in thread some doubts on my first steps with WWW::Mechanize::Chrome

You have to manually launch "your" (the first) Chrome instance with --remote-debugging-port=922.

Afterwards, if you launch a WWW::Mechanize::Chrome program, you tell it to connect to an existing tab and it should connect to the already running Chrome instance which has your cookies etc.
