Mozilla Releases Firefox 100

Mozilla today announced the release of Firefox 100 for Windows, Mac, and Linux, adding new subtitles and captions features for Picture-in-Picture (PiP).

“Beginning with Firefox 1.0, we’ve continued to put our users first to develop and deliver on the features most important to them,” the Firefox team explains. “Our mission then—to build an internet open and accessible to all—still remains the same today. That’s why, nearly 99 releases later, we’re excited to introduce subtitles and captions to Firefox’s Picture-in-Picture (PiP).”

Mozilla added the PiP feature to Firefox in 2019, letting users pop video playback out from the main browser window and into a standalone player. It later added Multiple Picture-in-Picture (multi-PiP) for multiple pop-out video players. And now it is adding support for subtitles and captions in Firefox’s PiP windows.

“The subtitles and captions feature in Picture-in-Picture is available on three major streaming sites—YouTube, Prime Video, and Netflix—plus all websites that support the emerging W3C standard called WebVTT (Web Video Text Track) format, such as Twitter and Coursera,” the firm explains. “It’s really as simple as turning on the subtitles or captions on the in-page video player of your favorite website, and they will appear in PiP when launched.”

You can download Firefox from the Mozilla website.
