Exactly what i needed. Thank you.

Works great.

activate the right tab first，and turn to the left tab

None of these add-ons works without activating the right tab when the active tab is closed. Also you can see the change from the right to the left tab at almost every close of the active tab.

非常好用插件，已经找了好久了。

It activates the left tab on close! ¯\_(ツ)_/¯ Who knew.

But yeah, does as advertised, no nonsense about it.

Only been using for a few hours, but its working great! I've been looking for this function since Tab Mix Plus went away. I tried another add-on but it didn't work reliably, this does! I would prefer that it open the last focused tab, it doesn't. But this is better than the default of opening the tab to the right of the one you close!
