TRANSLATION ONLY -------------------------------- account in Firefox and missing bookmarks, passwords, sites! Hello, I created an account in Mozilla Firefox for a very long time. I saved passwords there, sites needed for me to bookmark everything and always worked perfectly, reinstalled Windows, then downloaded Mozilla Firefox logged into my Firefox account and all the bookmarks, passwords, sites were always in place. Today reinstalled Windows installed Mozilla Firefox, went into a Firefox account and found that there are not any bookmarks that I saved for many years. One password or anything that disappeared and it's not clear why, although last night I still used bookmarks and passwords. Synchronization options: Choose what you need sync on your devices using Firefox. 1. Bookmarks, 2.Open tabs, 3.Logins, 4.History, 5.Additions, 6.Settings all these options are included! and again not for the first time I use Mozilla Firefox, how many times already over these years I reinstalled Windows and Mozilla Firefox always worked fine. It was this function that liked Mozilla Firefox that all sites, passwords and bookmarks are saved on the account and do not need to constantly search for them and enter. How to recover all those bookmarks, passwords, etc. what was on the Mozilla Firefox account !? ------------------------------------------------------------------------------------------------- HI, well the reinstall of Windows and uninstall of Firefox took out a token that is used to communicate to Sync. When you reestablished connection the token would not have the same information as would think all was deleted. You do not mention about un-syncing Firefox before you did the above, this may have helped. You do not mention another device that you could recover you info from : So It appears from your question, that you are using Firefox Sync as a back up service. This is not what Sync is designed to do. The Firefox Sync service takes a copy of the data you wish to include and transfers it to a second device (typically a mobile device such as a tablet or a telephone) running a copy of Firefox. The storage in between all attached devices is both temporary and fragile and is not stable enough to be (and is not designed as) a reliable backup service. If you have a copy of your Firefox profile for desktop Firefox, you may be able to recover your bookmarks and other data.
