looks like esr115.33 is the last version for Win7 according to the chart. Haven't seen any info if it will continue after March 2026. https://whattrainisitnow.com/release/?version=esr
it would still be better to have a native dark mode in Firefox. I am using an extension "dark mode" and moving the switch up and down can get all pages dark, including this site, but it takes a few extra steps each time to do this.
