when entering the following code in the editor using Firefox:

 

<td style="background: url(/images/stijl.jpg) no-repeat ;">

 

and then switch to normal and back to html he changes it into:

 

<td style="background: transparent url(/images/stijl.jpg) no-repeat scroll 0% 0%; -moz-background-clip: border; -moz-background-origin: padding; -moz-background-inline-policy: continuous;">

 

resulting in very messy code. How do i resolve this?
