not working on 95.0.2

Unfortunately, this doesn't work for the only purpose I downloaded it for: opening new tabs as "first", on the left of the window, before all other tabs.

(The other functions of the add-on seem to work, though, under a cursory test. YMMV.)

This not work when close tab with gesture.

Doesn't work as expected. After closing a tab any other tab can become active despite of the addon settings.

Does not work on Firefox 65 or 66

Doesn't work. I was forced to manually change the settings :(

Simply not working on Linux Ubuntu 18.04 (Bionic), Firefox 61.0.1 (64 bit)

04/07/2018 - Triggers "New tab open at" and "After close, change to" does not work after last update 5 april 2018

04/04/2018 - Very good but If trigger "After close, change to" = "LEFT TAB" then Close tab leads to a Last active tab but not to the Left one. Fix it please.

не переходит на левую вкладку

Despite selecting "New Tab Open at: Last Tab," 9 times out of 10 it (=version 0.0.3--I will keep my eye out for updates) opens new tabs immediately to the right of the current tab instead of as the last tab.

"Activate left after close" doesn't work at all.
"Open new to the right" works unreliably.

Working solution is combination of "Open Tabs Next to Current" and "Select After Closing Current".
Though using 2 extensions to cover basic tabs customization is ridiculous, of course... :(

設定After close, Change to left Tab不起作用.書簽欄一次打開多個分頁.順序會顛倒
Set After close, Change to left Tab does not work. Bookmarks bar opens multiple tabs at once. The order is reversed.

Doesn't seem to work. Set it to open new tabs last but it doesn't.

dont realy work!

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 ...
