I know the addon you are talking about and I use it all the time as it’s the only reason I still put up with Firefox as they “update” it every 14 days and always break something useful with their “improved” codes. It’s invaluable as it allows immediate coding of images, URL’s plus italic’s, bold, etc. It also does the same for BB forums.

However, I’m on my iPad now and away from the PC with the addon. I’ll get back with you later on today.

Below is the one I use that serves the same purpose:

This is an extension for Firefox 57 and Later, which allows you to apply commonly used tags, and create custom tags for bbCode, vBulletin, Html, XHtml, and Markdown.

Also Word Count for checking excerpt length while posting articles:

Counts words and characters in selected text.

I use this one to show my most frequently selected web pages:
