Another new feature is HTTPS-Only Mode. This is an optional feature that can be turned on in Firefox Preferences. As you can see from the name, this mode will ensure that all of your connections to websites are encrypted and secure giving you peace of mind when connected to a public network. If a website does not support HTTPS, you will be greeted by a ‘Secure Connection Not Available’ message. You do have the option to proceed to the website using only HTTP but the warning will let you know before you proceed.
Some other notable changes include pinch zoom support for Windows touch screen devices and touchpads on Mac devices, the directional arrows can be used to fast forward, rewind and adjust the volume in Picture-in-Picture mode, and AcroForm support has been added which lets you fill in, print, and save supported PDF forms.
The firm said that this release is big for WebRender as the rollout expands on Windows 7 and 8 as well as on macOS 10.12 to 10.15. Regarding Mac devices, the firm said that Firefox 83 and above will work on Apple’s new Silicon CPU using emulation under Apple’s Rosetta 2 that ships with Big Sur. Going forward, the firm will support the new processor natively.
