Objects are not recognized in firefox 12

[pradeep singh]

Also I faced another problem. I installed chrome patch QTPWEB_00120.EXE for chrome version 24 and I have also checked in chrome browser ,in extension 'QuickTest Professional Agent 11.2475' was present or not and it was present. And also object spy could able to recognize the objects efficiently. But later doing R&D for firefox browser ,I uninstall patches (QTPWEB_00120,QTPWEB_00122 ,QTPWEB_00090,QTPWEB_00092 ,QTPWEB_00100) from control panel .
Then again I installed QTPWEB_00120,QTPWEB_00122 patches but still objects on firefox are not recognized and also objects on chrome are no longer recognized.
Please let me know what to do? Should I again uninstall all patches or uninstall QTP and how ?
