Prior to your update of this add-on, I could save any .xml page as a single .html file with a single click. As of 5/19/18, I get an error message, it won't save it at all, and much time spent setting the options on the add on is fruitless. I have relied on this add-on for months to simply convert my newsfeed xml to a single html document for viewing online, and I've pointed search engines to this html file. Now this add on doesn't work do this at all, and I'm spending time on a Sunday I needed to spend elsewhere trying to fix something that wasn't broken to begin with. Please re-enable this capability with the awareness that I am experiencing real and significant harm by relying on an add-on your making it available invited me to use only to suffer precisely because I accepted your invitation to use it. By any reasonable standard, that's not good.
