Now all my bookmarks, history, passwords and the like will be stored on a centralized server?

The decentralization, especially in the wake of the NSA/GCHQ revelations, was one of its main advantages.

Sigh. I may well have to turn Firefox sync off then.

They were already stored in a centralized server. They were just encrypted, and they'll continue to be.

Ah, looks like you're correct. https://wiki.mozilla.org/Labs/Weave/Developer/FAQ#How_do_use...

I'm still a little unsure if this new system is less secure, however.

With a password, of course it is.

a) You can run your own server.

b) It's encrypted on the client - that's what the password is used for.
