Some text-heavy, not all, sites are now displaying with a darkish blue background (like the trousers on U.S. Army dress blue uniform) which makes the black or sometimes two-tone text on the page really hard to read. This happened after I disabled an ad blocker, as far as I can tell, but I'm not sure about that. Here is a site producing this problem: https://www.foreignaffairs.com/articles/2018-01-20/trumps-lucky-year?cid=nlc-emc-fa_paywall_free_eliotcohen_ma2018_prospects_b-20180120 Is there a way to return sites to a white background? Thanks.
