While Firefox 60 marked the Quantum series as ready for enterprise deployments, Firefox 61 will focus on performance enhancements and improvements of all sorts. For starters, Firefox 61 promises to enable faster tab switching on both GNU/Linux and Microsoft Windows platforms and makes WebExtensions run in their own process on Apple’s macOS. Talking about WebExtensions, Firefox 61 will improve the way they manage and hide tabs. Mac users are also getting a new feature in the Page Actions menu that allows them to share the current URL with the sharing providers from macOS, and it looks like the dark theme will receive various improvements for a more consistent experience across Firefox’s user interface.
