It works sometimes, but it’s too inconsistent for my needs.
So I’ll keep waiting for an update to TMP.

Very much would do what I was looking for - unfortunately I have to agree with the previous comment that it works very inconsistently.

There are some cases where it works as expected, but especially for tab activation after closing a tab it is really un-predictable where it jumps to ... especially if you have been changing tabs in between.

In some cases also opening the tab (I have set it to right) does not work but opens at the end ...

I hope that this will be updated and improved as I could not find any other add-on providing this functionality (still hoping for TabPlus one day :-) ).

PS: I do not know / understand what the author wants to indictate with those lines:
btw:
about:config -> browser.tabs.insertRelatedAfterCurrent -> true
about:config -> browser.tabs.selectOwnerOnClose -> true
Would that indicate that this setting is needed for the add-on to work correctly (it does not), or are those settings changed by the add-on? Some more information might be helpful to improve that add-on ....

PS: Unfortunately the author does not seem to respond to the issues and there has been no update for adressing them ...

This extension covers the main TabMixPlus feature which I lost in 57+, but works inconsistently.

Opening new tabs to the right side works great, but setting "left tab" or "right tab" doesn't work consistently at all. It's fine if I close a new tab right after opening, but if switching to other tabs and then back, closing will often select the tab to the right.

On a side note, *where is the source code?* The extension page says that this is licensed under the GPL v3, which mandates source code distribution, but I can't find a link to it anywhere.

It isn't working as it should most of the cases... I have the setting to focus the left tab after closing a tab, but it's inconsistent. Sometimes it "moves" to the left, but most of the times it "moves" to the right..

I miss Tab Mix Plus less and less. Thank you!

And here is how to always open bookmarks in new tabs:

I set "after close change to: left". It doesn't work. Goes to right, last, source, sometimes left, I don't know it's not consistent. I miss tabmixplus :(

This was what I was looking for to replace Tab Mix Plus. However, it doesn't do enough. TMP was far more robust.

this tool save me. thanks a lot

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!

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!

Pretty good so far, but the "After close, change to" setting doesn't consistently work for the "left tab" option. It works sometimes, but mostly it either just goes back to the default right tab action or randomly goes to the last tab.

when opening a bookmark, the new tab will firstly appear as the last tab, then jumps to the right side of the current tab, witch makes the visual effects not very pleasing

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.
