Firefox setting to enable cross domain Ajax request

Question

I need to temporally allow cross domain XMLHttpRequest. Changing firefox security setting seems to be the way to go. But I\'ve tried with this and this but they did

Answer 1

To allow cross domain:

1. enter about:config
2. accept to be careful
3. enter security.fileuri.strict_origin_policy in the search bar
4. change to false

You can now close the tab. Normally you can now make cross domain request with this config.
