Super!

Thank you for making the new Firefox 57 back to "normal" !

Good Add-on.

You've just saved Firefox 57+ for me. THANK YOU!

One of the two functions from (defunct) Tab Mix Plus that should be native in FF.
- Open new tab at right
- Return to source or last tab on close

Whitout this (and multi-row tabs bar), I will switch to Chromium :((

Thank you

Great! This is what I need!

Finally, I can control where new tabs appear again! And what happens after a tab is closed! Essential for a tab monster like me.

Tab controlling extension is an absolute must for Firefox users that do not like the default behavior. At the time of writing, this extension is the only one that works with Firefox 57. I works great apart from a few minor issues that I'm sure the author will fix soon.

Works pretty fine. I think we should have this functionality with native Firefox. Thanks!
