Avast! WebRe is the interestinf feature. But it seems that when using IE9, the position of Avast! WebRe bar is not suitable. It takes much space
This is due to the internal structure of IE 9 and cannot be changed, unfortunately.
If you use the menu-bar in IE 9, you can unlock the bars (right-click on the bar) and then move the webrep-bar besides the menu-bar to lessen the used space.
This leaves the menu bar visible however as some don’t want this.
No other solution, sorry.
Firefox. 
good idea 
;D Yes, of course. But that wasn’t asked for, I’m afraid.
