Exactly what i needed. Thank you.

OMG! Where have you been all my life!!! Wish I found you sooner. Major productivity enhancer. Now I can finish working on the left tab w/o getting distracted by new tabs I do not yet want to jump to to the right. TY for creating this add-on! Works perfectly for me thus far.

Works great.

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

It works. But it very annoying, because if you already have a lot of tabs open, and when I open a link in new tab, all tab panel rotates to the left.

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.

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!
