State Partitioning is an interesting privacy feature shipping with Firefox 86.

In other words, every first party and its embedded third-party contexts will be put into a self-contained bucket. Applies to every embedded third-party resource …

Date/Time Input Types are coming to Firefox, and I must say they look quite good too (as a reference: here’s how Chrome implemented this): The implementation also looks familiar, doesn’t it? 😉 The date/timepickers are currently locked behind a flag in Nightly. Change dom.forms.datetime in about:config if you want to try them out already. Date/Time …
