About this extension
扩展设置中提供了灵活的黑白名单模式,以满足不同场景下的去重需求。
  • 白名单模式(豁免范围):默认对所有网站开启去重检测,但列表内的域名除外(即:列表中的网站允许重复打开,其他网站全部自动去重)
  • 黑名单模式(生效范围):默认完全不拦截,仅对列表内指定的域名进行去重检测(即:只有列表中的网站会被去重,其他网站允许重复)
  • 规则管理:每行一条规则,支持填写域名(匹配全站)或具体网址(匹配以该地址开头的页面);保存时自动去除空行和重复项

-------------------

扩展特性:
  • 智能去重:自动识别并忽略 URL 中的常见跟踪参数(如 utm_、fbclid 等)和哈希值,确保即使链接携带不同参数也能被精准识别为重复页面
  • 实时响应:在标签页打开、加载、更新或替换时实时监测,零延迟自动关闭重复的新标签页并激活已有的旧标签页
  • 即时生效:更改模式或更新规则列表后,扩展会立即重新扫描当前所有打开的标签页,并严格按照新规则执行清理
  • 微信优化:内置针对微信公众号文章链接的特殊清洗规则,有效解决同一篇文章因分享来源不同导致链接参数差异大而无法去重的问题
  • 启动扫描:浏览器启动时会自动运行一次全量扫描,根据当前规则清理上次会话遗留的重复标签页
