This is going in AO 2.0.2 (out later today) and will in the future also be added to WP YouTube Lyte and WP DoNotTrack (both of which have a smaller reach).
If you’re a plugin or theme developer and want to warn your users as well (without blocking them), here’s the code I used (do change the translation-domain from “autoptimize” into one that is applicable to your plugin):
You are using a very old version of PHP (5.2.x or older) which has serious security and performance issues. Please ask your hoster to provide you with an upgrade path to 5.6 or 7.0','autoptimize'); ?>
Just read an article on BBC News that starts of with the AdBlock Plus team winning another case in a German court (yeay) and ended with a report on how Firefox also has built-in tracking protection which -for now- is off by default and is somewhat hidden. To enable it, just open about:config and set privacy.trackingprotection.enabled to true. I disabled Ghostery for now, let’s see how how things go from here.
Although the number of pageviews of this blog already decreased from approx. 2100 pageviews per week before mid May to 1300 pv/week after (I never thought I’d ever be hit by a Panda), yesterday was an absolute disaster. Turns out that Automattic changed the domain of the Jetpack stats tracking pixel to pixel.wordpress.com, which WP DoNoTrack (for which I pushed out a small update in May) blocked as that domain was not whitelisted. The downside of white- instead of blacklisting.
