Thunderbird Support Forum

If you have enabled the Menu Bar, maybe you find it is the same colour as the Unified folder and want to change it. Maybe you want to change the colour of the opened Tabs. Read the information below to help you use 'userChrome.css' and tailor make your own Thunderbird.

If you want your 'Message List' to use alternative colour stripes often refered to as zebra style then I have put together some code and instructions on how to create the effect.

Obviously you may need to modify the actual colours used. The following works on a Light theme. The striping is white and pale grey. On hover the text is black on a pale blue background. On select the text is white on a light blue background, but strong enough to show white text clearly.
