Recently I had un/reinstalled my firefox via snap and apt from linux. I'm signed into my account yet locally I'm not getting data to sync across devices. Any idea?

I've got Firefox on three devices and I'm looking to get a little more fine grained control between the synced data.

Ideally I want to sync passwords between all three but only sync bookmarks between two of them. This doesn't seem to be possible with the current options. Is there an alternative short of manually exporting and importing on the devices I want to keep in step?

Firefox is installed on my desktop and on my cell. How can I get my cell to show all bookmarks that I have on my desktop? I already synced a few times but no change!

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!

I have been using Google Chrome for years having set it up to open the same 8 Tabs and several bookmarks. What I liked about it was that no matter what PC I went to once I logged into Chrome I was given the same confiuration across several PCs including Linux which I am gradually moving to. However to date I just cannot get my other PC's whether Linux or Windows to do the same. What I want to know is that can I open Firefox on any other PC, login and and get the same configurantion automatically? .

(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.)

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 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...

Fred

I like the idea of Firefox, so I wanted to migrate my passwords to your service

During the migration, I repeatedly ran into the problem that when using "Search Firefox" to log into accounts on other devices, even after a rough synchronization in Firefox itself, the saved passwords that can be viewed in Passwords in PC do not immediately appear in the pop-up window in Android smartphone, which logically should not have such problems

In my opinion, this will discourage almost all users who want to "move out" of Google services

I have bought a new laptop and I want to synchronize data from old one to new one. Unfortunately, the old laptop is off and I cannot use it. Instead, I have also the mobile android chrome which I can use. Please advise.

The welcome addition of Tab Groups I just noticed on updating my Firefox, however looking through help and documentation, it's not clear to me if Tab Groups syncrhonise across devices (or at least desktop devices) as like recently added to Chrome. Wished to check if this is case

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.
