Firefox Colour only shows the top half of my theme and blanks out lower half and current page “block”.
Also this theme “Strawberry Temptation (Laptops)” only shows three faces out of the five when submitted via AMO
to have total transparency, you must position the lever at the bottom, thus obtaining all the values at zero 
Thanks Candelora have liked the themes you publish. I don’t have the problem with AMO but in Firefox Colour where I would like to see how a theme looked before offering it for approval.
So I thought try a “private” one and although that has been approved and I can see it listed with a bit of green jigsaw puzzle on my Developer’s Hub Page it will not download. And the web page given in the approval e-mail is not recognised when I am signed in.
