السلام عليكم فريق دعم موزيلا،

واجهت مشكلة في ميزة المزامنة على Firefox؛ قمت بتسجيل الدخول لكن لم أستطع استرجاع بياناتي (مثل العلامات المرجعية وكلمات السر).

أظن أن هذه البيانات قد حُذفت من خوادمكم أو لم تُزامن بشكل صحيح.

Emergency!!! I just arrived home from a trip, and on my primary pc, I had saved say 50 tabs over a number of years. I was/am interested in syncing, but I had taken no known actionable steps to do so - but when I arrived home, my primary pc did not open the previous session. I lost everything. Spent hours trying to recover the previous session. Then, I simply decided to go back seven days and restore those tabs. Eight Hundred(!!!!!) tabs were restored, from what appears to be from each of my computers. I am now deleting the 750 unnecessary & repetitive tabs (again, on my primary computer), I am now *scared to death* to boot any of my other computers and have all of my history wiped again. WTF!!!??? Thank you very much!!!

I can see all my bookmarks, passwords, history etc. on mobile but this Sync feature refuses to import the bookmarks to my desktop browser. What is causing this? I have Synced then Unsynced dozens of times with the bookmark option on and off, signed in and out several times, reinstalled Firefox several times. There has to be a way that I can just get my bookmarks onto my desktop. It cannot be this complicated.

Until few days ago i could see all the opened tabs of my first phone on pc using "Tabs from other devices" option. Today i connected another phone and now i canno't see anymore tabs from my first phone. At the moment i don't have access to the first phone as i had to rapair it. Under my mozilla account i can still see my first phone connected.

I have a desktop and a laptop on firefox. I am selling my laptop so i cleared history and deleted all bookmark history.

To my horror, even though i remember i have signed out of mozilla account on the laptop firefox, on my desktop firefox all the bookmarks including bookmark folders are gone. Thankfully, i have a fairly recent backup of firefox userprofile file so i restored them.

However, to my horror once more time, I realize now firefox sync automatically deletes my bookmarks everytime it syncs so i have to turn it off.

How can i make firefox sync to treat my current bookmarks as the latest and stop deleting them?

I am positive that I've been signed into a Firefox browser account for the past several years (to Sync my favorites, etc.) However, my laptop recently crashed and, when I signed into my Firefox account on my new computer, the bookmarks that populated are YEARS old. I'm not sure how this happened. Can anyone help?

My passwords are not showing up on my new computer even though I am signed in to Mozilla on both my old and new computers and have selected for passwords to be synced. Any help you can provide would be appreciated.

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?

Dear Firefox China Team, After reinstalling Windows on 2025-07-22 and installing I signed in with the same Firefox Account (this one). Unfortunately: • No bookmarks, passwords, history or extensions were restored. • I believe “Sync” was enabled before the reinstall with all data types selected. • The UI only shows “Syncing…” but no data appears. Please help:

   Check whether any sync data exists for this UID.
   • If yes, explain why it is not downloading and provide recovery steps.
   • If no, supply official evidence (e.g., server-side log) showing zero data.
   If my data (bookmarks, logins.json/key4.db, form history, add-ons) is on your servers, kindly export it to me in an encrypted archive or provide a temporary secure download link.
   Advise how to prevent this “appears-to-be-synced but actually not” scenario in the future (mandatory manual backup, verification methods, etc.).

Troubleshooting already done: – Confirmed same account, same email. – Reset services.sync.* prefs to default. – Manually triggered sync; about:sync-log shows no error codes. – Created a fresh profile; still empty. Please reply at your earliest convenience so I can continue using Firefox with confidence. I am ready to provide Sync ID or any logs you need. Best regards,

I have a new computer. Firefox looks different. No trouble syncing bookmarks in the past now it wont do it. Cannot figure it out. The icon that aways showed/hid the toolbar in there but doesnt see the bookmarks ,but I can get the book marks up in some strange place I cant even browse to. Just want synced left handed bookmark sidebar PLEASE

Hello, I have added quite a number of bookmarks to my Firefox app on my iPad. I’m set up for syncing to my iPhone. I’ve tapped sync now on my iPhone and on the iPad, but only a few of the bookmarks have synced to the iPhone. I’ve also shut down and rebooted both devices. Both are signed in via email and set up for syncing, so I’m at a loss as to what to do next. Does it just take time? Any advice? Thank you.

My FF sync keeps disconnecting. Recently, I began using Ubuntu from time to time. I use FF on Windows, on Android, and on Ubuntu. The sync used to work fine. But after I started using Ubuntu, I began having problems with sync. Is this a security thing - does FF disconnect itself if it is used on a Linux platforms, or on several platforms? Thanks.

I cleaned the AppData folder to speed up the computer, then it turned out that there were Mozilla files, which threw away all my data form browser. I synced the browser data on the phone, but it didn't transfer everything (history and login data missing). What to do to have my passwords again on the computer?

Choosing, "Sync now" as usual on both Android and iMac does nothing. in Firefox, putting the phone up to the bar code does nothing, except it now tells me I can't use my camera (my camera works).

I know every company feels the need to change settings for no reason, and make things confusing in each update, but this is extreme and has never been a problem before between these two devices.

I have no viruses as I regularly run scans.

Does anyone have updated directions on how to keep the same bookmarks, which is on the only Mozilla account I have, on these two devices?

Why why why does your browser constantly drop sync between my iphone and macbook? It's extremely frustrating to have to constantly sign in - a process that can often take repeated attempts, because reasons. Really poor and a big reason why I'm considering going back to chrome if it's not sorted. Was never once an issue with chrome in over 5 years of use. Happens weekly with firefox

Firefox 140 has lost all my bookmarks and passwords. I have these in Firefox 115 on another mnac but it won't transfer any files when I sync the two laptops and I can't get the new Firefox to import anything from an HTML

What should I do?
