Firefox Community Forum

Recently my PC has died from the hardware crash. So I've bought another PC and installed Firefox. While other browsers seem to nicely sync bookmarks and history from the previous PC, Firefox didn't do that although I have been logged into my Firefox account on both PCs and I can clearly see the other PC in devices using this account. What is the reason for that?

Hello! I have an issue where there are two entries for the same device showing up when I click "Send tab to device." I've already tried logging out on this device, and the rest of my devices, and logging back in, but there are still two entries for it. I have also verified that there is only one device under this name in accounts.firefox.com.

The following content is translated using GPT machine translation. Dear Firefox team,

I encountered a problem while using the Firefox Sync service. After registering an account with one of my email addresses, I tried to log into this account on another device, but it prompted me to register again. After following the instructions and registering, I found that both Firefox accounts are associated with the same email, but they cannot be linked together. Later, I tried using a different email address, but the same issue occurred. Finally, I attempted to log in with Google, only to discover that one of the devices does not have the option to log in with Google. I suspect this might be the reason why I cannot use Sync. The Firefox version on this device is 128.02, running on Win10.

Looking forward to your response. Wishing you a pleasant day.

So, my old computer recently broke, but I luckily recovered all my files. I was re-downloading Firefox onto this computer, but my bookmarks and add-ons and stuff won't sync. When I searched for the solution to this, I saw someone having a similar-ish problem (https://support.mozilla.org/en-US/questions/1403774#answer-1563248), but they just said they had to wait awhile for it to sync. Now, I have a couple questions that I can't seem to get the answer to:

1. How long does it take to sync my data? How long did that person have to wait?

2. What if it never syncs and that person just got lucky? Is there some sort of alternate way to fix this faster?

I'd really appreciate help on this topic, but I'm not the best with computers. If anyone has had this problem, and figured it out, please let me know! I had a lot of bookmarks and a good amount of add-ons, I really would like to not lose those.

I was using Firefox for last 5-8 years and all data was saved. Few days back i was started using Linux Debian 12. i tried to login for sync but , after logging all data was erased. I tried from windows also , no data.

Hi,

I have used Firefox for a long time. I have many bookmarks, passwords etc on Firefox on my original PC.

Sadly the hard drive on my original PC has failed. I borrowed a laptop temporarily and signed into Firefox on that. My bookmarks did not transfer across and instead I had someone elses bookmarks but I wasn't too concerned as I was only borrowing the laptop.

I now have a new PC. I have restored my files from a backup external drive and I have signed into Firefox on this PC. However, all of my tabs and bookmarks have not come across. I have pressed sync but it has brought the bookmarks over from the laptop and not the bookmarks from my original PC.

How can I sync to the original PC that has all my bookmarks etc please? Or have I lost it all forever?

Thank you.

Hello, If I create custom "Recently bookmarked" like place:folder=BOOKMARKS_MENU&folder=UNFILED_BOOKMARKS&folder=TOOLBAR&queryType=1&sort=12&excludeItemIfParentHasAnnotation=livemark%2FfeedURI&maxResults=10&excludeQueries=1 and I sync my data with other device, this bookmark gets wiped on both devices. How this can be solved? Thank you

I'm sorry if this is the wrong forum, but there seems to be nothing else which seems to fit better.

I have developed an iOS App which supports Firefox Sync since about 10 years, so users of my App can directly access their firefox bookmarks. Within these years it seems that Firefox Sync has deprecated the BrowserID authentication method (which I didn't noticed because everthing worked fine) but only since recently the relevant API call "certificate/sign" is no longer working, so the authentication process will fail.

Therefore I'm looking for information how exactly I can implement the authentication now. Unfortunytely it is very hard to find reliable API documentation. Most API docs that are found seem to be heavily outdated and still list the no longer valid "certificate/sign" API call. Even the docs which already mention that Browser ID will be canceled in the future are also already outdated and half of the links lead to 404 pages.

So I would like to ask the following: Is there any definite valid up-to-date API specification for Firefox Sync and its authentication process available (suitable for third-party Apps which can not rely on Firefoxs own internal frameworks and code), and where exactly can I find it. And if a need to register an app ID/client ID and secret to be able to authenticate the App, how and where can I do this? Can anyone point me to the right direction?

Thanks for all the help...

I just got a new Mac Powerbook so I'm starting over getting all my old stuff transferred here.

I've been trying to sync my account and every time I ask for the code to be sent to my email address, it is NOT sending the code for me to use to log in!

HELP!

Hello, Is there any way to redirect firefox browser configuration (password tabs) to a specific location? I have chrome and Edge browser done this way, the configuration saves to the “profile.pb” file. It works great and without any problems,. Is there something similar in FireFox? I can't find it.

I have 2 laptops same make but different models. Both use Firefox and they are synced. Why has one a green tick but not the othr? - one image taken by snipping tool one by PRT SCR + Paint

Hiya good citizens of the internet 👋

Please help me recover my bookmarks 🥺

I've gone through every single support article on this topic and tried everything suggested and still no luck. This is my hail mary.

How I got here I needed to do a full wipe and reinstal of my macOS; this was conducted with the help of the Genuis bar. Upon reinstalling Firefox, I signed into my account and my bookmarks are all gone, records of them empty.

I should also note that nothing else ported over. No passwords, no browser extensions. Nada. The passowrds and extensions aren't a big deal. I use a 3rd-party password manager and can easily re-download the handful of extensions/widgets. But I heavily relied on bookmarks for both frequently visited sites and ones rarely-used which I knew were important for future reference. And I cannot remember 80% of them...

What else I've tried other than what's suggested in help article:

• Because I did not check to confirm which Firefox profile I've been signed into for ages and ages before doing the reset, I thought maybe I had just signed into the wrong one. I proceeded to try every other email address I have, including two from my old workplace. None of the other 5 emails had profiles created. I know this because it prompted the sign up userflow; create a password, etc.
• But I also know for a fact that the bookmarks were saved as part of a profile because I used the profile sync feature to auto-port all my bookmarks when I first got this Macbook a year and a bit ago.
• The folders where bookmark backup info is stored locally are empty... Clearly, it wasn't stored in my icloud documents (that's on me for not double-checking)
• I checked my other device (mobile phone) to see if I had firefox downloaded and was signed into the same account as the original, with the bookmarks still visible. Of course I didn't. I only use Safari on my phone 😭

""Grasping at straws: the only other things I can think of""

• Is there some way of linking my MAC address with my IP address and using those to triangulate the correct profile?
• Because my computer got wiped and nothing is saved locally, my only hope is that my bookmarks are floating around the ether. If so, I just need to figure out how to find them.

Any and all help/suggestions are massively appreciated!!

Thanks in advance,

Lauren

I have a Firefox account in order to use the sync capabilities. After a sync between desktop and phone the desktop bookmarks are on my phone in an extra folder "desktop bookmarks" and vice versa the phone bookmarks are in folder "Mobile bookmarks" in my desktop Firefox. Is this normal behaviour? I would expect them in one common folder to have a seamless synching.

Best regards, Walter
