A website can't see if private browsing is enabled.

Make sure that you do not block cookies.
You can manage all permissions on the about:permissions page via the location bar.

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
