How to sync Firefox settings between multiple OS's on one computer or multiple computers

I have three OS's on a single computer (XP SP3, WIN7 & WIN8. Each OS has it's own Firefox install and of course, different settings in each since they are all handled separately, I have no idea how to synch the user-data from all three different Firefox installations. My goal is to be able to boot up in any of the OS's and have the same user settings/details across all three.

Once I get that figured out, then I can try to find a way to synch Thunderbird across all three OS's so that mail collected or sent in one OS is shared or synched with Thunderbird on the other two OS's.

It's probably a tall order and not possible to accomplish, but if I don't ask then I'll never know.

Thanks in advance for taking the time to read this.

hello fastlane, for firefox you can use firefox sync to share bookmarks, passwords & history between your three OSs - How do I set up Sync on my computer?

& for keeping your mails synced it's possibly the easiest way to use a mail-provider that offers IMAP, which keeps the mails on the server so that your mail program on any OS has the same data when it's connecting... (but we're not specialised on thunderbird here, you might head over to for more detailed questions).
