Depending on your job, you may have to open many browser tabs and some of those you may need to open many a time in a day.
Also, you must be aware, tab opening starts from left and goes on the right side, which means the first tab you open will be placed at the extreme left unless you move it. This is the reason that most people often develops a habit to place their important tabs on the left. However, if you follow this practice daily than Firefox has some better solution for you, which is known as Pin Tab, using which you can lock those tabs which you often use and reduced them to just the size of an icon. This helps you to store your favorites in a confined space.
The process to pin a tab is quite simple. To pin a tab, you just need to right-click on the required tab and select “Pin Tab” option from the drop-down menu. The tab will move to extreme left available tab, with its icon.
You can pin all the apps that you keep open all day. This will anchor all of them on the left and then you can move around the pinned tabs among each other as per requirement.
One of the nicest thing Pin Tab has that the tab loses “X” factor. You just cannot click on it, even by accident. It just goes away once the tab is pinned.
However, you can unpin any tab by recognizing its icon. To unpin a tab just right click on the tab and select Unpin Tab option from the drop-down menu.
So, if you also always wish to keep your favorite tabs opened at the extreme left of your browser then, just pin those tabs.
