Why am I getting duplicates of my bookmarks in Google Chrome and Mozilla Firefox?
Chrome and Firefox have built-in tools for syncing bookmarks and other data. These tools sometimes duplicate the work that EverSync does. If you are seeing duplicates, try disabling your browser’s built-in synchronization for bookmarks.
For Google Chrome
Open url chrome://settings/syncSetup
Disable Bookmarks sync.
For Mozilla Firefox
Open url about:preferences#sync
Disable Bookmarks sync.
