Some years ago I had to replace my PC and thought - Wonderful - just use sync to bring back all my tabs etc into the new PC...

The long and the short of it (in the past), was that Firefox decided that the new PC was the one to be synchronising source, and promptly removed all the apps/tabs etc. so sync was in line with the new PC - erasing all the app data. I understand there is no 'Master' sync account.

The question is, how can I stop Firefox initially migrating the Firefox app data in the wrong direction? I know that the app/tab data is currently still correct as my laptop still has all my apps etc. Is there some way to stop Firefox thinking the latest clean browser on the new PC has the correct (None) apps etc? Has the laptop to be logged-in and currently on-line before starting the new PC with Firefox? Is there a process to follow with a new 'un-synced' PC?

Sorry if I'm making things sound difficult, but don't want to loose everything which is currently correct and still these within sync data. It's maybe something that can't happen in these later versions of Firefox, but I want to be sure before logging in my new 'Blank' PC.

I’ve used Firefox for many years on both my pc and mobile and keep them both up to date and use sync. However recently when using the app and wish to enter my username and password with autofill, after using my phones passkey, I can find the website on my password list but the username and password are not being displayed and will not autofill to the website I am attempting to use. However, when I am using the website on my pc I have no issues at all. Even after manually entering the username on the app password list and attempt to access it again at a later time, the username and password are not being displayed or deleted. Please see attached photo as an example.

I have Mac, Windows, and Linux boxes. All show connected to Firefox Sync, however, bookmarks etc are only actually in sync between Windows and Linux. I've tried logging out on all devices, resetting passwords, reinstalling FF on the Mac. Can't seem to get it to work.

I am using a Android device, I am finding sync issues in login to my browser, a computer screen is active on my device may be through wch a shared browser is connected. I am not sharing my connection with any one nor I have a computer system for my internet access. While signing in its showing a authorisation error. My internet connection is totally private and confidential & personal wch I am the only user. Why is that I am finding authorisation error and who is the one who authorises me...?? I don't have any authoriser for my acount or browser
