Cookie locking doesn't work (tested in Firefox v110). AliExpress can still overwrite the locale.

Needs work. I tried this extension (2021-05-17) on Firefox 88 on Linux and the extension pop-up window keeps growing longer and longer until the green check-mark at the bottom extends beyond the bottom of the screen and is no longer accessible. I consider this a serious defect and have, therefore, removed this extension from Firefox.
