Is 'Sync Firefox data' a way to 'back-up' your browser?

(ie: Can I retrieve all my urls even if I change my iMac (etc) to a later one?) Is 'Sync Firefox data' the way to do this?

Thank you.

Hi,

I changed my password in my Mozilla account and now I can no longer sync my firefox for android.

I scan the QR code and on my android screen proceeded normal and asking me to confirm but in my desktop I get an error.

"General application error Something went wrong. Try again later."

I also tried in safe mode with no luck.

What to do now?

Recently had to get my phone repaired and did a backup beforehand (and Firefox sync was on) but when I restored my data Firefox was empty, all tabs gone. Is there any way to get them back? And if not, any way to prevent this in the future? (I did look into my history, there are no previous tabs closed)

Thank you in advance!

I can't get open tabs to sync from my other computer. Bookmarks synced and other info but I don't see anything about tabs from other devices. I've synced both ends, both are logged in and I've selected open tabs in both. Nothing,

I have an email account blocked (jgcaller129@gmail.com) and have tried the sync tab at the top corner of my computer. It sends a message with a number to this blocked email to unblock it- how am I supposed to get an email from you on a blocked account. How do I unblock this account. I have tried several times with the same result now the icon to sync isn't there anymore. PLEASE HELP This email is very important to me. You can send a reply to an alternate email account (also linked to Firefox -jgcaller15@gmail.com).

I am attempting to think my mobile Firefox with Firefox on my new laptop and it's been following directions and there's no selection no choice to pick what it says I'm supposed to do

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.

So I reformatted my computer today, but the process allowed me to keep all my personal files. I had made a backup in my appdata for all my passwords and bookmarks like Firefox allows when you're in Manage Passwords or Manage Bookmarks. After the formatting, I sign into my Firefox account, and it Syncs almost immediately. When I go into my appdata, the profile has been overwritten by the new sync, meaning all my passwords and bookmarks are now no longer available. Is there legitimately anything I can do??

I had a Firefox debian version installed on my desktop running Ubuntu Ubuntu 24.04.3 LTS and now I just installed the latest 143.0.1 "Mozilla Firefox Flatpak" version.

How can I synchoronized or migrate all my data such as bookmarks, add-ons, open tabs, settings for syncing ?

Thanks in advance for prompt clear step by step answer.

Hi, I switched to a new phone recently, and wasn't able to outright sync all of my open tabs from the old device. It was, however letting me access them from the tab menu on my new device, so it wasn't a big deal.

Now I can't see the other phone in the tab menu, just the sync from my PC. I don't have the old phone anymore, because it was a trade in for my current device.

Is there any way to get my old tabs back? The sync must have timed out, because there was no activity for a period of time. I have Firefox synced on all of my devices.

Thank you.

Synced my new computer, received bookmark toolbar and 10 year old bookmarks from when i switched from interent explorer, but all my more recent bookmarks and bookmark folders are still missing on the new computer. Also didn't seem to transfer passwords and autofill info.

win10 last FireFox, how migrate all open tabs from one computer to another I cant find clear instruction or video, all they are old and mention about menu part which my vercion does not have.

Dear Support Team

I hope this message finds you well.

I am reaching out to report an issue I am currently facing. I recently changed my device, and upon attempting to sync my Mozilla Firefox account on the new device, I noticed that all my data—including bookmarks and saved passwords—appears to be missing.

Please note that my previous device is no longer in my possession and has been formatted, so I no longer have access to the original data.

I would greatly appreciate your assistance in recovering my data and saved logins, as many of them are not stored in any other browser.

Thank you in advance for your kind support. I look forward to your response.

Best regards,

I sync tabs with multiple devices, but I cannot get my tabs to sync with my iPad. I have tried scanning the QR code from my desktop browser. I have tried entering the password. The process never finishes on the iPad, even after the desktop browser said the process was complete.

So recently I had reinstalled windows and reformated all my drives, I am also sure that this account is my only firefox account. But when i checked the sync data it shows only 1 sync data which is today 14/3/2025. I am also sure that I had left all my sync data as default therefore it should have automatically sync. But currently I do not have access to my bookmarks, etc
