MarsSeed [1] filed a deletion request for firefox-kde [2]: Orphaned, more outdated variant of another AUR package: https://aur.archlinux.org/packages/firefox-kde-opensuse The latter also needs update, but at least has a maintainer and has 334 votes. This one only has 2 votes. I recommend deletion and not an AUR merge. As the few comments here only pertain to this specific build and are also old now.
