Thanks to reader Bob from the UK for pointing out the excellent FoxMarks plug-in/service. It just makes sense.
FoxMarks lets you synch your Firefox bookmarks with a central server and keep various machines (office/home, PC/Laptop/Zonbu) in synch. It also means if any one of them goes walkabout on you you don’t loose your bookmarks.
Quite frankly, this is the kind of functionality I would expect for my Zonbu bookmarks already, given the online storage/cachefs approach Zonbu takes. But hey, you can’t have everything.
In the mean time, hot rod your Zonbu with FoxMarks.
