Every time I upgrade seamonkey-bin, it makes /opt/seamonkey/plugins a folder with only libnullplugin.so inside. In contrast, firefox-bin keeps "plugins" as a symlink to /usr/lib32/nsbrowser/plugins ; I'd like semonkey-bin to do the same, or at least preserve the symlink if I make it manually.
Fixed in seamonkey-2.4.1
