[Tip] Disable or Remove Firefox Account Sync Feature in Mozilla Firefox

Firefox Account previously known as Firefox Sync is a built-in feature of Mozilla Firefox web browser which allows users to automatically sync various items such as bookmarks, login passwords, options, etc among different computers and devices.

You just need to create a new Firefox account to use the sync feature and then you can select which items should be synced on the cloud. You can sync following items using this feature:

• Bookmarks
• Open tabs
• Logins
• History
• Add-ons
• Options

Once you start using this feature on a device, you can use the same Firefox account on a different machine to restore all the synced items. So its a handy feature of Firefox to use same bookmarks, add-ons, preferences, etc on your multiple devices.

You can access Firefox Account Sync feature using the main Firefox menu (hamburger menu) or using “Firefox Account” tab present on Options/Preferences page.

But if you don’t want to use this feature due to privacy issues or safety concerns, you may want to disable or remove this feature from the browser.

Older versions of Firefox browser didn’t provide any option to disable or remove the sync feature but the new Firefox 60.0 and later versions come with a built-in option to completely disable or remove Firefox Account and sync feature as shown in following images:
