Thanks to @mmirG mentioning Firefox for Android is able to run all regular add ons, I have tested COLLECTION HIGHLIGHTER with Violentmonkey in Firefox for Android and it worked!
I should soon receive and use my wife’s old Android phone (I have Windows), I cannot wait to be able to test all scripts but most of all to be able to check my highlighted collection on the go, in CD stores!
It is the best 
PINNED SOLUTION so far!
