Firefox 3.6.3: Disable third party cookies

Woo! New version of Firefox came with Ubuntu 10.4!

I couldn’t immediately figure out how to opt out of receiving third-party cookies, but got there in the end. Here’s where the tickbox is hidden….

Navigate to Edit -> Preferences and select the Privacy tab.

Under the ‘History’ heading, there is a line that starts “Firefox will:” and a drop-down menu. Select “Use custom settings for history” from the drop-down menu.

This will cause some new options to appear, including “Accept third party cookies”. Untick this box and click “Close”.
