Good afternoon. We do not collect information when you visit other sites. AliExpress has several domains and they keep appearing - subdomains *.aliexpress.com , aliexpress.us, aliexpress.ru, tmall.ru. To integrate AliHelper on all AliExpress domains easily and without bothering the user, we use this permisson. You can see in manifest.json that AliHelper integrates only on AliExpress sites. We are very sad that you rate our extension with 1 star for this reason.
