I've signed in and synced everything from my iphone to my windows computer. When I go to the sync tab view on my computer, it says that my iphone isn't connected. On my iphone I can see the tabs that are from my computer, though. I'm not great with technology so this may just be a simple thing that I'm missing. Would appreciate any help :)

I opened up Firefox for the first time in a while on this newer laptop, and all of my bookmarks are missing. I recently opened Firefox on my work desktop, and they were all there.

Any help would be appreciated!

I'm trying to sync my tab groups across my desktop/laptop. I have sync enabled through the settings and I've checked every box, but I don't seem to see an option for syncing tab groups specifically. It syncs all of my bookmarks and active tabs, but the groups seem to be unique to each device. Is this feature available? I might be looking in the wrong spot so if anyone has any insight that would be great! Cheers

With Firefox Android on my tablet, bookmarks are not syncing that i see when logged into my Firefox account on other devices. I tried logging out and in to my Firefox accont and also unchecking and checking the "sync bookmarks" box. Firefox Android says "bookmarks are now synced". But they aren't!

Lately I installed a new PC, and tried to download FireFox and sync my data. But my data seems like a few years ago, not as new as another PC I have now. I'm sure I have logged in with same account on them, how's this happend?

I have been using a new windows 11 laptop, but which hasn't been able to import my favorites/bookmarks as well as password data from my previous (also running firefox) Windows 10 laptop. I performed syncing, but which didn't seem to help.

I tried to sync my desktop and mobile today. Nothing loaded to my mobile a fact I am now gratefull for because my desktop did sync with the cloud ERASING an entire year of deleating broken bookmarks. What I want to know is how to deleate the cloud so this never happens again!

For years using firefox, I have had all of the bookmarks and login information retained by Firefox on my old HP laptop, but after buying a new Windows 11 Laptop and performing the Firefox syncing, none of the bookmarks/favorites and none of the password (and other items that used to self-populate) are there on my now machine. This has caused an emergency situation since my old laptop is now fatally broken. I'm wondering how to start diagnosing what the problem is, whether the "syncing" actually occurred within my account, while the syncing process indicated no problem. The new machine has it's own Bookmarks toolbar showing, but only contains a few new bookmarks that I have manually added.

Everything is gone, I have had to reinstall windows 4 times in the last week with a new PC and now all my sync data is gone...Chrome remembers everything fine and Mozilla did remember everything until this install and now its not syncing anything.

If this stuff is gone so am I.

Have tried logging in with my google account, tried logging in with Moz account, tried sync button over and over tried restarting, tried uninstalling and reinstalling and manually deleting all the folders STILL NO SYNC DATA AT ALL.......

Hi! I recently lost my old laptop and I'm trying to setup my new laptop without a backup. I was logged into my mozilla account on my old browser before I lost it, but I'm not seeing any of my old tabs, bookmarks, and extensions from my old browser syncing to my new browser. Is there anything I can do to retrieve this data without having access to my old laptop? Thank to anyone who can help!

Hello Firefox Support Team,

I am facing an issue with Firefox Sync. I have logged in using the same Firefox account on my new device (or after reinstalling), but my bookmarks, saved passwords, and other synced data are not appearing.

I have tried signing in again, checked my internet connection, and confirmed that I am using the correct Firefox account. Despite this, nothing is syncing.

Please help me restore my synced data. I would really appreciate your support.

Thank you, Shubham Sen

Firefox desktop saved logins not appearing on android. Sync enabled on both devices yesterday. Previously worked fine, kinda frustrating having to manually re enter everything.

The Firefox browser on my computer suddenly wouldn't open, so I uninstalled and reinstalled it. After logging into my account, my original bookmark list disappeared. I also have Firefox on my phone, but the bookmarks won't sync to my computer. What should I do?

Hi,

I recently noticed an unknown Outlook/Microsoft account (oliveconscious13@outlook.com) saved in my Firefox logins. The email and password appear to be randomly generated, and the account’s preferred language is set to Russian. I have never seen or used this account before.

Here are the key details:

My Firefox account was created on June 8, 2025.

The unknown Microsoft account was created on July 8, 2025.

I only have two devices connected to my Firefox account: my Mac (where the account first appeared) and my Windows PC.

The account is also showing up in Chrome’s saved passwords, which I never intentionally synced with Firefox.

This is a brand-new Mac purchased directly from Apple, so I know it wasn’t a used device.

I’m trying to figure out:

How this account was added to my saved logins.

Whether this was synced from another device.

If there’s any security concern or if my account may be compromised.

Could you check my sync history or logs to see which device added this login, and advise on how to make sure my saved logins are secure?

Dear Firefox Support Team,

After reinstalling Firefox and logging into my account, my saved passwords, bookmarks, and other data have not synced and are missing.

I have confirmed I'm using the correct account and that sync is enabled for all data types.

Please advise on how I can recover my information. Thank you for your assistance.

Sincerely
