+I've been using [Kitten
+Block](https://addons.mozilla.org/en-US/firefox/addon/kitten-block/) for
+years, since I don't really need the blood pressure spike caused by
+accidentally following links to certain UK newspapers. Unfortunately it
+hasn't been ported to Firefox 57. I tried emailing the author a couple of
+months ago, but my email bounced.
+
+However, if your primary goal is just to block the websites in question
+rather than seeing kitten pictures as such (let's face it, the internet is
+not short of alternative sources of kitten pictures), then it's easy to do
+with [uBlock
+Origin](https://addons.mozilla.org/en-GB/firefox/addon/ublock-origin/).
+After installing the extension if necessary, go to Tools → Add-ons →
+Extensions → uBlock Origin → Preferences → My filters, and add
+`www.dailymail.co.uk` and `www.express.co.uk`, each on its own line. (Of
+course you can easily add more if you like.) Voilà: instant tranquility.
