One of the cool Google Chrome browser features is the ability to pin tabs in the browser by default.
Pinned tabs are shifted to the left side of the tab bar where their tab will be changed to just show the favicon for the web site in question. Thanks to the Pin Tab add-on for Firefox, you can bring that functionality to your favorite browser.
Another neat feature of this Firefox add-on is when you type something in the address bar, or select a result in the address bar while a pinned tab is selected, the address you selected will open in a new tab – leaving your pinned tab alone.
How do you pin a tab?
You can also pin a tab by dragging it to the left of already pinned tabs.
