After visiting aliexpress.ru it can mess up the locale settings on aliexpress.com - "com" will redirect to "ru" ("gatewayAdapt=glo2rus") and reset the location/language/currency settings. This script pins locale settings cookie, sets currency to USD, language to EN, country to UA, and redirects "ru" to "com". Please clear cookies on all "aliexpress" domains before using this userscript.
Works fine. Easy to adapt for other regions (BY in my case).
