If you use Google’s web browser Chrome, you might notice that Unity games embedded in web pages no longer work as of the latest update. As they’ve planned to since 2013, Google have disabled support for the way the Unity plugin works. Unity 5 does support WebGL, which works without plugins, but for now that’ll leave a whole load of browser games not working. You can re-enable support temporarily, if you don’t mind digging in settings, or simply use a different browser.
It’s been a while since I had to fire up another browser to visit certain websites that wouldn’t work properly in mine. It’s like the browser wars all over again!
