Firefox-bin version 18.0.1 has been released; 18.0 is the current version in portage. On my ~amd64 box, just renaming the 18.0 ebuild to 18.0.1 allows it to install and run fine; I'm writing this from the new version installed through a local overlay. Reproducible: Always
+1: I also renamed the firefox-bin-18.0.ebuild to 18.0.1, and I was able to update to the latest 18.0.1 version without any problems and without any other changes. ... Please update portage. Thanks! :)
In cvs will hit mirrors shortly.
