How do I disable the Market App Fast Web Install feature in my android phone settings? I do not quite like the Fast Web Install idea of Market app.  

I use AppBrain for my app installs and it lets me manually select if-and-when I would like to install or update an app selected from my AppBrain account to my phone. 

That is (I noticed) not the case with the Market app. So, if I (or someone gaining access to my google account) were to select an install from Market, it would just get installed on my phone shortly -- no questions asked. 

Similarly, I prefer to install apps when the phone has a Pass-Through or WiFi data connection. But, this auto-triggered install can happen any time -- I don't like that either. 

I could not find any settings in my Market app that will make it ask before it downloads and installs an app. I would like to control this at the phone (rather than from my Market account login).
The Fast Web Install feature relies on Background Data being enabled.  If you turn this off, (Settings > Account &amp; Sync > Background Data) any apps you select in the Market website will not be downloaded to your phone.

When you switch Background Data back on, anything you (or your nefarious account accessor) have queued will be downloaded.
