Upgraded to firefor for android mobile 8.0 and cloud printing stopped working?

After upgrading to firefox 8.0 on my android devices (phone and tablet) and intalling cloud printer 1.0.2 addon the cloud printing stopped working. When I try to cloud print I see my printers select the one I want and it says Print job added,but no printing occurs. I go to cloud printer manager and it says no print jobs. Cloud printing used to work on old version of firefox the on preceding 8.0. I know google cloud printing works because I can go to gmail webmail in a browser (not firefox) and print a gmail message via the cloud and it works. How can I get old version of firefox back on my mobile and why does'nt new version work?
