I've settled on AllTabsHelper https://addons.mozilla.org/en-US/firefox/addon/all-tabs-help...

Not as full featured as some of the others but does what I need.

I wish any of the tab managers would allow me to sort by domain, as it is I've installed a second add on just to do this https://addons.mozilla.org/en-US/firefox/addon/order-tabs-by...

As someone who keeps tabs open forever (as better bookmarks), resulting in tens of windows with each tens of tabs, I finally settled on Tab Session Manager [1] which allows me to "stash" these Windows and restore them later.

It seems this add-on manages and AllTabsHelper open tabs only and does not have a separate session manger (the one built into Firefox is a joke, sadly).
