This is exactly what I was looking for. Although it has a lot of options - the crucial is "Last accessed tab" on close. And it comes preselected by default - no need to tune up anything. Neat!

P.S. Works well with Tree Style Tab.

这是一个看似简单不起眼但实际上必不可少的的扩展之一！配合鼠标手势，加上自身合理的符合自己习惯的设定可以很大程度上减轻操作疲劳，增加效率浏览体验，虽然很多人不会理解因为它的作用并不那么直观但事实上它就是如此优秀

An excellent add-on, works very well, believe it or not, this add-on just do what IE 11 browser's tab can do which I used a lot. With this add-on Firefox works more convenient.

超級好用，關閉分頁後自動到設定好的分頁去，而且有中文

Great ! Works like a charm with a ton of options to customise to one's liking, thank you

It was hard for me, to find out how it works. It would have been easier, it the column "relation" were on the left position und the column "Positon" were right of it. So I would have known, that Relation is the main criteria.
If you add some examples to the description, the configuration would be much easier, to understand.
With a better description I would have rated 5 stars.

一直在找关闭后打开左侧标签页，好不容易找到了，作者应该优化下插件的关键词，不容易被搜到

A must have add-on! I don't know why this feature + "New tab" in the context menu + "open new tab" to the right of selected tab doesn't exist by default in Firefox! Thank you to the developer!

Great. But is there a documentation??

太赞了. tabMix 不能用后一直在找类似扩展, 本来都已经死心了, 今天无意间找到这个, 太惊喜了.
必须五星好评

The only tab-closing add-on I know that provides options and actually works!

Супер дополнение! Лучше чем TST Focus Preceding Tab On Close, пользовался ним ранее. В этом дополнении нет бага с кратким переходом на правую вкладку и только потом на левую, сразу переходит куда нужно. + отличная идея - сначала переходить на предыдущую вкладку потом на левую и когда закончились на правую. Огромная благодарность автору, удачи Вам!

This addon did exactly what I expected! thank you!
非常感謝!這套件太神了!

非常好的扩展，但是稍有不足，是否能有如下操作：
1 当前浏览器标签页A
2 点击标签页A里的任何链接a1，a2，a3....并且是按顺序紧靠A右边后台打开，此时A（前台），a1.a2.a3都是后台未读状态（子标签页）。
3 切换至a1（前台）点击里面任何相同或不同域名的链接aa1前台打开浏览（孙标签页或其他网站），此时a2.a3仍旧是后台未读状态。
4 浏览完aa1（孙标签页或其他网站）后关闭该标签页或其他网站后自动切换至a1（子标签页），此时a2.a3仍旧是后台未读状态。
5 关闭a1（子标签页）后自动切换至a2（子标签页），此时a3仍旧是后台未读状态。
6 如上类似操作浏览完全部a2，a3，a4...关闭后自动切换至父标签页A。
上述的操作只有旧版的tab_utilities_fixed能够做到(1 关闭选取未读亲属标签页，2 上次选取的标签页）。希望能更加完善。谢谢！
