Version 123.0beta, first offered to Beta channel users on January 23, 2024
Firefox Beta gets updated 3 times a week and as a consequence, the release notes for the Beta channel are updated continuously to reflect features that have reached sufficient maturity to benefit from community feedback and bug reports.
Warning: Features listed here may or may not make a final release of Firefox.
In addition to these release notes, you can follow ongoing development via our @FirefoxBeta Twitter account.
When translating web pages, we are now also translating text in tooltips (i.e. titles) and text displayed in form controls (i.e. placeholder).
Address bar settings can now be found in the Firefox Settings' Search section.
Previously, SVG feImage elements that pointed to SVG content required the SVG document to have a root element that had non-percentage width and height values. Such content will now fall back to use the default replaced element values of 300px width and 150px height and the feImage will no longer fail to render.
By enabling Preload and Modulepreload support, Early Hints are now fully supported.
Audio echo cancellation can now be applied to microphone inputs when the audio output is redirected to another device with setSinkId().
Firefox now supports declarative ShadowDOM, providing developers greater flexibility and improved ergonomics when working with ShadowDOMs directly within HTML.
Some machines with older AMD CPUs may see image thumbnails incorrectly render as all black in file dialogs. If this is the case, updating the graphics driver should address this issue.
