-> Tab Open/Close Control
Mince... ça n'a fonctionné qu'une seule fois à l'installation...

Je l'avais installé pour, lorsque que je ferme un Tab/onglet, FF revenienne au Tab de gauche et non plus à celui de droite.

Du coup, je désinstalle

Open tab on right works, but close tab go back to left is not working on FF83, instead it just going back to last active tab after closing.

Use this addon instead... "Activate Left Tab On Close"

open tab on right works, but close tab go back to left is not working on FF77.01, instead it just going back to last active tab after closing.

Doesn't work for "Closing a tab" - still always goes to the last active tab.

Can confirm this: After close the tab often leads to a different tab but not to the left one! I'm sorry :(

After close the tab often leads to a different tab but not to the left one! I'm sorry :(

After close change to "LEFT TAB" often leads to a different tab but NOT to the left one! :(

変な位置にタブが飛ぶことが多い

It works as expected, but after a delay: when I close a tab, at first it skips to the tab Firefox would have switched to by default and after a moment to the one determined by the add-on setting. It's confusing.

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

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 :(
