User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release) Build ID: 20140325030201 Steps to reproduce: Remove old sync account (the cool old working sync). Sign into new sync (newfangled Firefox Account). Enter Sync settings (see screenshot). Actual results: Sync categories are grayed out and force checked, causing distress in user due to desire to never ever persist some categories. After a short rant, reopening the settings has the category sync state synced against account and are interactable. Expected results: If the uninteractable state of the categories is due to syncing them against the account, it'd probably be nice to either have a notice that this is in progress, or let user interact with them anyway with all the fun races that entails.

Hi Lars, thanks for the great bug report! I'm actually working on this code as we speak, and we expect to land by EOW. Duping to that ticket now.
