If I remember correctly, the first time it happened was after a Firefox update on the first computer. It's a Windows 7. All my sync data was gone and using the sync feature never repopulated it. Now, about a month later, right after today's update, the second computer (Windows 10) did the same thing, All the sync data is gone and using the sync button doesn't recover anything. I'm thinking about uninstalling and re-installing Firefox.

Help. I am a writer so my whole world is in these computers.

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.

You can open about:sync-log via the location bar to see if there is a recent log available. You can upload a recent log if the log is too big to put in a reply.
