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&lt;59.0a1
style chrome://messenger/content/customizeToolbar.xul chrome://slideshow/skin/slideshow.css appversion&gt;=59.0a1

I like this extension (v1.0.1) which now works also with TB3 beta. Just a small problem. You have named a button button-forward. This makes a problem with standard buttons because one of them has the same name, so in several themes, this makes TB confuses standard icons withs yours. There was not this problem with the previous version (0.9, I think).
But anyway, nice extension.
