SUMO support forums are best described as "aged" and awkward. You come here with drag and drop attachments. A fairly comprehensive composition toolbar with useful functions, emoji, font selections. Then you go to SUMO. Poor cousin does not begin to describe the difference.
It is time for Mozilla to "standardise" their websites with regard to composition features. I should not need to have a collection of skills to insert an image into a topic or format the text, depending on which Mozilla sponsored site I am on I can use markdown (with instructions from github), raw HTML and here whee I just paste. Paste should work everywhere.
