Does Firefox “Mirror” Browsing Activity When Sync

My work is trying to fire me because they say Firefox was mirroring my activity at home and vice versa. I.E If I opened a tab at home it when then open a tab and attempt to connect to same website on my work computer in the office.

I’m fairly certain it doesn’t cause that would be wildly unnecessary for what sync tabs is trying to accomplish but I used wireshark to watch for outgoing connections on my home desktop and opened a tab on my phone and my personal laptop and wireshark never detected outgoing connections to the tabs on other devices

By "outgoing connections to the tabs on other devices" I mean the desktop running wireshark never detected connections being made to the website opened on the other devices

It seems it used to do that, but when I recently tried, only the favorite sites where available

If you use Sync then you can include syncing history and open tabs.

I guess to phrase this another way is anyone aware of Firefox opening connections to websites in the background when syncing or does it simply share data like the URL and Title.

When reading through this I think it doesn't: https://mozilla-services.readthedocs.io/en/latest/sync/lifeofasync.html

You can see synced tabs in the "3-bar" Firefox menu button drop-down panel if you click your account email. This is also available in the sidebar.
