I had been collecting bookmarks in my Firefox account for at least 5 year. But yesterday after reinstalling Windows, I logged in my Firefox account in Browser, clicked sycning button and got nothing. Maybe it was rewrited by a new data, but all of my old bookmarks are lost now. Is there something I could do to restore my previous history?

Thanks a lot.

Hi

Thank you for your question about the Firefox Sync service.

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. Please have a read of this article.

If you have a copy of your data on a mobile version of Firefox, please follow these instructions to connect it to Firefox Sync to copy your data.
