Sync and Mobile

Sorry; I may not have thought to mention that since I probably subconsciously regard it as a given (as you would with read/unread email). I believe MicroRSS was the only extension I tried that did not track read/unread behavior, though I've uninstalled it since.

As to how much of that gets preserved across Firefox Sync, I'd worry about the extensions that don't store content locally, but to be honest in recent months I've been having a lot of trouble with Sync losing other things that it's allegedly tracking -- like History -- so I may not be able to speak to that before I figure out what the Sync problem is.... My guess is profile corruption, but it's just a guess.
