I need to make a cross domain request from a script that runs in firefox (it's just for development purposes).
Can this be achieved? maybe modifying the about:config keys?
Thanks!

CORS or Cross Origin Resource Sharing is blocked in modern browsers by default (in JavaScript APIs). Installing this add-on will allow you to unblock this feature. Please note that, when the add-on is added to your browser, it is in-active by default (toolbar icon is grey C letter).
In Firefox, the preference that disables CORS is content. cors. disable . Setting this to true disables CORS, so whenever that's the case, CORS requests will always fail with this error.
Open a network tab in your console. In the response header look for the Access-Control-Allow-Origin header. If it does not exist then add it as a middleware in the way we discussed above. If it does exist then make sure there is no URL mismatch with the website.
There is a great post by James Padolsey on how to to cross domain requests using jQuery, But the post also has very good resources. There need to be some tweaking to be done on the other server to allow cross domain calls using crossdomain.xml
