Can i align the caption of a button (input type=submit) to the left or right for Internet Explorer? - firefox caption

I have a kind of control:

This type of input

I want to do is set the right property on the left or right in Firefox, the title is left justified by default, but is centered on for Internet Explorer (IE7).
Is there a way to define the orientation? I tried on the characteristics of this style

: textAlign left;
padding-left: 0px;
text-indent: 0px;
caption-side: left;

but without success
Thank you in advance for the answer
