Hi Y'all,

I have Firefox syncing to about 6 different systems (Windows, Mac, iOS) and have run into a situation where Firefox is wiping years of my synced data when I quit and restart Firefox. I sync all of items that can be synced and this has served me well for many years. What happened:

1. I logged on the admin account of a Mac where I previously logged in before and used Firefox with sync enabled. The machine had the initial Firefox short cuts: AP, Amazon, etc.
2. I enabled sync and did a 2FA but the my normal Firefox home page did not appear. So pressed the Sync now button to no effect.
3. When Firefox started, I did see the usual message that "It looks like you haven't started Firefox in a while. Would you like to refresh Firefox." I think that I closed that message but I could have accidentally refreshed Firefox for that account on that system.
4. I gave up and did what I needed to, closed Firefox, and logged out.
5. That evening when I was using Firefox on a Windows machine I could see that the sync information reduced to almost nothing from before the last day. The day I saw the saw the same and started to worry.
6. However, the Firefox on my main two Macs still had all the data. As a test, I deliberately closed Firefox on one of those two Macs. When I restarted, the synced data was wiped. This leads me to believe that somehow Mozilla's servers are holding the data based for the almost empty content of Firefox that I had on the administrative account that I synced.

So in other words rather than importing my data from Firefox when I connected sync, sync exported the settings of the Firefox account I was using in the admin account. I am writing this from my other main Mac which still has full information and I would like to force the synced information on this Mac to override or at least merge with what is on the Mozilla servers. Can this be done? I am 99% sure that if I close Firefox on this machine all my settings will be wiped. For now a I believe that I still have the correct sync data on at least this Mac, my iPhone, and few other Windows and Linux machines. I am in particular worried about losing the hundreds of passwords that I have saved. I forgot to check if the passwords were overwritten when I restarted the first Mac but I'll bet they were.

Thanks for any help...

Dear Mozilla Firefox Support,

I am seeking clarification and assistance regarding saved login details that appear in my Firefox browser, both on my laptop.

The situation is as follows:

At some point in the past, I mus thave attempted to access the Plenty of Fish (POF) dating site via the app on my iPhone. Alhtough not presently active, my iCloud account shows a history of the app being downloaded, and stored in the cloud.

I do not recall ever completing an account setup or using the service, but when I check Firefox on my laptop, I can see a username and password saved under Privacy & Security settings for POF.

I am trying to understand whether these saved credentials could have been synced between my iPhone and my laptop at the time of the attempted registration, meaning that they were stored automatically even if I did not intentionally log in on my laptop.

My specific questions are:

Do the Firefox saved logins on my laptop and my iPhone interlink automatically if Firefox Sync is enabled? (i.e., would login data entered on my phone app/browser be stored in the Firefox passwords list on my laptop?)

Is it possible to determine whether the saved username/password for POF was stored via the iPhone app/browser rather than being typed directly on the laptop?

I belive that if login attempts fail due to a non-existent or corrupted username/password, Firefox still store the login attempt details (username and password) even if the login itself did not succeed, can you confirm this? Is there a way of telling which it was failed/sucessful

This is a sensitive and personal matter, and I would greatly appreciate your guidance and any clarification on how Firefox may have stored or synced these details.

Thank you for your support.

Kind regards, A

Hi, I've seen others ask this same question in archived posts with no proper answer.

How do I select all tabs to be imported from a synced machine? I have the list on my sidebar, I can import or close one tab at a time, but there is no menu available to select them all (there are many). Right-clicking on the device name etc. does nothing.

Windows 11, Firefox 141.0

Many thanks for any help!

(This is copied nearly directly from a post on r/firefox made a few hours ago—I decided it was best to spread it here for more exposure. The only change was the removal of the add-on names from the title due to character limits; these are Form History Control and Text Area Cache.)

I hope the title explains what I am looking for well. My main computer has had... spooky behavior with its file system recently, and I have been recommended to make a back-up, format my drive, and re-install my operating system (possibly upgrading from Windows 10 to 11 in the process). The biggest hold-up to me doing so is this, as I have no idea how to transfer the extension data between installs, or convert it into a human-readable form. The sheer number of writing drafts in those extensions both make losing them an unacceptable situation and copying the data manually into a document entirely impractical. So, can anyone help me with this? For context, I was on Firefox 138.0 when I stopped using my main computer due to those issues. (Note: It will certainly last long enough to do the Firefox Syncing and other back-up operations, just not for many more weeks or months.)

I have purchased a new computer and do not want to loose the info in my Mozzila account. How do I install the old account to the new computer? Old computer has windows 10 os new computer has windows 11 os.

I've just gone through having to reinstall windows due to 24H2 and I've got Firefox back thankfully.

My problem is that the sync account has created another device name (as I hadn't restarted after renaming the computer).

Can I get my old device profile back and discard the new one?

Can I just uninstall firefox then reinstall now the computer has been renamed after a restart?

With thanks, Dave

Hi I have used two computers for different purposes and places, but have had the same account with passwords synchronized on both machines. I would like to synchronize everything - especially bookmarks and payment methods - on the machines. My question is: what happens if I 'just' set synchronization active in all sections on both machines? Is one of the machines considered the 'master' machine, so its 'content' is synchronized to the other, so that content that was not on the 'master' machine is deleted? Or is everything preserved, so I have all content from both machines on both machines? Where can I possibly find more detailed information about this? Thanks in advance.

What is best way to transfer my Firefox acct from Win 10 computer to Win 11 on new computer? Please give detailed, step-by-step instructions. I am not tech savvy and have no tech help. Thank you. Tasha

I can see no way to download passwords or bookmarks on my android phone, so I can email them to myself, open on my PC and add them to PC Firefox. I have signed in to the same account on both devices, and turned sync on on both devices. I receive no passwords or bookmarks on the PC. I had to re-install Windows 11, and now I cant get my passwords or bookmarks onto my PC.

Cannot take screenshot of passwords on android - screenshot is blank.
