[🚀 Feature]: read browser config

[dornech]

Feature and motivation

When connecting to existing browser sessions, it might be helpful to read config data like the current download directory. Currently I think this is only possible via calling the internal settings-page and then searching for the key.
I wonder if it is possible, to make the access to settings more straightforward.
I think of a webdriver method to download the config as JSON.

I understand somthing like this was discussed here but there was no real follow-up?
