Lol.. I used that one for a bit, but prefer old school so I don’t forget (again) how to do HTML... (guess I still need to update how to use HTML5, not sure of the differences yet).
With my stiff arthritic finger and limited html knowledge, I used the BBcodeXtra FF extension, which is also available on FF quantum, as bbCodeWebex. The Custom option enables you to make scripts to do such operations as pasting what you have copied into html formatting etc. In
Firefox, select the top paragraph and right click and choose View selection source to see the coding for that.
