Yes i tapped sync and on my mac's firefox, the android device is not even shown .. i can see my windows firefox there and see open tabs from there but not from android

why doens't android firefox sync ?

使用系统：win11。我在之前的Firefox上已经登录了账号并开启了自动同步，前天我重新安装了系统并下载登录了账号。登录了账号之后并没有重新同步我的书签，我手动同步多次没有结果，并等待了一段时间自动同步，以及观察是否会同步书签到本地，结果仍没有。于是我尝试用我手机的Firefox登录电脑的Firefox，结果才同步了我手机的书签信息，但我手机的书签信息已经过时。而且电脑的Firefox显示可以和手机的Firefox互相同步信息及标签页等，但我观察后发现并没有完全同步，我电脑/手机的信息及标签页都是一天两天之前的，手动同步后仍然没有看到有更新。我希望同步回服务器的书签信息！

I am unable to send tabs from my desktop devices to Firefox on my Android device.

- All devices are logged into Firefox Sync. - Sending tabs from Android to desktop works fine. - Attempting to send a tab from desktop to Android, nothing happens. Have tried with multiple different tabs from multiple desktop devices, it never makes it to my Android device. - Synced tabs works fine. I can see the open tabs on all my devices from all my other devices, and it stays up to date. - Have tried logging out of sync and logging back in. Didn't fix the issue.

Desktop devices are running Firefox v146.0.1 on Windows Android device is running v146.0.1 on Android 16 (Pixel 8 Pro)

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

I signed into my firefox account on my wife's computer and now ALL of her bookmarks, passwords are mixed in with my data. I've signed out of both accounts on that computer. I've signed out and relogged in on my computer. This is not a temporary issue. All of her data is somehow in my account. This seems like a MAJOR security flaw of the software. Were both using Windows 11 computers.

I have linked, synced, authenticated, the whole nine, all my logins are gone, what’s wrong? I’m logged in on my phone, tablet and laptop, still nothing. What am I doing wrong?

syncing bookmarks between Android Mobile and desktop through shared Mozilla account, but the bookmarks from mobile aren't appearing on the desktop. I can see that both devices are logged in, but cannot see bookmarks being shared.

Hi,

I accidentally deleted my Firefox account on my Windows laptop and lost all my data. However, my Samsung S24 still shows my data, although it indicates that the last sync was on March 6. How can I sync my laptop with my mobile phone to recover the data from my phone? When I click "Sync Now" on my phone, nothing happens. Thank you.

Hello Mozilla Support Team,

I hope you can assist me with an urgent issue. After reinstalling Windows on my PC, I lost access to my Firefox Sync data, which includes years of bookmarks, saved passwords, and browsing history.

Before formatting, I had been using Firefox Sync with my Firefox Account (sometimes signed in via Google). However, after reinstalling Windows and logging back into Firefox Sync, my data no longer appears. At one point, I saw my account showing activity from just before formatting, but now that is gone as well.

I am worried that my synced data might have been overwritten or lost during this process. Unfortunately, I do not have a local backup of my Firefox profile.

Could you please help me: - Verify if my Firefox Sync data is still stored on your servers. - Assist with recovering my synced data or advise on next steps I can take. - Provide any guidance on preventing data loss in the future.

Thank you very much for your help. I look forward to your response.

Best regards.

When attempting to sync my data on my android device it doesn't do anything. I'm currently in the account settings on my phone and when I hit "sync now" it just does nothing.

Hello everyone, my name is Francesco and I have a big problem that I can't solve in any way! I just can’t seem to solve a synchronization issue between two Firefox 135.0.1 (64-bit) installations on a Laptop and a PC (both running Linux Mint 22) and a Firefox 135.0.1 (Build #2016074239) on Android. Can someone please help me? I'm desperate!

Let’s start from the beginning: For a very long time, every time I connected to the internet with Firefox on my Laptop or mobile, my bookmarks would get completely messed up: folders duplicated endlessly, some empty, others identical to the original ones. The same happened with the bookmarks themselves: separators almost all moved to the bottom and multiple duplicates of my countless bookmarks.

After several failed attempts following posts from other users who had the same or a similar problem, as well as some Firefox support how-tos, I decided to try a different approach, which was also described in a post.

First, after logging out of my account on all three devices, I backed up my bookmarks from my PC in different formats (.html, .json), and after closing Firefox, I also backed up the cookies.sqlite, favicons.sqlite, and places.sqlite files—just in case! Then, I deleted all folders and bookmarks from the other two devices.

I then spent the whole afternoon cleaning up my bookmarks on the PC: removing duplicates and redundant folders, organizing separators and bookmarks the way I wanted, and making new backups as mentioned above. After that, I logged into my account from my mobile, triggered a sync from there, then logged into the other devices and started the synchronization on them as well.

But it didn’t work. 😞

PC and Laptop synced beautifully, everything was perfect, but the mobile, despite showing that it was syncing, remained empty—and still is.

I tried several forced sync methods as suggested in some Firefox how-tos (https://support.mozilla.org/en-US/questions/1482205 and https://support.mozilla.org/en-US/kb/how-set-firefox-sync-firefox-android), and I also followed procedures from other posts where users had similar issues, but nothing worked.

I even tried different approaches: logging out and back in first with my PC, then with my mobile; replacing all bookmarks with the ones I had exported in good condition; checking if there was a new update on Google Play. But my mobile remains completely empty—no bookmarks at all.

So, after more than four hours of trial and error, I'm losing my mind 🤯, and I’m also getting seriously exhausted (it’s now 2 AM, and I’ve been up since 5 AM!).

Does anyone have an idea on how to fix this? A plugin? A folder on the mobile where I can manually place the saved files? Maybe a well-aimed hammer strike in a specific spot on the phone? Anything? At this point, even just a good joke might help me get through the frustration. 😜

Now, I just hope I can get some sleep—I’m so stressed that… 😭

Best regards to all, see you next time, and... good night!

P.S.: Sorry for the long post. 😳

I have multiple devices all using Firefox with the same account. On one of the devices I swapped the motherboard and since all payment methods in firefox disappeared. Syncing is active across all devices. On all other devices the payment methods are still available.

On the device with the new motherboard, I tried to disable payment methods sync and re-enable it but the payment methods list is still empty. How can I restore all the payment methods on this device? Why they are not syncing?

Thanks

Firefox on iOS states "No saved passwords" despite my desktop having all passwords and sync turned on. Turning off sync, signing out and back in, deleting the app and reinstall, all did not resolve the issue.

Any help appreciated

1.syncronising in firefox mobile app is awful if you delete some tab witg your linux firefox it wont syncronise with your phone anymore and wont let you to sync manualy(the sync button will freeze) and even do if you dont do anything sync button will freeze and wont sync with linux firefox. when this happen i have to uninstall my firefox and reinstalled it.

I got my mother a new PC. I'm trying to sync Firefox data from the old PC to the new PC. My mother does not have a smart phone.

This isn't syncing PC to smart phone. It's syncing PC to PC. I thought just entering the username/email address and password on the new PC would do it, but it isn't.

[There are still a lot of people who don't have a smart phone and will never understand one.] [If I use my smart phone, it will sync from my data, not my mother's]

Hello,

How can I remove all my saved passwords from Firefox Sync? On my desktop, I went to Menu > Passwords > Three Dots > Remove all passwords, and they're gone. However, on my mobile phone, they're still there. So the sync functionality is borked. The question is, are the passwords still on Mozilla servers, or is just the sync to my mobile buggy?

Even if I were to delete my FF Sync account, for good measure I'd like to manually delete all passwords from it first though.

Any help welcome.

Desktop browser: no Bookmarks Phone browser: Bookmarks Goal: Sync phone browser Bookmarks to desktop browser Bookmarks. Danger: backup Bookmarks before Sync syncs wrong way and no data wipes data device.

Desktop browser sync prompt is wrong: Menu -> tap Sync and save data -> tap Ready to Scan -> scan desktop Firefox QR code -> Pairing unsuccessful. Try again. OK

Here's the correct steps: Sync your Firefox experience -> tap I already have Firefox for mobile -> tap Continue -> Sync Firefox on your phone or tablet -> open Firefox 144.1 (62735) on phone -> tap Menu (3 dots at bottom) -> tap Settings -> tap Sync Now -> desktop Firefox -> open new Tab -> Bookmarks appear -> right click Import bookmarks from another browser to Firefox -> tap Remove from Toolbar.

I installed firefox on other PC and I logged in with my account. Despite having synchronization for passwords, bookmarks, etc., I can't sync my data on my new PC. Why is that?

We just got a mew desktop and I want to sync by android phone Firefox to the desktop so I can retain my bookmarks, passwords, and tabs. I have synced between my phone and my old desktop with no problem. But now when I try to sync my phone to the desktop, all my sync options are greyed out and it won't let me select anything?
