I tried increasing the value of browser.sessionstore.max_tabs_undo, but "More items" still appears in the tab context menu.
I removed the add-on once and added it again, but no change.

A needed extension that works to not simply reopen closed tabs, but to provide a list of ones to chose and reopen.

That is, once you right click on the toolbar icon, hit Manage... then Options and deselect "do not show a list..." which I think should not be checked by default, or at least it should be mentioned as being so.

Thanks much though and I thank God for those as you which provide such needed extensions. Note that I use it along with the Izheil Fix for multirow duplicated buttons on titlebar

Is there a way to redirect the hotkey (ctrl-shift-T) to this addon?
E.g. somewhere in about:config

very nice

One of those "Must-have" addons.

You can just use ctrl+shift+t

è perfetto

Simple, but time saving button. Dont know, why Mozilla is so stupid, not having this as an standard option.
