Updating from old Firefox, great replacement for the old tab groups addon,

Quick question - in the old add on when restoring tabs it would restore the tab including its history (the previous & newer webpages loaded by each tab), is that still the case ?

Also, encountered an issue/bug where the addon reorganises the order the tabs are shown from the last time you shut down pc to when booting it the next day - sometimes moving them to a different group (so far this only happens on tabs on the same webpage - the homepage - google )
