All of my bookmarks have been disappeared with a new automatic update (9/22) and now I'm left with no bookmarks at all. My other devices were not synced because my work computer needed different links saved. Any easy options for recovery? The bookmark management tool shows no options to import bookmarks and clicking any of the restore or import options does literally nothing. This is a huge issue for work flow and is putting me out of schedule. Why would an update remove ALL bookmarks? Seems like a serious over look in function.

Hello

So a funny story happened today, I used CC cleaner to help clean my PC now I have it set up so it does not touch Mozilla in anyway yet after an update those settings got wiped and when I used the program it wiped out everything I had in Mozilla, history, saved passwords, tabs, EVERYTHING.

The last time I made a backup to my bookmarks was 6 months ago, a lot has changed since then, I tried to use the restore function however those also got wiped out, so I decided to use the old bookmarks, yet it doesn't work, for some reason it tells me that it doesn't have any bookmark data in the file yet Chrome can read and import the bookmarks from the file, if I try importing stuff from Chrome it also comes up empty, as an experiment I made a new export from Mozilla and tried to import it and got the same error. I still have 2 bookmarks and those can't be deleted no matter what I do, I kept trying to delete them however they are stuck there no matter what I try. This laptop is a new one I got on the cheap after my laptop had a problem with it's hard drive, I made the backup right before the switch.

Does anyone have any ideas about what exactly happened and keeps happening?

I have spent the last half hour searching with Google and on Muzila help – everywhere that I can possibly think of and every combination of words and every hit I get that supposedly is the instructions on how to recover sync by entering my account recovery key NEVER leads to a page where I can enter my account recovery key.

HELP!

Thanks!

Hi,

I don't come from an IT/Tech background so this has become a hassle for me. I have a "Old Firefox Data" file on the my desktop and that seems to have sub-folders with my bookmarks, sessions, logins, etc. How do I retrieve those to the new Firefox browser.

Thanks!

My bookmarks have all disappeared, and while I have tried to follow the instructions on the help page to restore them, nothing is working as it has been indicated that it should in the help instructions. I do still have my Bookmarks tab on my tool bar. When I click on it I get a pull down menu, which does have a Manage BookMarks bar. However it is not at the bottom of my pull down menu, but at the top. When I click on the Manage BookMarks bar, instead of getting an Import and Backup Button, my pull down menu disappears, so I can not select Restore to use to get dated backups.

In the same way, I can not create new Bookmarks. When I click on Bookmark Current Tab, instead of getting the white box to enter instructions, the pull down menu disappears, just as it does when I click on Manage Bookmarks. I have never had this problem with Firefox before in all the years I have used it. I have no idea what has happened.

my desktop has changed i used to have buttons to access frequently used sites appear when i open firefox and now i don't, what happened and how do i get that back, in addition all my booklmarks have disapeared how can i get it back

My laptop's motherboard is being replaced. While that process is ongoing, I'm using a spare laptop from my employer. I didn’t realize that resetting my password would delete all of my saved passwords, bookmarks, etc. Will they still be available on the laptop that’s being repaired, since it wasn’t synced with the Firefox servers?

I have years of bookmarks that have disappeared and my history is missing. Firefox opens with the tabs that were open when it shut down. I really want my bookmarks back.

Hey, So I just updated my Mozilla with the latest update and after I restarted my laptop all my bookmarks, history and favourites are gone. I didn't do any backups manually. It's few hundred important work-related links lost. What actually happened? Can I get them back? Please help.

Hello, FF 139.0.4 on MAC Sequoia15.5. Lost ALL references to bookmarks, i.e. Bookmarks Toolbar totally gone. How can/do I restore from .jsonlz4 file in bookmarkbackups. Also, will I be able to salvage my previous profile, presumably containing my older "Tabs on Bottom" work-around? Alternatively, is there a process to restore JUST Firefox from Time Machine? Appreciate any advice.

items dragged to overflow menu pop back out, will not stay there - dunno how to fix this.

Hate the "puzzle piece." Involuntarily upgraded to 115.25.0esr and it lost all my bookmarks, addons, history. How do I know which profile was the most recent, before the update added a new profile? How do I find my addons from the previous version? history?

firefox updated to 128 esr all of a sudden (i didn't click update or download for this) and when i went to open firefox, the appearance and everything changed. it looked like google chrome and none of my bookmarks and settings and layouts were there. they just DISAPPEARED. i tried googling how to to fix this and for some reason every time i search it takes me to another search engine instead of google. (this is beside the main point though). I'm so frustrated right now since all my bookmarks are gone (literally having a breakdown). I tried looking through the help articles and all of them just say to use the backup profiles or that there are bookmarkbackup files in my profile folders or that firefox would download a folder with files from the old version but none of that happened. I looked into my folders for older profiles trying to find places.sqlite files but NOTHING. there is literally NO backups or profiles dated to before July 16 2025; the day it updated (shown in screenshot) and there is NO bookmarkbackup files anywhere. i have signed in to firefox prior and had my devices synced for awhile and no issues so there should have been previous profiles and data saved onto my computer. Please help, I really need my bookmarks back!
