Is it possible to scroll the tabs in Safari if there are too many like Firefox? When I open a lot of tabs in safari it shows the first ones normally and all those, which do not fit a grouped into one tab. This is very annoying when switching between tabs that are at the end.

Is it possible to make them scrollable as it is done in Firefox?
If you are running the latest version of Safari, you can pinch in on a trackpad to reveal all of your tabs. You can swipe through this list using two fingers or by clicking on the dots below the previews.
