GitHub Copilot in VS Code — June 2026: Browser Tools GA, Parallel Sessions, 1M Context
GitHub
GitHub's June 2026 VS Code Copilot release (published to changelog July 8) ships: agentic browser tools now generally available (navigate live web apps, inspect DOM, capture screenshots, proxy HTTP(S)); parallel agent tasks in separate windows; multiple chats per session; 1M-token context windows; total session cost tracking and per-subagent credit inspection; and AI-generated PR titles and descriptions.
Why it matters
Making browser tools generally available closes the gap between Copilot agents and browser-native testing/QA workflows. Parallel sessions and granular cost visibility address two of the most common friction points for teams running long-running agents.
Importance: 3/5
Major VS Code Copilot feature bundle: browser tools GA, 1M context, and parallel sessions represent significant capability expansion.
