Instead of building this yourself, please use the repository from https://bbs.archlinux.org/viewtopic.php?id=117157.
Not only do you skip the very time-consuming builds, but the published package also has debug symbols at Mozilla's crash reports service, which helps tremendously with finding or filing bugs for any crashes you get.
I consider this the canonical
firefox-nightly
package for Arch Linux.Alternatively, download Firefox Nightly straight from Mozilla, extract it to a writable place (e.g.
~/.local/firefox-nightly
) and let it update itself using the integrated updater.
