Released earlier this week, the Firefox 74 web browser introduces a new sandboxing technology for Linux systems to keep users safer than before when surfing the Web, rolls out DNS over HTTPS by default for users in the US, and deprecates the TLS 1.0 and TLS 1.1 cryptographic protocols. Other changes in the Firefox 74 release include support for site exceptions in the Facebook Container, more secure web voice and video calls, reverse name sorting in the Lockwise password manager, and improved uploading of videos with multiple images on Instagram.
