# abstractBrowserPlugin<!-- --> \<Library, LibraryOptions, LaunchResult, NewPageOptions, NewPageResult>

The `BrowserPlugin` serves two purposes. First, it is the base class that specialized controllers like `PuppeteerPlugin` or `PlaywrightPlugin` extend. Second, it allows the user to configure the automation libraries and feed them to [BrowserPool](https://crawlee.dev/js/api/browser-pool/class/BrowserPool.md) for use.
