On FF on quite-old Android 7.0 I chose share (within the web page), then "copy to clipboard" and the text is:

Not quite what I was expecting! If I send to notepad then the first line is "null" and the second is the address as above.

I did 23s but I think the grid form makes it much slower, I prefer it Countdown (a UK television quiz) style, just in a row.
