javascript - Share credentials with cross domain script tag in Firefox -

suppose i've authorized in domain boo.com , have session:

s:x2gyrvxggmsffwx7gdbkxmwb.4bdxlpmasqd9hgetkbdx3z4teczjec50gnrh5bc+kwu 

what want add script tag domain foo.com, points boo.com:

<script src='http://boo.com/blah.js'></script> 

in browsers including safari , google chrome, script tag sets cookie value in http headers doesn't work in firefox.

firefox doesn't set cookie headers unauthorized error server. problem?

update:

i enabled cors in server-side problem still exist in firefox:

app.use(function (req, res, next) {   // website wish allow connect   res.setheader('access-control-allow-origin', 'http://foo.com');    // request methods wish allow   res.setheader('access-control-allow-methods', 'get, post, options, put, patch, delete');    // request headers wish allow   res.setheader('access-control-allow-headers', 'cookie');    // set true if need website include cookies in requests sent   // api (e.g. in case use sessions)   res.setheader('access-control-allow-credentials', true);    // pass next layer of middleware   next(); }); 

here solution:

<script src="http://boo.com/blah.js" crossorigin="anonymous"></script>
