See what landed recently in Firefox Nightly!

Starting with Firefox 145, macOS Nightly users will, by default, have a dedicated GPU process. This includes WebGPU, WebGL, and Firefox's own WebRender. With this feature enabled, fatal errors in graphics code will no longer crash the browser, and will instead transparently restart the GPU process. This feature can be disabled by the pref layers.gpu-process.enabled.

When a website uses a file upload field (<input type=file>) without specifying what types of files it accepts, Firefox for Android will now offer additional options to make file uploads easier. Users will see choices to pick a file, take a photo, or record audio directly from their device.

For users of the English-language versions of Firefox in France, Germany, and Italy, the address bar will now show English-language suggestions for holidays and other important dates.

Starting with Firefox 145, Nightly builds now support Storage-Access-Headers allowing servers to opt-in into un-partitioned cookies via HTTP headers if storage-access was granted prior with the Storage-Access-API.

Starting with Firefox 144, layer compositor is enabled for WebRender on Windows in Firefox Nightly.

Starting with Firefox 145, the text-autospace property is supported, allowing automatic spacing adjustments between characters from different scripts.

Starting with Firefox 145, support has been added for CSS module scripts, disabled by default using the preference layout.css.module-scripts.enabled. CSS module scripts allow for CSS scripts to be imported like ECMAScript modules using import attributes.

Starting with Firefox 145, Nightly builds now support CSS anchor positioning, which allows to tether elements together. The anchor-positioned elements can then have their size and position set relative to the size and location of the anchor elements to which they are bound.

Starting with Firefox 145, the Trusted Types API, primarily aimed at preventing cross-site scripting attacks, is now enabled in Nightly.
