BPM 9.25 : TruClient scripts load mode are launching firefox

Hi,

 

Since we migrated to BPM 9.25, we discovered that our TruClient FF scripts are running the process firefox.exe when executing, which is taking lot more resources than before.

In my head, the load mode should not run firefox, instead of interactive mode. Can I have an explanation please?

And is there any way to get back to a load mode without using firefox?

Thanks in advance.
