Mozilla’s Firefox browser has had a security update that beefs up the Private Window viewing option. Or does it?

Lance Cottrell, chief scientist for Passages at Ntrepid thinks otherwise.

“Firefox’s new ‘Private Browsing with Tracking Protection’ provides significantly improved privacy, but is still far from comprehensive. Users are still vulnerable to tracking through browser fingerprinting, IP addresses, malware, and other advanced techniques. Providing privacy and security by blocking ads and third party content is a short term fix,” he said.

“We are already seeing websites deploying ad-blocker-blockers where websites deny access to users with active ad blockers. As long as the fight stays within conventional browsers, this will continue to be a cat and mouse fight with no clear path to victory,” he added.
