If you shop online with Sainsbury's and want to get rid of the new incredibly annoying ads they've put in your favourites list, add these filters to uBlock Origin:

sainsburys.co.uk##div[data-testid="tracking-product-view"]:has(> div[data-testid="sponsored-ad-impression-tracker"])

sainsburys.co.uk##div[data-testid^="ingrid-ad"]:has(> div[data-testid="citrus-banner-container"])

Show your ads for sugary bullshit to someone else.
