Re: dw.com freezing PM
Confirmed. careful clicking the above link it may freeze your browser -- the problem seems to be an endless or recursive loop that causes severe memory inflation.

Re: dw.com freezing PM
OK, so the culprit is promio-connect.com -- their (newsletter) script causes endless allocation of their form container on the page.
Use your adblocker to block the domain promio-connect.com or system.promio-connect.com and you'll be able to safely load the page.
Seems to be an effective ABL rule to prevent this issue without any loss of functionality on the page.
I've contacted dw.com with details of my analysis.
As far as I can tell this is a recursive scripting call (which are notoriously hard to catch or prevent) in their newsletter container scripting which causes an endless creation of DOM container nodes eating memory and locking up the event loop in the browser. That isn't a browser bug as the browser is simply doing what it's told, but unfortunately does result in denial of service for us.
