Need help with Unity web player

It used to just have settings, about, and fullscreen. But now my web player’s right-click menu just got a new entry that it NEVER had before! That menu entry is a submenu called “release channel”. How do I remove this? I think it did some kind of auto update, and I don’t want this extra menu. A developer might find it useful for trying out different versions of the web player (beta, stable, release, etc) but it’s USELESS for anyone who’s not a developer. Please help me to get back my old version of the Unity web player (some 3.x version). It was simply all I needed to play this one web game (that was all I downloaded it for in the first place). But now its rightclick menu had become overbloated with extra useless stuff, that only a developer might find interesting.

Unity cannot remove it because its by default in a unity’s new web player. If you want to remove contextmenu there is one option in build setting and its no contextmenu.
