The binary installation files for firefox-5.0 are not available anymore at the mozilla download server. firefox-bin-5.0 therefore won't install. Reproducible: Always Steps to Reproduce: 1.emerge firefox-bin 2. 3. After renaming firefox-bin-5.0.ebuild to firefox-bin-5.0.1.ebuild, and doing an 'ebuild digest', I could easily install firefox 5.0.1. Please bump firefox-bin-5.0 to firefox-bin-5.0.1.
Fixed by removal of 5.0, and addition of 6.0. This also won't happen again due to an SRC_URI change.
