To wrap up January, we are proud to bring you the release of Firefox 85. In this version we are bringing you support for the :focus-visible  pseudo-class in CSS and associated devtools, <link rel="preload"> , and the complete removal of Flash support from Firefox. We’d also like to invite you to preview two exciting new JavaScript features in the current Firefox Nightly — top-level await  and relative indexing via the .at()  method. Have fun!
