Roll over the markers below for feature info

No, not this one

This one’s just here to tell you to roll over the other ones, which you should do, instead of rolling over this one, which is also fine, but doesn’t actually give you any info about Firefox.

Tabs on top

Tabs are now located above the Awesome Bar to make it easier to focus on the content of the sites you visit.

App Tabs

Take sites you always keep open — like Web mail — off your tab bar and give them a permanent home in your browser.

New tab

Firefox gets you to your next task faster than ever. Choose from your most recently and frequently visited sites when you open a new tab.

Switch to tab

As you’re opening a new tab, Firefox will check to see if you already have that site open. If you do, you’ll be directed to the existing tab so you don’t open a duplicate.

Firefox menu

All your menu items are now found in a single button for easy access.

Bookmark button

Manage your bookmarks in a single button. Find your favorite links without getting bogged down!

Home button

The home button, now located on the right hand side of the browser, can be easily customized to open the preferred website you want to see as your home page.

Awesome Bar

Get to your favorite sites quickly, even if you don’t remember the URL. Start typing and the Awesome Bar will include possible matches from your browsing history, bookmarked sites and open tabs.

Instant website ID

Want to be extra sure about a site’s legitimacy before you hand over your personal info? Click on its favicon for an instant identity overview.

Customize toolbar

You can adjust the Firefox interface to be exactly the way you like it: re-arrange, organize, add or remove buttons or fields to change your browsing experience however you want.

Add-ons manager

The Add-ons Manager Discover and install add-ons without ever leaving Firefox. Browse ratings, recommendations, descriptions and pictures of the add-ons in action to help you make your selection.


Change the look of your Firefox in a single click with Themes, Firefox’s easy-to-install browser art created by users from around the world (or that you make yourself!).
