333ywb：我是绿色便携版本，不能同一版本开两个，也懒的折腾同一版本开两个。所以装了68和69回到原帖

kidzgy：不会，67可以开两个了，除非你安装了合并窗口的扩展回到原帖

kidzgy：不会，67可以开两个了，除非你安装了合并窗口的扩展回到原帖

333ywb：我这里同一个版本只能开一个，开不了两个。回到原帖

kidzgy：你试试运行两次FIREFOX.EXE回到原帖

333ywb：我都是在一个程序中用，没有多开用过回到原帖

kidzgy：我所反馈的是你的一模一样的，用是可以正常用，只运行一个窗口的时候是没有问题，但是当第二次运行程序，有了第二个窗口后，撤销图标就显示不出来了。回到原帖

333ywb：这个可以用，我的67版本正常使用
