actually, I spoke too soon about sorting the colour in the button “remove categories”
In Firefox it is fine, when not signed in.
in Chrome it is still bright red (have cleared the cache and cleared browser) when signed in

I did not have any appearance problems between browsers yesterday – I know this as I use both – I have 2 screens and usually keep Chrome not signed in, and firefox signed in, i am regularly checking things and getting links for customers.

I obviously have many customers using many different browsers.
