Configure your browser to use Gatling Recorder’s proxy.

How is that done in i.e. Firefox?

In the documentation is says that this has to be done in order to use the recorder.

Thanx!

Come on: there's even Firefox screen captures in the documentation!

Ok, here is what I did:

*I started a local web-app on localhost:8080.

*Then I configured Firefox to use manual proxy configuration

*Then I started Gatling recorder with the .bat script.

*Going into my web-app on localhost:8080 in Firefox did not result in any "activity" in the Gatling recorder.

*Changing the web-app to run on port 8000 results in the stacktrace below when starting up Gatling recorder:
