This add-on doesn't synchronize among different windows.
When I read sth in one window, it is still shown as unread in another window (well, I only wait for a minute or so, so I don't know if it is fine after a longer time~~). And the "update when firefox start" setting actually means update when a new window is openned, which I suppose is not that effecient (and not safe probably).

BTW, how can translate it? I can help with Chinese translation (if there haven't already been one)~~
