When I open more tabs than fit in the tab bar (horizontally), tabs move out of view on the right with no UI to reach them. I must be missing something.
In this screenshot I have more tabs open than fit horizontally in the bar, and to reach those, I have to close visible tabs.

Below is a screenshot of how firefox handles this. A button appears with an arrow to the right, which, when clicked moves to the right.

I expect some UI element to move the tab bar, like the arrow in Firefox.
