Firefox 81.0.1

Mozilla released Firefox 81 in late September, adding the capability to control audio or video playback inside Firefox by pressing the hardware control buttons on a keyboard or headset or using the Touch Bar on a MacBook Pro. The Web browser also introduced the colorful Alpenglow theme for both Light and Dark modes; added the capability for users in the US and Canada to save, manage, and auto-fill credit card information; and introduced AcroForm support for filling in, printing, and saving supported PDF forms.

Mozilla released Firefox 81.0.1 in October to fix missing content in Blackboard course listings, resolve incorrect scaling of Flash content on HiDPI macOS systems, and fix a bug that caused Picture-in-Picture controls to display on audio-only page elements.
