thecrazytony [1] filed a orphan request for firefox-nightly-zh-cn [2]: This package has been discontinued to maintain since 2018, and the link inside (from firefox homepage) are upgrading once a day. So this package is definitely out-of-date. [1] https://aur.archlinux.org/account/thecrazytony/ [2] https://aur.archlinux.org/pkgbase/firefox-nightly-zh-cn/
