    // ==UserScript==
    // @name Fix AliExpress spam unsubscribe
    // @description AliExpress has unsubscribe links in their emails but some them are broken because AliExpress doesn't handle this email spam type. This userscript fixes it by adding support for any email spam type.

    // !!!IMPORTANT NOTE!!! You need to enable instant inject mode in the TamperMonkey settings or this script won't work. Here is how to do that:
