Just found this;
And I guess it means there wont be any webplayer support for chrome or firefox. 
Boo,…da man is try’in ta keep us down!
will portals like Kongregate and Wooglie be affected?
So how do we play web made games with Unity now?
Can’t they use Pepper?
Same way you always do; they haven’t disabled Unity yet and won’t for a while. Also, you could always use another web browser.

Well Unity has until the end of 2014 to do something.
Perhaps its time to rethink HTML 5 support?
Problem with HTML5, is that, similarly to Flash, it lacks support for locking mouse. No browser based FPS games made in Unity for you!
Meh… not surprising, a browser is content browser, not an operating system. Browser based gaming filled a need at the time (and helped change gaming in general), but that need is now served in better ways.
Lol, yeah, thats the problem! And I’m pretty sure you can lock the cursor in HTML5.
It would be nice to hear something from an actual Unity representative about what their plans are for this. This is a big deal for web developers.
Silverlight is used by Netflix, so there’s more than one big company with a financial stake in figuring out how to handle this change. (In addition to all the games that use Unity in the web browser.) There might be some growing pains, but I would bet that ultimately we’ll just transition to the next big thing… until that architecture is replaced by the next bigger thing just as is happening now. 
Holy crap?!
With Chrome you can export to NaCL, and with Firefox it looks as if they still support the plugin - it’s just that the user will have to click on it to get it to run.
Ugh. While Unity will probably be able to export something that works with each of the relevant browsers, it’s still less than ideal to need multiple builds to hit them all. How unfortunate.
Indeed. This isn’t “no more plugins in Chrome,” it’s “no more plugins built around an API that is almost old enough to legally drive.”
Obviously it’s being discussed at Unity Towers. We don’t have any official response yet, but obviously don’t want all the games made by all our customers to suddenly stop working. We’ll figure something out.
Presumably they will simply replace it with something better and Unity will adapt.
Netflix for some time has been working towards using HTML5 and “Premium Video Extensions” where possible. The move from Silverlight has been in progress for some time now it would seem.
I don’t currently target the web player for anything more then quickly testing small project iterations between coworkers and friends, but I am very curious to see how Unity deals with this arising dilemma.
OMG I am working for client who is building facebook game… is untiy-facebook gaming in trouble now ???
