/**
 * BrowserFetcher can download and manage different versions of Chromium and Firefox.
 *
 * @remarks
 * BrowserFetcher operates on revision strings that specify a precise version of Chromium, e.g. `"533271"`. Revision strings can be obtained from {@link http://omahaproxy.appspot.com/ | omahaproxy.appspot.com}.
 * In the Firefox case, BrowserFetcher downloads Firefox Nightly and
 * operates on version numbers such as `"75"`.
 *
 * @example
 * An example of using BrowserFetcher to download a specific version of Chromium
 * and running Puppeteer against it:
 *
 * ```ts
 * const browserFetcher = puppeteer.createBrowserFetcher();
 * const revisionInfo = await browserFetcher.download('533271');
 * const browser = await puppeteer.launch({
 *   executablePath: revisionInfo.executablePath,
 * });
 * ```
 *
 * **NOTE** BrowserFetcher is not designed to work concurrently with other
 * instances of BrowserFetcher that share the same downloads directory.
