Logging into Usermin as a user from Webmin Fails in Firefox 18 beta, which implements X-Frame-Options.
When clicking from Webmin 1.610 into Users and Groups, then clicking a User and choosing "Login to Usermin" at the bottom, the right-hand frame displays a blank page in Firefox 18 beta.
Looking at the Console in Firebug:
"Load denied by X-Frame-Options: https://mysite.com:21001/ does not permit cross-origin framing."
The Webmin site is located at https://mysite.com:10666/ which is not the same Origin as the Usermin site because it's on a different Port number.
I noticed in the Webmin source that this seems to be set here at line 749:
(I believe the Usermin source references the same file)
print "X-Frame-Options: SAMEORIGIN\n";
Could this be set to the Url of the Webmin server, either somewhere in the settings of Usermin, or automagically?
print "X-Frame-Options: ALLOW-FROM WEBMINURI\n";
