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.

-> 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 FF77.01, instead it just going back to last active tab after closing.

To open new tab as First Tab doesn't seem to work, it opens as Last Tab, same behaviour as open as Last Tab. Otherwise most things else seem to work great! I initially wanted the open as First Tab, but will try "open to the Left Side of Active" for a while now, think it will be perfect actually! Firefox version: 76.0.1 (64-bit)

Awesome plugin, very needed! Missed this a long time.

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

nice :)
But when opening new tab all tabs move to the left until the new tab will be at the left border o_O
Is this normal?
How can i change this that only all tabs to the right move only one tab on?
thx

This add-on allows you to place where the new tab (from link) is and return to the position you want. I choose to place new tab before the unread tab and return to its source. It works.

FF60.6 ESR x64 - I needed this addon for 2 things: open new tabs on the right side (instead of at the end) and switch to left side on close (instead of right). The first one works, but sadly the latter is inconsistent and sometimes jumps at random tabs.

EDIT: tested on normal FF66 too. Same problem.
