My firefox sync between my desktop and android device was working fine until recently. However, since the latest updates the my android device won't sync at all (no bookmarks, history, tabs or anything really). I have checked my settings to ensure auto sync is on, and have tried uninstalling, and then reinstalling the app. Every time I try to sync, my device appears to have synced fine (giving the time since last sins=0 min notice), but the tabs, history and bookmarks themselves are not updated. Every time I want to sync my device to my desktop, I have to remove my account and then add it again for it sync.
