After moving to the left side, a pinned tab automatically changes to a smaller icon, only showing the favicon of the website. The ability to pin tabs is one of the most useful features in modern browsers that offers an easy way of keeping your favorite websites always available to you on the left side of the tab bar without actually bookmarking them. Fortunately there’s now a quick solution to resolve this issue, thanks to a minuscule extension called PinTabAlt. For instance, one major caveat with the feature is that when you have multiple Firefox windows open and you close one of them that has pinned tabs, all your pinned tabs in the close window are lost, and there is no way to bring them back even if you restart Firefox. However, as useful as it gets, the Pin Tab option of Firefox still has room for improvement. The tab pinning feature was initially introduced in Google Chrome, but after seeing its popularity among Chrome users, Mozilla didn’t waste any time in bringing the functionality to Firefox as well.
