Firefox 59 privacy

Probably the biggest change that Mozilla has made with Firefox 59 in terms of privacy that of deleting path information in HTTP referrers. Only in private browsing mode, Firefox now helps prevent data leakage to third parties, removing path information from referrers sent to third parties.

When you click on a link to navigate to a new site, the new site you visit receives the address of the site from which you came via the "referrer value". Usually this simply tells the new site the exact page you were looking at when you clicked on the link. But the content embedded in the new site can also get this information, which can be collected and sold to the highest bidder. Sometimes referrers include the information you entered on the previous site, which can be quite problematic, depending on what you were doing before clicking. The Firefox browsing mode removes the domain name information from the previous site. Speaking of privacy, Firefox 59 adds a new setting in Preferences to prevent websites from asking to send notifications or access the camera, microphone or location of the device. You can allow trusted websites to use these features even if you deactivate them for the rest of the Web.
