Can I disable SOP (Same Origin Policy) on any browser for development?

javascript soap wsdl same-origin-policy

I want to develop JavaScript on my Windows machine. Do you know a browser where I can turn off Same Origin Policy so I can develop locally? Firefox would be optimal.

Or if you know a proxy I could use for a SOAP/WSDL site it would be great too.

I am trying to work with the JavaSCript SOAP Client.

UPDATE 6/2012: This used to work at the time of the writing, but obviously no more. Sorry.

In Firefox (might apply to other Gecko-based browsers as well) you can use the following JavaScript snippet to allow cross-domain calls:

if (navigator.userAgent.indexOf("Firefox") != -1) {
    try {
        netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
    } 
    catch (e) {
        alert("Permission UniversalBrowserRead denied -- not running Mozilla?");
    }
}

It looks like there's an issue created in the Chromium issue tracker for achieving the same functionality, so you could try starting Chrome with the argument --disable-web-security. I don't know which builds this works on exactly, but at least Nokia's WRT Tools comes with a Chrome installation that does in fact allow loading content from other sites.
