+1. Also have not been able to launch Antigravity browser from devcontainers.

In my case, the button works, but then the agent is not able to connect to the browser, as if the extension was not installed. Is there an update on this?

Same to me. The launcher button does nothing and when the agent tries to launch it, it just fails.
