@Jogar the Barbarian
Thanks for creating and hosting this update (http://supersilly.com/~greg/storage/smilie_inserter-0.7.0-tb.xpi)
You rock!

FWIW:
Working in TB 3.1.9.
For folks worried about malware:
I scanned the xpi with Malwarebytes before install, and did a system scan after install, it's clean.

Many thanks!!!!
