Mozilla, of course, states that this feature will ensure that any content which attempts to profile the user will be automatically blocked from things like analytics, social media, and other services that might collect data without you knowing about it. However, Firefox new Private Browsing feature actively blocks various components of the websites that could track your behavior.

New Experimental Private Browsing and Add-ons Features Ready for Pre-Beta Testing in Firefox [Mozilla, via Liliputing].

Compatibility Mode is still present and correct in Windows 10, so you can try that too: right-click on an executable, choose Properties and open the Compatibility tab. As per details from the latest pre-BETA build, Firefox will be disconnecting you from the services that are used for tracking, which in some cases causes the breaking of the website. The stealth new mode will essentially test the enhancements which Mozilla has made to private browsing in the Firefox browser.

Separate plug-ins have been obtainable prior to now to do exactly that, however now Firefox combines the power in its personal private browsing mode. Your internet provider – and potentially your IT department, if you’re browsing from a work computer or through a VPN your company provides – will be able to see where you go, what you look at, and which files you download.

Mozilla CEO Chris Beard has blasted Microsoft in a pair of posts to the organization’s blog, arguing that Windows 10’s default browser settings are a “dramatic step backwards” for respecting user choice.

Mozilla also mentioned that websites that use a lot of data may not load correctly, but the feature will allow the user to unblock certain websites if they want leaving control in the hands of users.

These enhancements are available in the Firefox Developer Edition for Windows, Mac, Linux, and Firefox Aurora on Android.

Mozilla also announced a process to verify that installed Firefox add-ons satisfy safety guidelines and criteria.
