Treat it as cookie metadata—not as a rule that decides which matching cookie is sent or guarantees that a cookie is kept. Chrome DevTools marks the Priority attribute deprecated. For new code, set cookies through Browser.setCookie() or BrowserContext.setCookie(); Page.setCookie() is obsolete.
What does cookie priority mean in Puppeteer?
Puppeteer exposes priority as an optional cookie property, and its API documentation says it is supported only in Chrome. Chrome DevTools lists three values: Low, Medium, and High, with Medium as the default. DevTools also labels the Priority attribute deprecated. See Puppeteer’s CookieParam and CookieData references and Chrome DevTools’ cookie documentation.

The word “priority” can sound like request ordering. The documented field does not establish which of two cookies wins when both are eligible for a request, nor does the documentation promise that a high-priority cookie will be retained. Do not use it as a substitute for correct cookie scope or sending attributes.

Use the browser or browser context that owns the cookie store needed by your navigation or request. A browser context has isolated storage, so setting a cookie in one context does not make it available in another. Puppeteer documents both browser- and context-level cookie methods; its cookie guide covers setting, reading, and deleting cookies. See Puppeteer’s cookie guide and the obsolete Page.setCookie() reference.

Set a cookie on a browser context
This example launches Chrome, sets a high-priority cookie in the default browser context, navigates to the relevant site, reads the cookie store, and closes the browser. Replace the example domain and value with ones appropriate to your test.
import puppeteer from 'puppeteer';
const browser = await puppeteer.launch({
// Use a Chrome executable when your environment does not default to Chrome.
// executablePath: '/path/to/chrome',
});
try {
const context = browser.defaultBrowserContext();
await context.setCookie({
name: 'session',
value: 'example-value',
domain: 'example.com',
path: '/',
secure: true,
httpOnly: true,
sameSite: 'Lax',
priority: 'High',
});
const page = await context.newPage();
await page.goto('https://example.com/', { waitUntil: 'domcontentloaded' });
console.log(await context.cookies('https://example.com/'));
} finally {
await browser.close();
}The example assumes Puppeteer and a compatible Chrome installation are available in the runtime. If using a non-default context, call setCookie() on that same context, then navigate with a page created from it.

Use the browser-level API instead
If you want to set cookies for the browser’s default context, Browser.setCookie() is also a current option:

});For an isolated test, prefer the explicit context API so it is clear which cookie store receives the cookie. The browser- and context-level APIs do not change the meaning of the cookie’s scope or sending attributes.

Which cookie attributes control whether a cookie applies?
Priority is separate from the cookie properties that define its scope, transport, lifetime, script visibility, or partition. Set those properties according to the behavior you need:
| Attribute | What it controls |
|---|---|
domain and path |
The hosts and URL paths within scope. |
secure |
Whether the cookie is limited to secure connections. |
sameSite |
Whether the cookie is eligible in same-site or cross-site contexts. |
expires |
Persistent expiration. If omitted, the cookie is a session cookie. |
httpOnly |
Whether JavaScript can access the cookie. |
partitionKey |
In Chrome, the top-level-site context associated with a partitioned cookie. |
priority |
Optional priority metadata; Puppeteer’s API documentation says it is Chrome-only. DevTools lists Low, Medium (default), and High, and marks the attribute deprecated. |
For Chrome’s documented behavior, an omitted SameSite value is treated as Lax; cross-site cookies must specify SameSite=None and Secure. That policy is independent of Priority. Consult the Chromium SameSite FAQ for that behavior.

Does priority decide which cookie Puppeteer sends?
No such rule is established by the cited Puppeteer and Chrome documentation. Whether a cookie is eligible for a request depends on its scope and sending conditions—such as domain, path, Secure, and SameSite—not on treating priority as a matching-cookie tie-breaker. Likewise, the documentation reviewed does not establish a complete current eviction algorithm or guarantee that High prevents eviction. If correctness depends on a cookie being present, verify it in the intended context rather than relying on its priority value.
Common problems and fixes
- The cookie is missing after navigation: Confirm the page was created in the context where you set the cookie. Contexts have isolated storage. Check that the target URL matches the cookie’s domain and path, and that Secure and SameSite conditions allow sending.
- The cookie is rejected or behaves unexpectedly on a cross-site request: Check SameSite separately from Priority. In Chrome’s documented behavior, cross-site cookies require
SameSite=NoneandSecure. - The priority field has no effect in another browser: Puppeteer’s API reference documents
priorityas Chrome-only. Do not assume another browser implements the field. - A tutorial reports that
page.setCookie()is obsolete: It is. Usebrowser.setCookie()orcontext.setCookie()instead. - A high-priority cookie is still missing: High is not a documented guarantee of retention or request eligibility. Inspect the cookie’s other attributes and the context, and do not infer a complete eviction policy from the priority label.
Or skip the browser setup
If the goal is to capture a website rather than test cookie behavior in Puppeteer, ScreenshotNeo provides a one-request screenshot API. It accepts consent banners like a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each step can be turned off. Bot checks, blank pages, failed loads, timeouts, and cache hits are not billed. Its MCP server gives AI agents screenshot tools, and the API also supports PDF capture.
