i used IE 7 while scripting . using object spy i made my script fully descriptive. scripts are working fine with all IE version(6 & 7) .How can i make those same script running for Mozila firefox 2.0 browser. i havn't use any "Type" and these kind of properties which specifies the browser. i have used browser "title" , "name" and all those properties which are same for IE as welll as Firefox. But while running the script in firefox it is giving error message on first line of code itself as "Browser properties not matched."
