After update to version firefox-bin-28.0-r1 (from -28.0), the application won't start anymore. Instead, there is a dialog box saying "Failed to read the configuration file. Please contact your system administrator.". Applies to both existing and new user profiles. Reproducible: Always
Same thing here. Now writing from firefox-bin-24.4.0, since maintainers removed the ebuild for 28.0, which worked fine.
Was a minor typo I introduced into all-gentoo-1.js. It has been fixed and added to tree.
