I would like to use the add on, to mark different recurrent sets of words to organize my workflow. Seems to work pretty well. The add-on would be of even more use, if there was a way to mark certein setzt of information belonging together in a certain colour and other sets in different colours. For Example I have ten different word I would like to mark red and tenn I would like to mark green, because they lead to different decisions and actions within my workflow. Up to now I used the "multiple highlighter" tool which does not work any more with Firefox Quantum and I cannot find an alternative for that. Your tool would work great with the option of different colours.
