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.

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.
