 | `QUARTO_CHROMIUM_HEADLESS_MODE` | Used for adaption of the `--headless` mode used with `QUARTO_CHROMIUM` binary. Set to `"none"` for `--headless` , or to `"old"` or `"new"` to pass as argument, e.g. `--headless=<QUARTO_CHROMIUM_HEADLESS_MODE>` . Quarto 1.6 sets `"old"` as default, which works from Chrome 112 to 131. Starting Quarto 1.7.13, `"none"` is the default as [Chrome 132 removed old headless mode](https://developer.chrome.com/blog/removing-headless-old-from-chrome). |
