HI All Recently purchased a laptop and want to have FF sync with my desk top. I am signed in to both devices with the same account and have checked all settings on both and they are identical. Why are they not syncing?

Recently I had to install a new windows, and I signed in to my Firefox account and found all the data from the previous windows including the open tabs, I could find them from "Tabs from other devices".

But now can't find them any more, although that device name is still there in my account page, under " connected services", please advise.

My tabs from a Windows 10 PC were imported to Firefox running on my Mac Studio ( OS is Tahoe ver 26.2). How do I easily recover these tabs and prevent this behavior in the future? Note: I have copied previous versions of the Firefox profiles files to my active profiles folder, but this does not bring back the lost tabs.

Hello, I’d recently bought 2 new Macs, (for different purposes), as well as preserving my account in my iOS Devices, Since i couldn’t remember my password, (and I’m no longer making music), I’ve changed several settings in my account (but JUST on one of the 2 Macs, and not on the iPhone, either), I was successful in making those changes (for that one Mac), now I must do the same with my other Devicesm they’re both MacOS (Tahoe), and iOS 26, iPad (there are 2 iPads). I’m not a Business, I’ve simply been trying to separate my Studying of a Language, and Classical Indian Literature, i.e.: Vedanta; from my other Mac, on what I’m calling “Secular”, I try not to mix both devices… Do I make sense to you? Essentially, my Firefox/Mozilla account is totally messed up, and not synching.

I have both my PC and my phone signed into the same account and they are both synced. When using the option to send tab to my phone from my PC nothing appears on my phone but there's a pop-up on my PC saying it sent the tab or it was it's a check mark or something that suggests that it knows I wanted to send a tab. And then usually when I am trying to go to bed there is a tab that was playing on my PC so I go to bed and I open up my phone, I select the tab in the sync section and I sync the devices and then I attempt to close the tab. About half the time, honestly probably more the tab will not close and stays active on my PC and it is usually a twitch tab so then when I'm trying to sleep I just hear sound coming from my PC, the tab is gone from my phone so I can't even attempt to hit the x on it again so I end up having to get up and exit on my computer. I think also I've tried to send a tab from my phone to my PC, I could have sworn that was a thing and I don't remember that working either.
