Comment (by eloquence):

 > What if I provide an option to just disable XSS injection checks on POST
 parameters (which would prevent the requestBody listener from being
 registered), and possibly another option to ask user confirmation for POST
 requests from JavaScript-disabled sites to TRUSTED ones, in order to
 mitigate the loss of protection?

 What will the default behavior in Tor be if, say, the user is attempting
 to upload to SecureDrop with JavaScript disabled? Would they get a scary
 confirmation dialog? It would be really good to avoid scary confirmation
 messages that make the user think that there is a security issue, when
 there really is not.

 (I realize this is now a NoScript issue again, feel free to point me to a
 corresponding issue if that's a better place to discuss. :)
