// @description        Try to make userscripts work on non-tempermonkey environments(e.g. X Browser, Via Browser, etc.) as well. Attention: All data that are expected to be saved in browser storage will actually NOT be saved, that means, everytime the userscript executes will act as this is the first time.
// @description:zh     尝试使其他用户脚本适配没有油猴支持的运行环境（如：X浏览器，via浏览器等等）。注意：所有的脚本存储在本地的数据都将不会被真正储存，而是会随着浏览器页面的关闭而被丢弃，也就是说，每次脚本运行时，都将如同第一次运行一样。
