Works as it is designed but I would like an option to not activate the tab to the left when closing current tab.

You saved my life

Works for me, many thanks. How this isn't an option in default browser just boggles my mind.

Simple and easy to use. 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.

Thank you. Does exactly what I need it to do, and I appreciate it for all the same reasons that led to its creation.

非常好，简单好用，满足使用要求！其他类似的扩展总是有些BUG，这个没有发现问题！

Good!

Great add-on, does what it claims to do!
One drawback I notice when used in conjunction with Firefox' "Restore tabs from previous session" option enabled. See https://github.com/czukowski/tab-control-extension/issues/1

Open right Close left タブを右隣に開いて閉めたら左に simple and great!!

Working properly on firefox 61

Does exactly what it says to be, in a perfect and smooth manner.
I had tried the extension 'Open tab next to current' but it wasn't as smooth (tab opening was putting new tab right to the current one, but was then transferring this new tab at first place in list of tabs.).

Thank you very much.

Really nice addon but the addon does actually focus right tab then changes focus to left tab and this causes to load tabs that I dont want to get loaded. Can you fix that?

This is exactly the addon I wanted! I had tried all the other alternatives listed by the developer (as well as Tab Position Options) before, but none of them functioned perfectly the way this one does! Consistent behavior even with other new tab opening addons that I have, I love it! Thanks, czukowski!
