Just works.

sehr gutes addon, traurig das man für so einen funktion ein addon braucht, eigentlich sollte sowas in firefox integriert sein. firefox wird immer schlechter von update zu update.

Great extension, as good as it could be!

Works on 57.0.1 version.

If I close a tab, and regret doing so, and immediately click on the new icon, the vanquished tab immediately reappears, IN THE SAME LOCATION! Also, the icon is large enough and explicit enough and looks good, as well. My pleasure is commensurate with that of porcine mammals immersed in feces!

终于找到了一个可以恢复关闭标签页的插件了！

Excellent for me, just need a solution for dark theme...
I go to https://github.com/M-Reimer/undoclosetab/issues/18

Works exactly as described and does what I want. Perfect!

Открыть последнюю закрытую вкладку — одна из самых необходимых функций для торопыг вроде меня, впопыхах закрывающих среди нескольких десятков вкладок не ту, которую на самом деле хотел закрыть. Эх, скорее бы к нам вернулся комбайн по имени Tab Mix Plus...

good job

升级到FF57，找到了替代的撤销关闭按钮，好评。

simple yet effective, thank you for this.

My favourite solution to re-open closed tabs, with an icon that fits in seamlessly.

The best add-on! I cannot use firefox without it

Left click the button to restore the last tab, right click to choose previous tabs from the context menu. Just what I needed!

Also great monochrome icon but it would be nice to have some color customization options.
