Firefox went wonky on me, so I needed to refresh it. I didn't want to lose all my data, though, so I logged out of my Firefox sync account and then refreshed. After Firefox was done, I logged back in -- but now everything is gone. How do I get it back? I was trying to AVOID this very scenario but now I'm stuck dealing with it!

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.
