well we have IETester tool to check a template with different versions of IE but what about other browsers .
I have Last versions of firefox , chrome and opera and I try my template with them .
questions :
1 - do other browsers have the same problem as IE in their different versions ( IE6 has one standard , IE 7 another , IE 8 its own , IE 9 is something else ! ) , so necessary to check template in older versions as we do with IE ?
2- if yes , how to do that ? any tools ?

Tools for testing cross browser compatiablity include:
