Have you ever lost a tab in Safari? You have like a milli things open, and you end up scrubbing a two-fingered trackpad swirl over the entire tab bar, moving those things around so that you can read their labels, and you still can not track down the Cult of Mac website there. Well, here's good news: you can simply pin this tab to the edge of the tab bar, so you'll never lose it again.
Pin Safari tab
A pinned tab remains at the far left of the Safari tab bar and it also shrinks. While the usual tabs change in size, and display ly a few letters – if that's the case – of their title when you have a lot of otters tabs cluttering the bar, a pinned tab can always be seen. It turns into a small square, with a big letter to help you out. This full badge will always be visible at the end of the row of tabs, and you can pin multiple tabs if you wish.
