Diễn đàn hỗ trợ Firefox

I've got Firefox on three devices and I'm looking to get a little more fine grained control between the synced data.

Ideally I want to sync passwords between all three but only sync bookmarks between two of them. This doesn't seem to be possible with the current options. Is there an alternative short of manually exporting and importing on the devices I want to keep in step?

I reinstalled Firefox on my laptop after it crashed. I also have Firefox on my iPhone. The profile there is up to date. How do I sync that profile to the laptop installation?
