It was interesting to come across this thread. I was hoping to run two (or more) Firefox instances simultaneously using FF.au3 but without much success.
I am launching each Firefox instance with a separate MozRepl port number (and with the -no-remote flag) but I am not able to successfully control the separate Firefox browsers using _FFconnect.
I had hoped that simultaneous, independent operation of multiple Firefox browser sessions was possible, has anyone been able to do this?
Much thanks for any advice
