# Q: I am having trouble installing / running Puppeteer in my test environment. This means that Puppeteer does not support HTTP Live Streaming (HLS).

Since Puppeteer (in all configurations) controls a desktop version of Chromium/Chrome, features that are only supported by the mobile version of Chrome are not supported.

You should only use this configuration if you need an official release of Chrome that supports these media formats.)

(However, it is possible to force Puppeteer to use a separately-installed version Chrome instead of Chromium via the executablePath option to puppeteer.launch. This means that Puppeteer does not support licensed formats such as AAC or H.264. Puppeteer is bundled with Chromium - not Chrome - and so by default, it inherits all of Chromium's media-related limitations.(For example, video playback/screenshots is likely to fail.) There are two reasons for this: You may find that Puppeteer does not behave as expected when controlling pages that incorporate audio and video. The Puppeteer team needs input from users to stabilize Firefox support and to bring missing APIs to our attention.įrom Puppeteer v2.1.0 onwards you can specify puppeteer.launch( ) # Q: What features does Puppeteer not support?

The ongoing collaboration with Mozilla aims to support common end-to-end testing use cases, for which developers expect cross-browser coverage.

Official Firefox support is currently experimental. # Q: What is the status of cross-browser support? The Chrome DevTools team maintains the library, but we'd love your help and expertise on the project! See Contributing.
