You moved a warmed-up account into an anti-detect browser, and it asks for the password again? The problem is almost always the format: the extension exported JSON, the tool expects cookies.txt, or the other way around. A cookie converter fixes this in a minute: paste the file into the cookie converter<\/a>, pick the target format, import into the profile. Below are both formats, the full workflow, and the errors that kill sessions.<\/p>\n\n\n\n\n\n\n\n

Cookie formats: Netscape cookies.txt vs JSON<\/h2>\n\n\n\n

Netscape cookies.txt is a plain-text file where each cookie takes one line of seven tab-separated fields. JSON is the export format of the Cookie-Editor and EditThisCookie extensions, and of automation frameworks like Puppeteer and Playwright.<\/p>\n\n\n\n

Lou Montulli invented the HTTP cookie at Netscape in June 1994. The browser is long dead, but its file format survived as the de facto interchange standard: curl, wget, yt-dlp and virtually every anti-detect browser read it.<\/p>\n\n\n\n

Parameter<\/th>Netscape cookies.txt<\/th>JSON (Cookie-Editor)<\/th>JSON (Puppeteer \/ Playwright)<\/th><\/tr><\/thead>
Layout<\/td>one line per cookie, 7 tab-separated fields<\/td>array of name, value, domain objects<\/td>same array, expires in seconds<\/td><\/tr>

Used by<\/td>curl, wget, yt-dlp, anti-detect browsers<\/td>export extensions<\/td>automation scripts<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The seven Netscape fields are domain, subdomain flag, path, secure flag, expiry in Unix time, cookie name and cookie value.<\/p>\n\n\n\n

How to export cookies from a browser<\/h2>\n\n\n\n

Cookie-Editor<\/a> is the fastest way, three clicks total.<\/p>\n\n\n\n

    \n
  1. Install Cookie-Editor from the Chrome Web Store.<\/li>\n\n\n\n
  2. Open the site where the account is already logged in.<\/li>\n\n\n\n
  3. Click the extension icon, then Export and Export as JSON.<\/li>\n\n\n\n
  4. Save the output as a .json file.<\/li>\n<\/ol>\n\n\n\n

    Need Netscape right away, no conversion? Install Get cookies.txt LOCALLY<\/a>: its Export button produces a ready cookies.txt file.<\/p>\n\n\n\n

    Converting Netscape to JSON<\/h2>\n\n\n\n

    Open the Accovod cookie converter<\/a>, paste your data, pick the direction, copy the result. It works like Netscape to JSON for profile imports and extensions. The converter handles all cookies problems automatically: restores the header, fixes separators, etc.<\/p>\n\n\n\n

    Importing cookies into an Accovod profile<\/h2>\n\n\n\n

    The cookies are ready, now the transfer:<\/p>\n\n\n\n

      \n
    1. Create a profile in Accovod and attach a proxy. One profile means one IP, and the proxy country must match the country the cookies were issued in.<\/li>\n\n\n\n
    2. Open the profile settings, find cookie import and paste the JSON content.<\/li>\n\n\n\n
    3. Launch the profile and open the site. A live session opens the account without a login prompt.<\/li>\n<\/ol>\n\n\n\n

      Cookies alone do not save an account<\/h2>\n\n\n\n

      The common belief is that imported cookies hold the account by themselves. In reality the server validates the session against the environment: IP, fingerprint, timezone. Typical scenario: cookies pulled from a European IP, pasted into a profile with an Asian proxy. The site sees a familiar token on an unfamiliar device and resets the session or pushes the account into re-verification. For an affiliate team that is a warmed-up account lost: weeks of warming and hundreds of dollars in spend budget.<\/p>\n\n\n\n

      So move cookies together with the environment: same IP country, same timezone, same language, a close fingerprint across canvas, WebGL and fonts. Cookies lower the chance of accounts getting linked; they do not guarantee anonymity.<\/p>\n\n\n\n

      Bottom line<\/h2>\n\n\n\n

      A cookie converter fixes the format, not the environment: the converter takes a minute, the environment you configure before the import. The converter at accovod.com\/cookieConverter\/<\/a> is free and needs no sign-up.<\/p>\n\n\n\n

      FAQ<\/h2>\n\n\n\n

      Can I transfer cookies between browsers?<\/strong>
      Yes, this is standard practice. Export cookies from Chrome or Firefox with Cookie-Editor (JSON) or Get cookies.txt LOCALLY (Netscape), then import the file into the target browser or anti-detect profile. The environment must match: same IP region and a similar fingerprint. Otherwise the site can reset the session as suspicious.<\/p>\n\n\n\n

      Do cookies work with curl, wget and Puppeteer?<\/strong>
      Netscape cookies.txt works natively with curl (-b cookies.txt<\/code>), wget (--load-cookies<\/code>) and yt-dlp (--cookies<\/code>). Puppeteer and Playwright take JSON via the setCookie method, with expires in Unix seconds. Convert between the two depending on the tool: command-line utilities want Netscape, automation frameworks want JSON.<\/p>\n\n\n\n

      What is the difference between persistent and session cookies?<\/strong>
      A persistent cookie carries an expiration date and survives browser restarts on disk. A session cookie has no expiration date, lives in memory and dies when the browser closes. In a Netscape file, persistent cookies show a Unix timestamp in the expiry field while session cookies show 0. In Cookie-Editor JSON, the session field is true or false.<\/p>\n\n\n\n

      Are online cookie converters safe?<\/strong>
      Cookies are full access to your account, so process them only in tools you trust.<\/p>\n","protected":false},"excerpt":{"rendered":"
