How To Turn Off Firefox Sync For Specific Devices

When Firefox syncing is enabled, bookmarks, open tabs, logins, history and add-ons will be available on various other devices which are added to the sync list.

This is handy for ensuring a consistent cross-platform browsing experience. As long as Firefox is installed on different devices with the same account login, this data can be synced.

However, it may happen that a device is now no longer used or doesn’t require this anymore. It can hence be removed from syncing.

To do this :

First, access Firefox preferences by typing in address bar :


Next, go to Firefox Account and click on Manage account.
