The issue affected Firefox Nightly at the time but it seems to have been included in the beta and stable releases of Firefox 85 as well. Mozilla's update to Firefox 85.0.2 resolves the issue.
Firefox users may select Menu > Help > About Firefox to check the installed version and run a manual check for updates. Users whose version of Firefox is unresponsive may download the new release from Mozilla's official download site to install it manually after the download completes.
