The Scripts were recorded on IE and i tried to run the scripts on IE 6 and IE 7.0 which worked fine but the same scripts when i tried to run on Firefox the script execution was typically slowdown. Can any one please tell me why it has happened so and is there any Private patches available for firefox to fix this issue.

Or else is there any alternative to overcome this issue please guide me earliest as it is very critical for me to execute the scripts on Fire fox

Note: I am using QTP 9.1 & browser Firefox 1.5
