Old HTML5 Games not working?

I have been testing some featured games at the arcade, and all them froze after a few moments:

This happens to me both on Chrome and on Firefox...

Maybe due to the following:

Disturbing...

Yep, Chrome broke all games published in 2012. We filed a bug report with them and they declined to fix it. There's more details in that thread. Long story short all that old content needs to be re-published, which affects all web content, not just our own arcade.

Our Arcade is in need of some upgrade work and we have it planned, and largely because of this I think we will require all games to be re-submitted when we relaunch it.

How can Google do this? They're also gonna cause big problems for the Unity Player mid 2015 too.

As you said Ashley, all HTML5 games are affected and i know that Gamemaker are also having to modify their HTML5 exporter
