# BrowserFetcher class
BrowserFetcher can download and manage different versions of Chromium and Firefox.
#### Signature:
```typescript
export declare class BrowserFetcher
```
## Remarks
BrowserFetcher is not designed to work concurrently with other instances of BrowserFetcher that share the same downloads directory.
## Example
An example of using BrowserFetcher to download a specific version of Chromium and running Puppeteer against it:
```ts
const browserFetcher = new BrowserFetcher({path: 'path/to/download/folder'});
const revisionInfo = await browserFetcher.download('533271');
const browser = await puppeteer.launch({
executablePath: revisionInfo.executablePath,
});
```
