You can enable or disable the referrer from being reported to web sites that you visit with this Firefox tweak.

1. Type about:config in the address bar and press Enter.

2. Find the entry that says Network.http.sendRefererHeader and double-click on it.

3. Set the entry to one of the following:

0 – Disable referrer.
1 – Send the Referer header when clicking on a link, and set document.referrer for the following page.
2 – Send the Referer header when clicking on a link or loading an image.

One question: Are there disadvantages to having be at “0″ – meaning “Send No Referrer”? Will it have consequences elsewhere, such as access to certain things?

Thanks!

I was just recently having problems with trying to log in to my Instagram and for some reason, when I tried the login attempt, it said there was an error and my web browser referrer head was disabled. I followed these exact steps, and it worked!
