Safari 9 for Firefox (Mac only)

Styles Firefox to look like Safari 9 from OS X Yosemite and above. In addition to the basic Safari layout, many of the main icons and animations are reproduced using embedded SVG and CSS transitions. Additionally, under OS X 10.11+, the San Francisco typeface is used in more locations than stock Firefox. ***This style was designed for Mac OS X users and currently does not work properly under Windows, Linux, etc*** Designed with Firefox 50 on a HiDPI Retina screen.

Thunderbird Artux 3 panes

A bit like Gmail/Outlook look&feel, based on chrissi4u's 'CLEAN ADAPTION no1' designed for vertical message view. Note that you will have to adjust the width of the panes for the message list to display correctly AND you should arrange the columns in the following order: STARRED, ATTACHMENTS, SUBJECT, SENDER, DATE, SIZE. Or you can experiment with those. Not guaranteed to work with every window manager.
