After reinstalling the system there are no bookmarks in the FireFox browser Good day. After reinstalling Windows, re-installed the FireFox browser. I went under my account, but the saved bookmarks are not synchronized. Bookmarks are all gone. If any bookmark saving history. thank

Unfortunately if you didn't do any backup of the bookmark or not syncing prior system reinstalling recovery can't won't happen.

You can look for a "C:\Windows.old" folder to see if it has your old data.

• C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

"AppData" (XP: Application Data; Mac: ~/Library; Linux: ~/.mozilla) is a hidden folder.
