"Google Browser Sync" for Firefox
For my support work, I use several machines with different operating systems:
a desktop with Windows 2000 and a laptop with Windows XP and Red Hat Linux (dual boot).
I use a very useful extension - "Google Browser Sync" - to synchronize my different browser settings.
This extensions synchronizes:
- the bookmarks
- the history
- the persistent cookies
- the saved passwords
- the tabs and windows
You can encrypt the information (cookies and passwords are encrypted by default).
The extension increases the start-up time of Firefox, but it's minor compared to the benefit of using it.
