Why doesn´t the new checklist widget sync between my different computers??

Why doesn´t the new checklist widget (that apperas on a new tab) sync between my different computers?? As it is now, it is totaly useless. If i create a checklist on my homecomputer (logged in with my firefox account) it does not show up on my work computer (also logged in with my firefix account). Eveveything else is syncing fine, but not the widgets...
