You can't sync TB settings, accounts etc., but you can manually copy the Thunderbird folder from one computer to another to replicate the entire setup. It even works between different operating systems.

Hi, The problem with the given solution is that it is fine for initial syncing during installation. I want to sync the settings every time I make a change in say, e-mail signatures, when I add a new account, e-mail composition settings, add a new plug-in/add-on, etc.

This will not be possible even if I sync the profiles on cloud based storage services because the profile files are huge to sync every time I make a small change which is of some KBs. The whole file will be syncing when I make small changes. That's because the profile has e-mails also in that file. If e-mails can be removed, I think the file will become smaller but, still large enough to be synced for every change.

Also, if its a burden on mozilla servers to keep/sync this data, we can use our own cloud storage service but mozilla could give a syncing program with in thunderbird for proper syncing over those cloud storage services.

I know this topic has been discussed a lot of times and the only solution on internet is syncing profile only. Please make it like we sync accounts on firefox where bookmarks, passwords, history, etc., is synced.

Please let me know if there is a new solution to this or if this can be added as a feature request.

It would be great if you could solve this! Thanks.
