the ebuild is buggy. it looks like a firefox ebuild was used to make the thunderbird ebuild. there are two lines in that ebuild that should be changes from declare MOZILLA_FIVE_HOME=/opt/firefox to declare MOZILLA_FIVE_HOME=/opt/thunderbird DIFF: 37c37 < declare MOZILLA_FIVE_HOME=/opt/firefox --- > declare MOZILLA_FIVE_HOME=/opt/thunderbird 54c54 < declare MOZILLA_FIVE_HOME=/opt/firefox --- > declare MOZILLA_FIVE_HOME=/opt/thunderbird Reproducible: Always Steps to Reproduce: 1.emerge mozilla-firefox-bin 2.emerge mozilla-thunderbird-bin 3.try to start firefox-bin Actual Results: firefox-bin does not start any more Expected Results: thunderbird should have been installed in the right directory and both applications should be usable. diff output of the repaired ebuild: 37c37 < declare MOZILLA_FIVE_HOME=/opt/firefox --- > declare MOZILLA_FIVE_HOME=/opt/thunderbird 54c54 < declare MOZILLA_FIVE_HOME=/opt/firefox --- > declare MOZILLA_FIVE_HOME=/opt/thunderbird
Just found out it is already fixed, sorry
