Is this important? I use Selenium, and have a vague impression that Puppeteer is considered somewhat better, but I have no idea if the difference is enough to really care about. I only use Firefox and don't care about Chrome.

Re: Puppeteer Support for Firefox
#92What are reasons to prefer puppeteer to playwright which supports many browsers? > Cross-browser. Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. https://playwright.dev/
Playwright is shipping patched browsers. They take the open source version of the browser and patch in e.g. CDP support or other things that make automation "better. Playwright does not work with a "normal" Safari for example.
