Firefox keeps losing sync settings and asks me to set up sync after every restart

I set up firefox sync and it seems to work for a while. After a time the File menu shows "Set up Sync..." instead of sync now. If I try to set it up it says my email address already in use. In the end I have to delete my sync account and start fresh on all my computers.

Question: Why does firefox keep losing my sync settings and asking me to set up sync all over again?

I think you are not loosing anything. In "Set Up Sync...", go to "I have an account" then give here the code which you get from your previous system.

hi gurumukhi,

Thanks for the reply but I think you misunderstand the problem. I'm not asking how to set sync up again, I'm asking why Firefox keeps losing the sync settings in the first place. It often gets lost on all 3 of my computers so even your suggested solution doesn't always work and the only way out is to delete the account on Mozilla's website and set it up on all the computers from scratch.

I thought about this a bit more and it seems the one constant in causing FF to lose the sync information is that it happens soon after a FF version upgrade. This is recent as of about v22 or so - used to work perfectly before then.

If anyone knows of a solution that would be great.

Thanks
