New: Firefox now supports touchpad hold gestures on Linux. This means that kinetic (momentum) scrolling can now be interrupted by placing two fingers on the touchpad. HEVC hardware support is implemented for Windows users. Fixed: Fixed an issue that started with macOS Sonoma where the emoji picker would open and immediately close when opened with the Cmd+Ctrl+Space shortcut. Thanks to research by Carlos Duarte do Nascimento (Chester) and :bintoro, and a patch by Carlos Duarte do Nascimento (Chester), we have been able to fix this universally for this shortcut and similar shortcuts going forward. Fixed an issue that started with macOS Sonoma where the emoji picker would also insert the character "e" in the selected text field/box when opening the emoji picker using the Fn+e shortcut. We have also fixed this for similar shortcuts using the Fn key. Changed: Firefox follows now the model HTML specification for transient user activation more closely. This change makes popup blocking less strict in cases where previous versions of Firefox were overly aggressive, reducing erroneous blocking prompts. |

New: Microsoft PlayReady encrypted media playback is now being rolled out to select sites on Windows. Through this support, we are gradually rolling out a 1080p baseline and 4K Ultra HD support with key streaming partners. An added benefit is that viewers get less battery drain and better performance when streaming their favorite movies and shows. Wide Color Gamut WebGL is now available for Windows and macOS users! With this support, Firefox is bringing a richer, more vivid range of colors to the videos, games, and images on your screen. This implementation currently supports wider color (P3) profiles in 8-bit. WebRender hardware accelerated rendering is now enabled for most SVG filter primitives, improving performance for certain graphics-heavy content. Accelerated filters are feBlend, feColorMatrix, feComponentTransfer, feComposite, feDropShadow, feFlood, feGaussianBlur, feMerge and feOffset. Added support for macOS’ new screen and window sharing selection features on macOS 15 and later. Support for macOS 14 will be added in a future release. The macOS session resume feature has been enhanced. Firefox will now automatically relaunch if it was open before a system restart, like after an OS update. Firefox now blocks third-party cookie access when Enhanced Tracking Protection's Strict mode is enabled.
