@romit In BAS 0, this is not a tab, but as it were, the initial page of the browser and it cannot be closed, only the following can be.
If 0 close it, then the stream itself closes as it were :)
The browser seems to be closed.
Oh, so that's how it is, okay, I hope this problem will be resolved quickly by BAS, even if there is a change in format, BAS can provide lessons so that the Fingerprint and Proxy settings can run well.
I think you could use another thread with the browser to accomplish this. And saving the necessary data to a resource / global variable, then using this data in the new thread, whether with the browser or whatever needs to be done.
