Firefox DevTools member here. We are looking into Puppeteer/CDP – what is the product you depend on? If you can't post it here, feel free to email me [nickname] at mozilla org
Not the OP but, I use puppeteer (and headless Chromium) as a PDF rendering service. I'd love to be able to try the same thing with a headless Gecko/Slimer.js type thing. My current build process is a major pain to keep updated (building an Alpine docker image with the right version of Chrome to match the right version of puppeteer with the right version of nodejs) And after all that, it's pretty slow.
Badly worded on my part, but it's my own product. I use Puppeteer to run headless Chrome instances in AWS Lambda to evaluate the network traffic associated with advertising data collection. I have a toolchain built around Puppeteer and CDP, which is in use by customers, so migration isn't a viable option for me.
