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

I have Firefox on Windows desktop and on my android phone. I have logged into both. When I click on "tabs from other devices" I only see tabs from another PC I use.

I tried logging out of Firefox Android and using the desktop browser's "connect another device" link to log back into it, but it still doesn't appear as a device. What am I missing?

EDIT: Ok now Android tabs are showing up, but not all of them. Seems to cut off after about 40. Anyway to get Firefox Desktop to show all Android tabs?

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 was logged out of both computers so when I signed back in to sync my desktop to my laptop, it would not sync my rows that I have on my desktop I ended up changing two bookmarks on the homepage Rows when I was signed out but they would not change on my laptop when I was signed back in I had to do it manually, but if I stay signed in, I'm sure that it will change but how fast is it supposed to do that because I waited at least five minutes and nothing changed. I also clicked on my icon and clicked on sync now, but nothing changed.

I had to reset my computer. Then when tried to sync my mozilla data. Maybe because I had to change my password due it was in my computer's passwords key (I didn't memorize it, my bad). I'm worry because I'm a ebay's seller and all the bookmarks are so important for my store due there are info of my items future sales. So I'm so sad and desperate. I'll GREATLY appreciate your help, please. Thank you so much for time.

I have 'synced' my old phone. Now I have new phone with a Firefox that I used for setup, which has a few open tabs and maybe a couple b9kmarks. I want to 'restore' everything fromthe old Firefox to the new. What happens if I 'sync'?

My guess is 'sync'ing the new firefox merely backs up its current state...

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?

I have used Firefox bookmarks via sync for 20 years!! My previous computer is bricked and cannot be accessed. I have a fancy sync code but when I download Firefox on my phone or new computer, it’s like I’m a first time user. It offers me a new sync code but won’t allow me to use what I have. Are my files recoverable? Can I wipe from my old machine too?

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?
