I use Firefox on two different computers. On one, I'm logged in with bookmarks syncing enabled, and on the other one, no Firefox account is added. I do bookmark and tagging on both. I wonder what will happen with the bookmarks and their tags for the same bookmarked websites after I sign-in on the other computer? For example, on the signed-in computer '''mozilla.org is bookmarked with tags: Firefox, mozzila''' and on the other computer without account '''mozilla.org is bookmarked with tags: browser, application''' After I enable syncing on the second computer, will I get a result of the merged synced bookmark: '''mozilla.org with tags firefox, mozzila, browser, application''' or it will get overwritten?
