Playwright's Firefox version matches the recent Firefox Stable build. So if you are part of the organization that uses such policies, it is easiest to use bundled Chromium for your local testing, you can still opt into stable channels on the bots that are typically free of such restrictions. Google Chrome and Microsoft Edge respect enterprise policies, which include limitations to the capabilities, network proxy, mandatory extensions that stand in the way of testing. If your site relies on this kind of codecs (which is rarely the case), you will also want to use the official channel. Chromium does not have all the codecs that Google Chrome or Microsoft Edge are bundling due to various licensing considerations and agreements. Media codecs Īnother reason for testing using official binaries is to test functionality related to media codecs. In this case, you can opt into one of the stable channels, 'chrome' or 'msedge'. Having said that, testing policies often require regression testing to be performed against the current publicly available browsers. You catch breakage early and have a lot of time to fix it before the official Chrome update. Since Playwright is ahead of Stable channels for the browsers, it gives peace of mind that the upcoming Google Chrome or Microsoft Edge releases won't break your site.

Since the Chromium project is ahead of the branded browsers, when the world is on Google Chrome N, Playwright already supports Chromium N+1 that will be released in Google Chrome and Microsoft Edge a few weeks later.
