XMLHttpRequest Security errors

Hey /prog/, not a regular but I thought I'd try you guys - I'm running into problems when I try to load cross-board content using xmlhttprequest. Apparently it only works in the same domain, so I get security errors when a link pointing to img wants to load content from dat (the cross-board links send you to a redirecting page which does this). Any ideas on how to work through this? I'm running the code through the Greasemonkey Firefox extension. Thanks!

...Do you even know how the internet works? Anyone who is using a plaintext password input is going to be insecure anyway. And the fuck anyway- for your scenario to happen the user needs to run a malicious script on that page; or the server needs to have been compromised in which case whether or not they are using AJAX to remotely deliver posted passwords has no effect whatsoever on the insecurity.
