"Most of this can be done with Dropbox, I believe. Here's an example of how to symlink a Firefox user profile for use with Dropbox:

Find the directory containing your Firefox profile. A default installation places this folder in %APPDATA%\Mozilla\Firefox
Copy that Firefox directory into your Dropbox folder.
Delete the original Firefox folder.
Use Mklink to create a hardlink between the new and original Firefox folders.

If your Dropbox folder is in C:/ you can use the following command:

mklink /J %APPDATA%\Mozilla\Firefox C:/dropbox/Firefox

You can also modify where Firefox would save its profile data to be where your dropbox directory is in:

C:/Users/name/AppData/Roaming/Mozilla/Firefox/profiles.ini

**I gave examples for Vista/7, but it'd be just as applicable in any other OS I'd imagine.*"

"You could try using portable FF and Thunderbird from a USB key.
This would store your bookmarks, settings, emails etc in one place.
(this might only help with one type of OS though)

There are several online bookmark managers and you could use web based email."
