Diễn đàn hỗ trợ Firefox

The title pretty much sums it up. I even tried drastic measures such as logging out then completely uninstalling Firefox and removing any leftover data on both platforms. After reinstalling and connecting to the Firefox account they will sync with previous data but any new data I add on Windows won't show up on Android and vice versa. I also obviously tried forcing a sync manually... I really wish I didn't have to switch to another password manager any help would be greatly appreciated! :)

my computer broke about 2 months back and i am wondering if i can access the tabs from that device from another device since the original was synced (or i.e. is the a function in Firefox that lets me see all synced tabs from all connected devices)

going to the regular synced tab area there isn't anything from that computer there,

Firefox v.99.0

I have had several computers and a phone synced with Firefox. Recently, my mac book had to be wiped and OS reinstalled. Since then I have been unable to sync to my Firefox account on that laptop. I enter my standard email and the same password as on my desktop, but get an error stating, "Incorrect Password".

Following suggestion from an older thread with the same problem, I installed a nightly build on my desktop and tried to log in with that, unsuccessfully. Same problem. I used my same email and same password, but the nightly build version of Firefox reported the error, "Incorrect Password".

While thinking about this, I checked my newish phone and found it was not synced either. Using my email and password, I was unable to get it to sync. However, I was able to sync the phone using the QR code. So my phone is now synced to my Firefox account.

I really want to get the laptop to sync to my Firefox account and am mystified as to how to track down what the problem might be.

I know there's [[an article|https://support.mozilla.org/en-US/kb/sync-custom-preferences#w_sync-custom-preferences]] on how to sync custom preferences. I wanted to sync my toolbar customizations and some other preferences like disabling disk caching. And I don't even have other firefox instances, instead I just want to sync only on one device, so that I can continue the same setup when I signin later on the same device.

I've tried to add services.sync.prefs.sync.browser.uiCustomization.state, "services.sync.prefs.sync.browser.cache.disk.enable" and set it to true. But it doesn't work. What am I missing? No one seems to address this. May I am missing something.

This all started when i wanted to use a user.js file for firefox.

I followed a youtube video to create a new profile to use the user script but I wanted to change the directory so I deleted it, made it anew and somehow the default profile file that i used was gone (I realised this only later). I think I had somehow overwritten it, but its weird because in my trashbin i did not find anything.

When asking me to login to sync I gave my password but it said it was wrong i realised I was using a vpn so i turned it off and then it worked, however then it asked me for a confirmation code from my email wich I also gave but it still refused saying it was wrong, which it wasn't!

After that I gave up and made a backup of my profiles and resetted my password still thinking I had my old profile file. My logins were gone and copying and pasting the login.json with the key4.db files from other profiles didnt give them back.

Luckily am still logged into my mobile app where i have my logins but there is now a warning sign to reconnect to resume syncronizing and Im afraid if i reconnect its going to delete my saved logins on the app instead of using them.

What do i do now? Is there a way to export all my data from the mobile app? Do I need to copy my logins one for one? Or can everything be resolved by reconnecting?

I had to reinstall windows 10, and then Firefox on my computer, after logging into Firefox on this fresh install (had to reset password), my saved passwords and bookmarks are not there. They still exist on my phone, and my phone is now asking for the new password to start syncing again. If I log in on my phone, will it sync the passwords there to my computer? I am worried syncing will cause the ones on my phone to disappear. Is there any way to export my passwords/bookmarks on the phone(android) to file? As a backup just in case. I logged in on an old computer thinking it would sync, even if it was out of date, but now it also shows 0 passwords saved.

According to this support page (https://support.mozilla.org/en-US/kb/sync-custom-preferences#), setting ``services.sync.prefs.dangerously_allow_arbitrary`` to True will sync all my preferences.

I have set it to true on the two devices I want to sync (2 desktops, Windows and Ubuntu). However, the preferences are not synced. For example, ``browser.compactmode.show`` keeps its default value "False" on my Ubuntu installation, despite it having the modified value "True" on my Windows installation.

I have tried pressing "Sync now", and restarting the browsers - to no avail.

Could anyone tell me what am I doing wrong?

A while ago I made a Firefox account with my Yahoo email address as the primary email, and my Outlook email address as the secondary email. Eventually I realized that I didn't need my Yahoo email account anymore, so I deleted it, forgetting that it was being used as the primary email for my Firefox account. Now I can't remove my Outlook email from my Firefox account without verifying my Yahoo email account, and I can't even delete the Firefox account since it was made under the Yahoo email account as a primary email address.

Now I can't use my Outlook email address to create a new Firefox account either.

I have followed various threads about importing my passwords without any success.

I recently swapped PCs so I exported passwords and bookmarks to disk to install on the new PC.

The bookmarks have imported ok but the passwords are in the CSV format created by Mozilla on export from the old PC and there is no option to import a CSV which seems a bit crazy.

I cannot find a way to import this data. I have tried syncing with my laptop to get the passwords but that doesn't work either.

If anyone could help me resolve this problem I would be very grateful.

Many thanks,

Mark.

My old PC still shows up on sync. I can't remove it because I took it apart when I built my current PC to reuse some parts. Is there a way to remove it from sync or am I stuck with it showing up?

XP FF68esr needed upgrade, wont sync, blue snake chasing tail. Installed Linux and FF78 (dual boot) on same machine. Deleted key4 cert9 and places carried over key3 cert8 and logins from xp68 and got everything back in order and working, except for sync. I was running FF79 on my Firestick and login to my FF account I could see the Linux machine but no sync between the two. I just installed FF120 Nightly on the Firestick to try to get used to it, but it wont sync to the Linux. It did sync to the FF79 on the Firestick however.

Seems like when I tried logging in to my old account with a password reset, I somehow created a second account with the same email.

All my bookmarks and extension set ups seem to be gone.

Never had this issue, and have been using the same firefox account for like 5 years.

my older asus laptop had a critical failure and I needed to get a new computer and to my understanding when you have had a Firefox account for as long as I have you should be able to sync your whole account to a new device to my dismay that is not the case and I have years of bookmarks and history on my account urgent fix would be appreciated.

Moving from Windows to Linux and in the process moving from Chrome to Firefox. In Linux, there seems to be an issue where Firefox isn't recognizing that I have installed Chrome. No problem, I went into Windows to do the move instead. But since the data isn't saved and you have to have an instance of Firefox running (?) to actually sync, I decided to download Firefox on my iPhone, get my passwords from Chrome, then sync to my iPhone, boot back to Linux, then sync on Linux with the data on my iPhone, and somehow in the process locked myself out of logging into Firefox on my iPhone due to how many times I've had to log in to Firefox to figure out this convoluted and broken process. People are wanting to switch to Firefox due to ad blocking support, and this is a massive barrier to entry. Can we just fix importing from a csv file?

Hello, I was reinstalling my OS, and I didn't create recovery code for my data to retrieve it after (which I found out after reinstalling my OS) on my Mozilla Firefox account, I had a lot of passwords, bookmarks and data that I need to recover, also for my full time job a lot of valuable data which I have lost now. I couldn't find any email address so I can address my concern directly, It's why I am posting here. Please help, I am so lost now. I can also provide you with any information needed, just let me know.

I would really appreciate your help, and hoping on resolving my concern in a timely manner.

I have Firefox Sync enabled in my Firefox browser on a few computers. When I logged in to Firefox Sync initially, it did sync-up my new computer with all of the saved bookmarks and history. I am not sure if any of my logins were saved). When I go to websites and login, I am prompted with the dialog to save my credentials, and I say ok, save. But the logins are not remembered. And in my about:logins page shows "no logins found". I don't care about retrieving any old logins, I just want to be able to save new ones and get the default behavior of saving logins working again.

Good evening,

I have a new laptop, from the same brand and make as my old one, both are HP pavilion with the same configuration and only 2 years in between! I have been trying on and off for weeks, to synchronise my FF browser, with all open tabs, history and bookmarks, but all to no avail. I do everything the sync instruction tells me to do, but nothing happens. I am getting desparate, because my old laptop has a problem (hardware, nothing that could prevent synchronising) and is still under warranty, but time is running out!

Will anybody help here, and how do I receive answers?
