HTTPS
 Everywhere tells us to redirect !http://foo to !https://foo, we actually
 simulate a redirect internally.

 > Because of (1), the redirection in (2) is considered cross-origin (the
 security origin is that of the main page, and the redirected URL's origin
 is translate.googleapis.com). Chrome (specifically, !WebKit) blocks this
 cross-origin redirect.
 >
 > I could be misunderstanding web security policy, but it seems like a bug
 to me. I don't see why redirecting an XMLHttpRequest from
 !http://translate.googleapis.com to !https://translate.googleapis.com
 should care about the security origin of the containing page.
 >
 > In any case, it's a Chrome issue. I think your only workaround is to
 exempt translate.googleapis.com from the rules.
