Unable to download both chromium and firefox

[LarsDenBakker]

It's possible to influence the postinstall script by setting the puppeteer product environment variable.

However this variable accepts only a single value, while I'd like to use puppeteer to run both chromium and firefox in a single project.

PUPPETEER_PRODUCT is already used for running puppeteer, so it makes sense that it's a single value only. Could we perhaps add a separate environment variable to configure just the installation behavior, which allows setting multiple products? For example PUPPETEER_INSTALL=chrome,firefox.

This will be possible once puppeteer-firefox is no longer experimental. cc @mjzffr

Why is this reliant on the experimental status? From what I can tell, this is mostly a change that's needed in the installation script.

[mathiasbynens]

Once puppeteer-firefox is no longer experimental, npm i puppeteer will install both browsers.

@mjzffr @mathiasbynens Thanks for the info. Do we have any rough estimates or goals when it will no longer be experimental? We want to ship (experimental) firefox support for puppeteer in web test runner. I'm happy to create a PR to create a solution for the short term.

@LarsDenBakker What would your short-term solution be?

@mjzffr This issue has been open quite a while but in the event you haven't found a solution, this is what I'm doing in package.json.

"prepare": "node -e \"require('child_process').execSync('cross-env PUPPETEER_PRODUCT=firefox node node_modules/puppeteer/install.js');\""

@OrKoN I would leave this up to you to decide. Not sure if issue #6371 should really block here.

There is already a CLI interface to download other browsers:

npx puppeteer browsers install firefox

We also want to update the configuration to allow configuring browsers for download (and probably corresponding env variables) (cc @Lightning00Blade)
