#326) #320 Issue: It would be very useful to have the ability to simulate offline network conditions directly through the MCP emulate_network command, similar to how it's possible in DevTools. Currently, the command doesn’t support an Offline state, which limits testing for PWA and offline-first web applications. Adding this option would make it easier to automate and validate offline behavior through MCP scripts or tools that rely on this API. Solution - Add 'Offline' option to throttlingOptions for simulating offline network conditions - Update emulate_network tool to handle offline mode with proper network conditions - Update documentation to include offline option and usage instructions - Add test coverage for offline network emulation functionality - Enable testing of PWA and offline-first web applications through MCP
