Scroll to Text Fragment (i.e. #:~:text=…) has had poor accessibility and we’ve been slow to implement it, wanting a better solution. As of https://bugzil.la/1914877, Firefox now supports this feature, highlighting the range to assistive technologies to support better accessibility.

PSA; We have paused Nightly updates due to a functional regression (https://bugzilla.mozilla.org/1903197). We are backing out the regressor and spinning new builds. Updates will be restored in a few hours.

Relative Color Syntax is shipping in https://bugzil.la/900251 Previously, color functions could only specify colors in an absolute manner. The new relative color syntax extends modern color syntax to allow existing colors to be modified using the color functions.

Sometimes small changes can make a big difference. Recent compiler flag changes for compiling Firefox for Android have improved responsiveness, reduced page load times and extended battery life. See https://bugzil.la/1894716 for details.
