Firefox colours for 21.10

Had a brief look but Firefox that is part of the Budgie / Ubuntu package can’t see where you can get the new FF Colours themes etc and although there are add-ons called Colours its not the one that is presented to install when installing FF from new on Windows, any ideas or links greatly received.
TIA

Are you referring to Personalize Firefox with Colorways | Firefox Help ?

Hi

Thanks for link - it was what i already had but wasnt how i expected it to be prompted to use for some reason - prob not enough coffee today yet, thanks anyway

You have indeed Colorways for a selection of a few pre-made variants in the coloring of elements.
Then there’s also Firefox Color which is pretty amazing. You can pick your color per element without going through the hassle of modifying a userChrome.css file.
