With Firefox 146 being released today to the stable channel, Mozilla has promoted the next major version of its open-source, free, and cross-platform web browser, Firefox 147, to the beta channel for public testing.
Firefox 147 promises support for the Freedesktop.org XDG Base Directory Specification, zero-copy hardware-decoded video support on AMD GPUs to improve video playback performance, support for the Safe Browsing V5 protocol, and WebGPU support for all Apple Silicon Macs.
Firefox 147 also promises to improve the Picture-in-Picture feature by adding support to automatically open a new player window for a playing video in a tab if that tab is ever backgrounded, which was previously in Firefox Labs, as well as support for Compression Dictionaries, IETF RFC 9842.



Firefox does seem to be clearing out their old bugs (another example is MKV support) but perhaps it’s buses arriving together and not due to some policy.
