There is a "Language" option in the upper right corner of the AliExpress page. Click it and select French. Then wait a little and it will switch to the English version soon.

In fact, the product information on AliExpress is mainly in English, Russian and Portuguese. Of course, this is only the system's active setting. If you want to set languages ​​like Japanese, Chinese, Spanish, etc., you can also use relevant means to achieve similar goals.
