<li>We support installing and running Firefox, Chrome and Chromium. The <code>latest</code>, <code>beta</code>, <code>dev</code>, <code>canary</code>, <code>stable</code> keywords are only supported for the install command. For the <code>launch</code> command you need to specify an exact build ID. The build ID is provided by the <code>install</code> command (see <code>npx @puppeteer/browsers install --help</code> for the format).</li>
<li>Launching the system browsers is only possible for Chrome/Chromium.</li>
