Mozilla Firefox

Add Style: Personas

Make Firefox match your style! Choose from thousands of Personas designed by users around the world, or create one yourself. With a single click you can dress up your browser however you want.

Customize: Add-ons

Many of the most popular add-ons are extensions, little extras you download to add more bells & whistles to Firefox. Compare prices, check the weather, listen to music, update your Facebook profile – all built right into the browser! There are thousands to choose from, but here are a few of our favorites:

Make It Work: Plugins

Plugins are small bits of third-party software built by companies like Adobe Systems or Apple to power videos, animation and games (examples include Flash Player or Quicktime). They can cause browser crashes or pose security risks when they get out of date, so we’ve built an easy tool to help you stay current. Check your plugins.

Adapt Your Interface

The Firefox interface has been designed by a team of experts and tested by a community of millions of users around the world to make sure your browsing is as easy and intuitive as possible.

But, everyone has their own specific needs, and you can always adjust the 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. Learn more.

Stay In Sync

Sync seamlessly connects your desktop and mobile Firefoxes, so you can access your browsing history, passwords, bookmarks and even open tabs no matter which device you use.

Now you can surf the Web on your desktop, get up in the middle of browsing and have your open tabs ready and waiting on your mobile, just as you left them. Your browsing will never be the same! Learn more.
