Firefox 140 Released With "Unload Tab", CSS Custom Highlighting API
Mozilla Firefox 140 release binaries are available today as what's going to be the web browser project's next Extended Support Release (ESR) version.
Now you can easily unload desired tabs to help reduce Firefox memory use and conserve CPU resources by unloading tabs that don't need to be loaded at that moment. Firefox 140 also finally supports the CSS Custom Highlighting API for styling arbitrary text ranges. New experimental features with Firefox 140 include the Prioritized Task Scheduling API within nightly builds and Atomics.waitAsync.
