Having trouble importing cookies? Don’t worry – here are the most common issues, why they happen, and how to fix them in no time!

Issue 1: error “File cookies must be in JSON or Netscape formats. Please try again.”

This error happens because the format checker doesn’t support nested JSON values like "partitionKey":{"topLevelSite":"https://google.com"}.

Here's how to fix it:

Remove all occurrences of the "partitionKey" block from your JSON file like on the screenshot below, then save and try to import the file again.

Issue 2: only some cookies import successfully

When you import cookies, only some make it through – frustrating, right? It’s usually because a few don’t meet the right format, or there’s a small hiccup during the process.

Here's how to fix it:

1. Find the missing cookies: see which ones didn’t make it through

2. Retry importing: only re-import the missing cookies to save time

Issue 3: cookie import freezes or fails

If the process freezes, or you see a “Failed to import cookies” error, don’t panic! This might happen if your Windows username has non-Latin characters (like Cyrillic) or if the cookie file format isn’t supported.

Here's how to fix it:

1. Try manual paste: copy the cookies as plain text and paste them directly into the cookie import window
2. Check your username (Windows only): make sure it only uses Latin characters (for example, no special characters or Cyrillic)

Nothing helps?
