I appear to have my bookmarks duplicated. Bookmark Menu list of bookmarks, bookmark 1

                                                           bookmark 2
                                                           bookmark 3 etc
                                                           ........
                                                           bookmark 1
                                                           bookmark 2
                                                           bookmark 3 etc

At a glance, the repeated bookmarks are the same, but I could have filed a new bookmark in either set. What can I do to stop these duplicates?

i re-installed my windows, installed firefox, and it automatically re-synced everything, a few days later, windows had an issue so i had to install windows again, but this time, when i installed firefox, i logged in, and after finishing syncing nothing was there, everything is gone, that being said, it's only form the desktop browser, i still have all my bookmarks and passwords on my phone's firefox, but they wont sync into the desktop one i cant find an option to export the phone ones into a file to import in the desktop app, i need help

Hi, my PC had some hardware problem and al its data was wiped as procedure, so i had to install everything from zero, this includes Firefox, and when i did so i did the same as usual, download it, open it and log in to sync my data, but there seems to be a problem, all my data is gone, it says its synced and i try to sync it many times, no bookmarks, no extensions, no passwords, nothing, this is my only account too. tried to look up solutions online and saw people talk about 'old Firefox data' folder that can appear on the desktop but nothing for me, tried to go to about:profiles and see what profiles i had and switch to see if its in any or if the folder appears but still nothing, i don't seem to find a solution, i only got the PC back at the end of December last year, and its as far as i can see my Firefox activity here, but I've always used this account and I've synced in multiple PC's with no problem i don't understand what is happening now. thank you

his is a new issue starting from FF 148.0.3

In FF on my PC I create a folder in the bookmarks toolbar for that day's research. I drag page URLs into there to bookmark sites/pages for follow up reading.

As extpected the shortcuts have the site's icons.

Open FF on my Macbook at home and since this verion, no favionns until I open the respective pages.

This is new. All other sync seems fine.

This is a new issue starting from FF 148.0.3 On my Windows desktop I create a folder, Research. I drag URLs into it for follow up, and on PC as extpected the shortcuts have the site's icons.

Bug report I suppose. Non trivial.

Installing firefox on my new device: Not all of my bookmarks are uploading from firefox on my other device.

It uploads a really old version of the tool bar even tough it shows in the HTML folder I am importing from my other device that the updated links are in the tool bar category.

I am signed in on all my devices. Yet nothing has synced since October 2025. So none of the books marks from my laptop display on my desktop in bookmark folder. The folders don't even match what is on my laptop. How do I fix and how do I prevent in the future?

Everything is gone, I have had to reinstall windows 4 times in the last week with a new PC and now all my sync data is gone...Chrome remembers everything fine and Mozilla did remember everything until this install and now its not syncing anything.

If this stuff is gone so am I.

Have tried logging in with my google account, tried logging in with Moz account, tried sync button over and over tried restarting, tried uninstalling and reinstalling and manually deleting all the folders STILL NO SYNC DATA AT ALL.......

Hello,

I'm unable to find the sync bookmarks,

I'm trying for a long time, in my iPhone and MacBook, both Apps are the latest, using the same email and the Bookmarks do not show in any of the devises.

Can you please help me?

I tried linking my unlinked profile to my email, I made a typographical error there and when I tried to undo it, Mozilla says this profile is already linked to that email. Mind you, I have not even entered a password or verified that email address yet. I cannot even remove that email from the profile now, even if I do and try to re-sign, the accounts page says I am already synced to the typo email.

I did a clean install of Windows and downloaded Firefox, but after signing in and pressing sync none of my old bookmarks or anything is showing up. Is it gone now? I did not have Firefox on any other device.

Description: Multiple prior failed attempts. Clean setup, issue persists.

Android: Samsung Galaxy Tab A8 (SM-X200), Firefox 147.0.2 (~1500 bookmarks) - Old account deleted, cache cleared, restart. New account + Sync enabled.

Windows 11: Huawei MateBook D15, Firefox 147.0.2 - Old profile/account removed. Same new account + Sync enabled. - 30+ min wait: NO SYNC. Logs clean, Places DB verified OK.

Suspected: Android bookmarks not uploading to Sync servers. Questions: - How to verify/force upload from Android to Mozilla servers? - Tools to export/backup Android Firefox bookmarks (no HTML export)?

Thanks for help! swann

With Firefox Android on my tablet, bookmarks are not syncing that i see when logged into my Firefox account on other devices. I tried logging out and in to my Firefox accont and also unchecking and checking the "sync bookmarks" box. Firefox Android says "bookmarks are now synced". But they aren't!

After a few days of having no internet connection, my account was disconnected from my PC and saved passwords disappeared. After signing in to my account again and syncing, lost passwords were not recovered. I need help to recover them.

Sync is corrupting my bookmarks.

This is affecting Firefox on multiple Windows computers, and multiple Apple devices (phone and tablets).

Only partial data is available. The bookmark “tree” structure is complete, but the bookmarks are only partially populated (only about 15%, and it appears these are newer items).

I did not change/edit any bookmarks or Firefox settings. This did not occur after a Firefox or OS update (it has simultaneously affected Windows 11, Windows 10, iOS 26.2.1, and iPadOS 26.2.1 devices, Firefox 147.0.2 on the PCs, iOS 147.2.1).

One one computer I momentarily saw all the bookmarks (machine version) disappear as Firefox synced the corrupted version to that computer.

I know I can restore the bookmarks (at least temporarily, until Sync may re-corrupt them). What is causing sync to change MY information?

i recently switched to zorin os from windows 11 and i noticed my firefox data was gone (despite being signed in + syncing my passwords) could it be my wifi? an unrecognized device? its the same laptop + network so idk what

My bookmarks bar, etc have will not synced with my Firefox even though I ran "sync" several times. I haven't used this laptop in quite awhile, so I had to log in and sync. Also in my themes, a certain creator "MaDonna" has error messages on all of them" Cabin in the Mountains (and all others by her) by MaDonna could not be verified for use in Firefox and has been disabled." In my extensions page, I get the same error message. I am beyond frustrated, I'm also very computer literate, but this mess has me baffled and frustrated :(

I have a Windows Surface Pro 8 and when I set it up, I had no issues with the Syncing or Add ons/Themes/Extensions, everything synced just fine. I have Theme categories set up, and that's not even on the Themes page. I have logged into all of my Firefox/Mozilla accounts. Can anyone help?
