Unity Web Player forces me to update him to Dev

I have 4.6.6f2 (Stable) version. But any Unity application tries to update Unity Web Player to 5.x.x Dev version which can be used for development, but NOT for gaming. It really forces me to do it (if I cancelling update, browser stucks for 5-10 seconds). I'm on STABLE channel (Alt + Right click, I know). I have Unity IDE installed, but in my Chrome I using 4.6.6f2 version (I checked in chrome://plugins, there is no 5.x.x version)

What I need to do to save ability to produce Unity applications BUT also save ability to play Unity games?
