How can I fix image zooming in Firefox?

I am using openSUSE 11.2 64-bit and I would like to fix image scaling in Firefox so that images are less pixelated when zoomed in. This is the fix I used for Ubuntu: https://launchpad.net/~firefox-smooth-scaling/+archive/ppa

Can I use this fix for openSUSE? If so, how? If not, then what can I do?

Any responses will be appreciated.

Thanks.
