Alright, this is quite frustrating to say the least, and hopefully will not lead me to abandon Firefox once and for all -- third strike, you're out kind of thing. So, since yesterday, my Firefox account will not sync properly. I've lost all my tabs, and none of my extensions are syncing and loading. History is lost too. What gives? Here is the most recent error log: 1646751903906 Sync.SyncScheduler DEBUG Next sync in 3600000 ms.
