Review for Dark Shadows XT by Firefox user 4d9175
Rated 5 out of 5 stars
Without a doubt, these are the best skin series for Thunderbird and Betterbird. They maintain their integrity even when the mail client is maximized on a 16:9 (widescreen) monitor, where most skins break on the left of the top bar. Additionally, the color contrast is just right, Amazing. True that a grey logo will play better in the title bar
