Hi there, thanks for the report! You're right, it looks like we don't sync any of the network.proxy.* prefs that dialog sets.

In the past, we haven't been sure about the right way to support settings like this, because synced preferences are global. So (for example) if you're signed in to Sync on your home and work computers, and you set up a proxy on your work computer...oops, now your home computer will use the same proxy settings! In some cases, that might be what you want; in other cases—if you're only using a proxy at work, for example, and it's behind a VPN or requires you to be connected to the work network—it'll break your internet, with no easy way to figure out why.

If you'd like to sync these settings yourself, please follow these instructions to sync custom preferences. You'll need to add the following prefs to about:config, all of them set to true (sorry it's a hassle to do for this many prefs):
