and Firefox's "MurdochAlert"
https:addons.mozilla.org/en-US/firefox/addon/MurdochAlert-details
Have been added to their app lists. Both are new and still need some tweaking per user reviews.
I haven't tried either of these yet but they sound intriguing. I'll probably install the Chrome app and give it a whirl as I'm not interested in following links that lead to News Corp websites.
