So the new chrome update is launching soon (Check out how to handle the change). Chrome has launched it to it's Beta channel. Not live yet. I am sure will be a few weeks away, so you still have time.
I wanted to share with you a couple options so you can test how your ad will render in the new upcoming release with your current browser. Version 45.
Option 1 -
You can download the Beta version of Chrome from here. https://www.google.com.au/chrome/browser/beta.html
If you are on the latest version of Chrome Version 45.
in order to enable / disable this feature,
Go to Chrome Menu > Setting > Show advanced settings > Content Settings or shortcut link below: chrome://settings/content/
Then, Scroll down to "Plugins" (as per screen shot below)
