Fix Firefox 4 beta not displaying images on certain sites.

I’ve switched for a while to FF4 beta and i’ve noticed that on certain sites the images don’t load properly. They ofcourse load just fine on other browsers (chrome, opera).

Turns out it’s a FF4 setting and here’s how to fix it:

1. Type “about:config” in the location bar, and press ENTER.
2. In the filter box, type “referer” and press ENTER. This should
leave you with one preference, “network.http.sendRefererHeader”. This
is probably set to 0.
3. Right click on network.http.sendRefererHeader and select “Modify”.
4. In the dialog that appears type “2″ and press OK.
5. Restart your browser.
