Hey there, please check the browser pool docs: https://github.com/apify/browser-pool#manipulating-playwright-context-using-pageoptions-or-launchoptions + https://crawlee.dev/api/playwright-crawler/interface/PlaywrightLaunchContext#launchOptions

I Already tried, but it doesn't set the user agent in the browser, just the header.

what do you mean by that? If you see it the headers - it means it's set. If you see this user-agent in browser request headers - it means it's set

My crawlee is printing this agent

i want this 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.102 Safari/537.36 Edg/104.0.1293.63'

Got it. This should work:

const crawler = new PlaywrightCrawler({
    launchContext: {
        launchOptions: {
            userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.102 Safari/537.36 Edg/104.0.1293.63'
        }
    },
...

const crawler = new PlaywrightCrawler({
    launchContext: {
        launchOptions: {
            userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.102 Safari/537.36 Edg/104.0.1293.63'
        }
    },
...

and maybe also switch off fingerprints (but not necessary): browserPoolOptions: { useFingerprints: false }, as another crawler option
