When I open/expand a tab group, if the group is located near the end of the tab bar, some of the tabs become partially or completely hidden outside the visible area. I then have to manually use the horizontal scroll arrows to see them.
I would like Firefox to automatically adjust the visible position of the tab bar when opening a group: if the expanded tabs do not fit on the right side, the tab bar should automatically scroll to the left so that all tabs in the opened group are immediately visible without requiring any additional user action.
