This extension works with TB 60 and modifications indicated by j917863 but "options" does not work. An other modification has to be made in the internal file options.xul (in chrome/content/). add in line 2 :
<?xml-stylesheet type="text/css" href="chrome://messenger/skin/preferences/preferences.css"?>
as indicated in https://wiki.mozilla.org/Thunderbird/Add-ons_Guide_57 , § "Changes in thunderbird59"
I have also modified chrome.manifest by replacing the line concerning customizeToolbar :
style chrome://global/content/customizeToolbar.xul chrome://slideshow/skin/slideshow.css appversion<59.0a1
style chrome://messenger/content/customizeToolbar.xul chrome://slideshow/skin/slideshow.css appversion>=59.0a1
