Well, I've been doing Firefox sync for a long time, and it seems to work pretty well. But I'm a little confused. What EXACTLY is going on? Note: I do NOT want to know how to set up sync. I know that.
First question. When sync is automatic, when exactly does it do it? I pull down and do "Open menu" with the three bars, and then hover over the sync arrows-in-the round. It might say "Last sync: 5 minutes ago", and it might say "Last sync: 5 seconds ago". Nothing happened on my Firefox five seconds ago or five minutes ago. So who told it to sync? What determines when it is supposed to sync? I presume Firefox automatically does a sync if you change a bookmark or password.
Second question. What exactly is a sync? I gather that if the sync file (containing bookmarks and everything) in the cloud is younger than the local sync file, the local sync file will be replaced by the one in the cloud. If the sync file in the cloud is older than the local sync file, that sync file in the cloud is replaced by the local one. Is that what's going on? That is, it's all about the time stamp? Do not tell me "Sync lets you share all of your data and preferences (such as your bookmarks, history, passwords, open tabs and installed add-ons) across all your devices." I know that.
Third question. Let's suppose I want sync to ONLY be manual. As in, it will ONLY sync when I do Tools>Sync Now. How do I set it up for that?
