Firefox browser is part of the LoadRunner deployment and is used for development of scripts in TruClient protocol. This protocol has very strong dependency and can only work with the exact version of the Firefox browser it was built with.
As a result, even if any security vulnerabilities are discovered in the Firefox browser, you cannot upgrade the build-in Firefox version, as it will break the TruClient protocol using Firefox. The upgrade is performed in the next LoadRunner release.
As a workaround, users who do not use TruClient Firefox protocol or have security vulnerabilities with the built-in version of Firefox can remove the Firefox binaries from the installation folder without affecting other functionalities.
To delete the Firefox binaries:
1.Navigate to bin folder.
2.Locate the ''firefox'' folder and delete it.
Once deleted, the folder can be restored by running the ''Repair'' installation procedure.
