Hi, the package "firefox-beta" <http://aur.archlinux.org/packages.php?ID=19795> (http://aur.archlinux.org/packages.php?ID=22244) does not seem to be taken care of by his current maintainer. I uploaded "firefox-lorentz" ( firefox-lorentz) which is the 3.6.4 beta version. Beta versions, and stable versions too (like nvidia-beta), must be in firefox-beta.
