Another big news is the upgrade Picture in picturea feature that allows you to separate video playback from the web that now supports direct change of subtitle font size, without having to return the playback of the video to the website that supplies it. In addition, subtitles are available via Picture-in-Picture for Funimation, Dailymotion, Tubi, Hotstar and SonyLIV as of this launch.

At the interface level, new options have been added to the tab bar, whose buttons are now accessible via tab, shift+tab and cursor keys. Mozilla has published instructions and tips on how to use these new key combinations in the Firefox documentation.

For Linux the peaks are fixes performance issues with WebGL when using DMA-BUF via official and proprietary NVIDIA driver. DMA-BUF is a subsystem that provides a framework for synchronizing asynchronous hardware access and whose use is closely related to the Wayland graphics protocol. To make the problem clearer, here’s another fix for NVIDIA’s refusal to accept agreed standards for the Linux graphics stack. On the other hand, the green giant continues to refuse to officially support VA-API, the dominant framework in Linux for supporting hardware acceleration and the one used by Firefox for this purpose.

Firefox 103 is already available from the Mozilla website for Windows, Linux and macOS, although for the latter it is normal to arrive through an intermediary, which can be the distribution repository, the Snap Store or Flatpak. The Android version doesn’t seem to have hit the Play Store yet, but it should be soon. Details about this new version of the application are published in the release notes.
