Agent skill fromfeder-cr/invisible_playwright_mcp
What the invisible_playwright_mcp browser server needs on this machine - the patched Firefox it drives, which the server downloads on its own the first time it runs. Use when browser_open answers that the engine is downloading or that its download failed, or right after installing the plugin.

1The server runs with `uvx invisible-playwright-mcp` and needs its browser engine on this machine once, about a quarter of a gigabyte. It downloads it on its own when it starts; while that is in flight, `browser_open` answers with how far the download is instead of opening a browser, and asking again a minute later is all that is needed.23To do the download ahead of time, or again after it failed, in a terminal where the user can watch it, run the block for the user's system:45Windows, in PowerShell:67```powershell8powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"9$env:Path = "$env:USERPROFILE\.local\bin;$env:Path"10uvx invisible-playwright fetch11```1213Linux:1415```bash16curl -LsSf https://astral.sh/uv/install.sh | sh17source $HOME/.local/bin/env18uvx invisible-playwright fetch19```2021Nothing else to configure: no account, no key.
