Re: Difference in HTTP Protocol Recrding with IE/ FF?
Be pragmatic. Record with HTTP and then playback with HTTPs for those calls which support it.
ON recording with Firefox, be sure to examine the requirements documents for your version of LoadRunner to see which browsers and which OS's are supported for your release. You may not think it makes much of a difference but if you are using an unsupported environment and you attempt to call or contact HP support then you will reach a limitation of support very quickly until you can demonstrate the same set of issues exists on a supported environment without an unsupported item installed in the environment (and possibly altering common libraries)
