Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

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,

When following the instruction to sync bookmarks on Android phone it leads me to items that are not there. Open Firefox mobile on phone. Ok. Hit the 3 dots drop down. Ok. Choose sync and save. Not there? I click my email and it shows sync. I click that and it shows the last time I sync my phone. 0 minutes. Ok. It shows a QR code to scan from the Firefox app. It instructs to click ready to scan. That's not there either. If instructions lead you down paths that are not present, the instructions are useless. Anyone else having this experience? Thanks..........

Hi I have a firefox account which I use on 2 macs and a PC as well as an android phone. For the past few months non of my book marks, passwords etc are being synced across the system and I have now completely different book marks on different devises. I have synced each computer multiple times without effect. This used to work perfectly before I changed my password a few months back. It is now reaching a point that firefox is no longer usable for me?? Thanks for your help

I moved to the Firefox flatpack after the Debian version couldn't display the code inspector/ web developer tools anymore (it was blank amid other likely javascript-based rendering errors). I only include this context in case some one else has the issue and searches for it.

I want to sync all my tabs from the Debian version to the flatpack version and similar to this solved issue I cannot access those tabs from the firefox view. However I am also unable to access these tabs from the sidebar. I am only able to access these tabs from the account menu but this would have me open each tab individually which is not feasible for me.

Is there a way to fix the "Check your internet connection If you’re using a firewall or proxy, check that Firefox has permission to access the web." error that comes up in both the Tabs from other devices sidebar and Firefox View menu?

All my saved passwords are missing. I am synced and logged into an Android phone. I usually use an iphone but have not checked syncing there yet, or on a computer/laptop.

My account won't sync my old passwords and browser history. I recently reinstalled windows and when I tried to sign in to my mozilla account my data wasn't there.

I recently upgraded from Windows 10 to Windows 11. I was under the impression that my bookmarks would be saved to my Mozilla account and I could then log in on the new computer and the bookmarks would come over also. Is this accurate or will I have to go about recovering my bookmarks a different way?

As of now when I log into Mozilla I get a message at the top saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. I clicked Learn more and tried the troubleshooting options, but no luck in fixing the message or issue. Thanks for your help.

I wanted to synch my current settings in my browser to import them on my new laptop. When I tried to login to my account, I the message from the attached screenshot appeared. So I created a new profile, got my stuff back to what it should be and then deleted the "new" profile. But now every time I try to get into the correct profile and login into my account, I still get the message from the screenshot. I never ever synched with another profile before and never had an issue in the past. Right now I am rather pissed off, because I lost atleast some of my bookmarks during this whole ordeal.

Hi there,

I just got a new laptop a few days ago and I signed into my Mozilla account but none of my bookmarks or history is pulling up. Does it take a while?

因工作需求，分别在五台电脑登录我的火狐账号（国内版账号），进行书签操作共享。 现在不知道因为什么问题导致，是火狐的历史书签没法多端同步（自动/手动均无效）， 其中尝试设置了 排障模式/about：config部分参数： ①contextParam--fx_desktop_v3； ②identity.fxaccounts.oauth.enabled设置为false，仍然未解决问题。 有解决方法方便直接联系3003378498@qq.com，求求大神帮帮忙，谢谢

Hello,

I recently reinstalled Windows on my computer and expected Firefox to sync and restore my saved passwords, as I had enabled Firefox Sync before reinstalling. However, after syncing my account, my passwords did not appear, and I am unable to access them.

I have already tried the following steps:

   Checked the sync status of my Firefox account.
   Ensured that I am signed into the correct Firefox account on my browser.
   Searched for any relevant troubleshooting steps but haven't been able to resolve the issue.

Could you please assist me in restoring my saved passwords or provide any guidance on how I can retrieve them?

Thank you for your help.

Best regards, Tameem

I'm attempting to set up Firefox in a newly installed OS and have logged into my Sync account. Many aspects seem to be loaded in, but the status via the Settings is stuck at "Syncing..." despite waiting several hours. Quitting Firefox results in a crash window popping up.

There are no files in the weave/logs directory. The weave/failed directory has multiple json files; most almost completely empty. addons.json has an ID, but that's pretty much it.

Deleting the .mozilla directory and starting over yielded no change in behavior.

Any help would be appreciated. Thank you.

I have been trying to enable Firefox Sync on my Windows 11 PC (Firefox 145.02). I open the Firefox Sync window, I click on Log In, I enter my e-mail and click on "Sign up or Sign In" and then the view freezes and I never get any further. The attached screen capture never changes, no matter how long I wait.

Hello,

Earlier today I reformatted my device but when I logged in to firefox I can only see my history is getting synced my bookmarks are empty, I've checked and bookmarks are check off and they should be synced. How do I get them to sync? It has worked fine in the past. Thanks.

Sync works fine between my Android phone and my devices, in that I can see open tabs on the phone from both devices. But what does not work is sync between the laptop and desktop. They are both listed as connected devices along with the phone, both are signed in, both synch with the phone but neither will sync with the other, so I can't see the open tabs on either device. Is this an issue or is it by design? Thank you.

I recently got a new PC, and all my information was erased from it. I thought it wouldn't be a problem, as I expected to get everything back by logging into my account. However, after trying to sync my account for hours and searching on Google and YouTube for solutions, none of my information has returned.

When I contacted the person I bought the PC from, he said he couldn't help because I had forgotten to do something, possibly related to a Firefox update. I'm devastated and was hoping someone here could help. Is there a moderator or administrator who could assist with account recovery?
