To Verify your application will work with LoadRunner TruClient web (Firefox) built-in version

1. Find the Firefox folder from ''...loadrunnerbinfirefox
2. Right click on the ''Firefox'' folder and select ''send to ... -. Compressed file'' to make a back of the folder,
3. Copy the ''Firefox'' folder
4. Paste it on the desktop
5. Open the folder and invoke the browser from there run the ''firefox.exe''
6. Test your application manually
a. if does not work check with your developer for minimum Firefox version supported. If it didn't load assume that the application requires a newer Firefox version ( upgrade to newest LoadRunner version and try again)
b. If it was loaded try opening a private browsing tab and try again. Maybe it is related to the fact TruClient runs the browser in private browsing mode

Remember do not update this version!!
