The whole point of the safe zone is it is operating completely isolated from your normal desktop. Plus having only one browser available in the safe zone saves a massive amount of work to include a browser of choice as the safezone browser is heavily restricted when compared the a sandboxed browser.
There is nothing to stop you using either Firefox or IE sandboxed in the avast sandbox. I don’t know how the others work in that regard (I’m an avast user not employee), as far as I’m aware the others are sandboxing and not using the same functioning as the avast safe zone.
