Why can't I sync computer bookmarks to iPhone? I can't get my iPhone to show up on list of connected devices. I've tried everything in Help. I have a Mozilla Account. Running 135.0.1

From the Firefox Start Page on my iPhone (running 18.3.1) . . . the menu in the bottom right hand corner does not give me the option to "Sync and Save Data". This is a roadblock for me! I'm not a computer genius but I'm not completely ignorant. I should be able to do this! https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-02-28-15-53-59-c3d764.png Help please!

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.

The title pretty much says it - I have Chrome and Firefox on both my iPhone and my windows PC. I want Chrome to sync with itself on both devices (it does this just fine) and Firefox to sync on both (does this fine too). What I don't want is my history, bookmarks, etc. syncing between Chrome and Firefox. I didn't set this up intentionally but that's what they're doing now - my Google search history from Firefox is showing up when I open the main Google page in Chrome (on both devices). I'm not signed into my Google account in Firefox so I'm a little baffled by how this is happening. I have two completely different use cases for these two browsers and don't want them swimming in the same pool, as it were. Anyone know how to fix this?

You used to be able to right-click a device in the sync tabs sidebar, and choose 'open all in tabs', but since the last update this has gone. So where's that option now? Thanks

Hello,

I was at a friend last night and logged into my monzilla account on his firefox browser. To my shock all his passwords, over 300 of them, got added to my password. I just want to point out here that his passwords were stored locally without an account. As soon as I logged in it started syncing on my account. This is a HUGE SECURITY BREACH and should be addressed immediately. there should at least be a prompt or 2 making sure that I want to add locally stored password to my account or not.

If I had not noticed it at that time I would probably have gotten away with all of his passwords without me or him knowing. I had to manually delete the ~300 entries. makes you think how many times this already happened in the past for others.

Best regards, Remco

I have Firefox on two Windows computers and was wondering what is the proper way to sync them.

One computer is not used often and I want to sync Firefox on it it with the Firefox on the computer I use daily so I want the Firefox that does not have the updated files updated using the Firefox data files on the computer I use daily and not the other way around. So what is the correct procedure to do this other than to make sure the Firefox program version is updated on the computer that is not used often?

Thanks

My password is accepted to get into Firefox but not accepted to sync, I guess it is. It used to do so for years but now will not after the last update. Doing what the threads already suggested does not work in part because my Firefox does not even have the same places to activate what the suggestions offer.

Historically, I remember when you open the `sync` sidebar and right click on the tab grouping (i.e. Firefox on iPad), it opened a context menu where you had the option to `open all synced tabs`. This seems to be missing from the latest version of Firefox (138), but wanted to check in to see if I'm missing something or if I should downgrade my version of Firefox to get that functionality again.

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 would like to know how to get an "app password" for Firefox so that I can sync Outlook with Firefox. I received an error msg that said I needed to get an app password from Firefox in order to sign in to Outlook to complete the sync process. Any help would be greatly appreciated.

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!

(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.)

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...

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.
