If you are using Firefox, you can disable referrer info without using a plugin. Here‘s how: In the URL bar, type the following and press enter: about:config Now search for the following entry on the page: network.http.sendRefererHeader The default value is 2. Change this to 0. This disables the referrer header. Note that some sites won‘t allow you to sign in or register if the referrer header is disabled (e.g. Pinterest), so you may have to temporarily enable the referrer header in those instances. A final point is that this Firefox setting obviously has no effect if referral info is already appended to the URL (as is the case with Google search results).
