I'm not really sure what the difference is, but and here is some alternative code for userChrome.css from a link in the linked mozilla bug.
#threadTree > treechildren::-moz-tree-row(odd) { background-color: -moz-oddtreerow !important; } #threadTree > treechildren::-moz-tree-row(selected) { background-color: -moz-cellhighlight !important; } #threadTree -> treechildren::-moz-tree-row(selected, focus) { background-color: Highlight !important; } -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1228009 Title: Regression: Zebra striping is no longer present Status in “thunderbird” package in Ubuntu: Confirmed Bug description: I upgraded Thunderbird yesterday (19 Sep 2013) to 24.0+build1-0ubuntu0.13.04.1. I upgrade packages almost every day, but (from /var/log/apt/history.log) it seems like the previous version was 17.0.8+build1-0ubuntu0.13.04.1. (v17 to v24. Is that correct?) Upon restarting, the zebra striping in the list of emails is no longer present. I'm using the default theme (Default 24.0, last updated 19 Sep 2013). I've also tried restarting in safe mode, but the zebra striping is still absent. The background no longer alternates, instead displaying the same white colour for all messages.
