I have been attempting to use Firefox Private browsing default installation out of the box on netflix, and messages.google.com/web and in netflix's case videos do not play, and google messages page is a blank white page, and also any website that uses facebook comments, that section is not loaded. What is this setting that is causing these behaviors in the private browsing mode, is there a article somewhere that explains in detail how firefox's private browsing mode works?

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Hi limava9478,

Content tracking is blocked by default in Private Browsing mode if you have ETP set to standard (see Enhanced Tracking Protection in Firefox for desktop.

To make sure if it indeed is a Tracking Protection issue, please check out the following article and let me know if it helps: How do I report a broken site in Firefox desktop?.

Could also be a problem with storage.

You can set dom.indexedDB.privateBrowsing.enabled = true on the about:config page to see if that has effect

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
