Rated 4 out of 5 stars

Excellent add-on. Helpful in seeking assistance with issues with add-ons

However, the "Save as" feature saves the file as a generic file even when I ask it to save it as a text or html file

This review is for a previous version of the add-on (1.12.0). 

Version 1.13.1 adds the file extension if needed.
