The most beautiful and ‘ergonomic’ theme, I love it!

Thanks for your help and answer, but I use a PPA to get the last updated stable version of Thunderbird. Indeed, I found a better idea for the moment: using the addon Disable Add-on Compatibility Checks. Then I can use your theme.

This review is for a previous version of the add-on (10.0.3). 

Try to install Thunderbird 44, my beta version works with it. Here is a link where you can find it:
- http://download.cdn.mozilla.net/pub/thunderbird/candidates/44.0b1-candidates/build1/win32/
Just open the directory with the desired language and then download the file with the ".exe" extension. The link I provided you above is for Windows. If you need a Linux version, you can find it here:
