How to sync Firefox settings between computers

You can use Firefox Sync to synchronize your bookmarks, passwords, settings, history, and tabs with Firefox on other computers. First just set up Firefox Sync on your main computer and then add each of the other computers.

Part 1: Set up Firefox Sync on your main computer

  • At the top of the Firefox window, click on the Firefox button (Tools menu in Windows XP) and then click Options . In the Options window, click on the Sync tab.
  • Click Set Up Firefox Sync

  • Click Create a New Account

  • Enter your email address, create a password and confirm it. Then check "I agree to the Terms of Service and Privacy Policy" and click Next.
  • This is your Sync Key. Now is a good time to save or print a copy of your key and store it somewhere safe. When you are done with this step, click Next.

  • The Sync Key is used to encrypt your data before it's sent to the Mozilla servers. Think of it as a key that locks your information in a vault that only you can open. This means that neither Mozilla nor anyone else can read your information without having your Sync Key to unlock it.
  • Confirm that you are not a robot by entering the text from the image. Then click Next.
  • You will see a Setup Complete! message. Click Finish to close the setup window and take you back to the Sync panel.

How to stop websites from tracking the location

Most major websites track their visitors' behavior and then sell or provide that information to other companies (like advertisers). Firefox has a Do-not-track feature that lets you tell websites you don't want your browsing behavior tracked. This article explains what tracking is, how the Do-not-track feature works and how to turn it on.Tracking is a term that includes many different methods that websites, advertisers and others use to learn about your web browsing behavior. This includes information about what sites you visit, things you like, dislike and purchase. They often use this information to show ads, products or services specifically targeted to you.
When you turn on the Do-not-track feature, Firefox tells every website you visit  that you don't want your browsing behavior tracked. Honoring this setting is voluntary — individual websites are not required to respect it. Websites that do honor this setting should automatically stop tracking your behavior without any further action from you.
