Firefox Community Forum

I'm trying to restore bookmarks after latest update. I get to the Import and Backup dropdown and pick Restore. there is nothing listed. I can go into my "C" Drive and find my "bookmarkbackups" folder and see the files. How can I get it reinstalled?

My mac froze, force quit did not work, unplugged it, turned it back on, all bookmarks were gone and not able to add new ones. Would like to restore old bookmarks and add new ones.

it looks like mozillo ambushed me, did away with all of my setting I spent years getting where I wanted them and left a folder called Old firefox data on my desk top. how do I make it look and act like the old firefox? I do not want the side bar I want the icons on the same line as the search bar. I want firefox to be my default everything like it was. I hate edge but it seams the only way i could get rid of it was to uninsal firefox and reintal this new pink firefox home page. I want my home page to be foxnews. how do I restore everything from teh old data filke to this confusing new page?

My Bookmarks are missing. I see backups under the profile/bookmarkbackups folder but when I manage bookmarks, they are not in the restore dropdown. I have followed the steps to delete the places.sqlite but when I reopen firefox, I do not see the bookmarks have been restored. I thought it might have been related to Norton Utilities so I renewed a subscription but no luck. I also have a json file with my bookmarks but I cannot choose it from Manage Bookmarks, either

Hello,

This morning Firefox stopped loading new tabs, which usually means it is due for an update and restart. On my work computer, updates are managed by my organization, so I cannot prompt it to check for updates directly, but rather can just restart the application and it updates once closed. Today when I closed the window then clicked the shortcut to reopen, it notified me the exe file had been removed and prompted me to open the Windows store and reinstall, which I did. I have no indication as to why it uninstalled. All of my bookmarks and other history appear to have been wiped.

I have been trying on the support site to see if this data is recoverable, but nothing has panned out so far.

I have used Firefox as my primary browser for almost twenty years and frequently encourage friends and family to use it if they don't already. I have never experienced anything like this before. I am hopeful somebody will be able to assist me where reading through support center options hasn't yet, but if this is not resolvable, I'm done- the crash helpfully wiped everything clean, after all.

Any suggestions or response is greatly appreciated. Best, Z

Firefox updated automatically. No bookmarks or history??? I cannot find anything. This is my old Windows 10 computer. Have bookmarks on Windows 11 computer. Afraid of updates. any help?

Hi, Today 8-7-25 Mozilla automatically upgraded to version 141.0.3. Now all of my bookmarks are gone. I can't find them on my pc. There are two profiles listed in the profile section. Neither seem to have my bookmarks. I have a lot of bookmarks and some are very needed. Please help me recover all of my bookmarks. Thank you, Geo

Several times now I've closed firefox while having the open previous windows and tabs on startup on only for all my tabs to have been closed (with this time in particular being annoying due to losing tabs that I needed to have the specific link for). Is there any way to restore tabs lost in this way?

I AM HAVING THE SAME PROBLEM AGAIN, I HATE HAVING EVERY SINGLE ONE OF MY TABS DISAPPEAR WHENEVER IT CLOSES WEIRDLY AND I LITERALLY CANT RECOVER ANYTHING, AND IT GIVES ME SOMETHING NEW, WHAT THE HELL EVEN IS THIS FIRST FILE, I HAVE NEVER GOTTEN THAT JSONLZ4 FILE E V E R!!! AND WHEN I TRIED TO DO THE SAME METHOD OF REPLACING THE FILES WITH ONE OF THE OLD RECOVERY FILES LIKE IN MY OLD QUESTION, IT DOESNT FUCKING WORK, SORRY TO SWEAR BUT ITS UTTERLY RIDICULOUS DUDE!!!

My bookmarks have stopped working. When I went to Edit Bookmark I found they are all empty. I can create a new bookmark as usual, but I have over 300 bookmarks that no long function that are very important to my work. Is there any way I can possibly restore them, as my work depends on them?

I am trying to recover a FireFox session from a backup of my C:\ drive from a few months ago, but I am blocked by "access denied". No matter what I have tried, access is always denied. I an using FireFox version 149.0 on Windows 10, and am trying to manually make the substitution in the folder C:\Users\...profiles\318tzbcg.default-release\sessionstore-backups.

I have tried the substitution with FireFox totally shut down (checked in Process Explorer) and even after a reboot. I am blocked from copying any of the current files to another folder or to rename them (as a precursor to (hopefully) replacing them), much less over-copying them with files from my drive backup.

I have tried from an this with CMD (run as administer) in my normal user account (which has admin privileges anyway) and with an actual Administrator account. In my User account I have verified for the properties of the Profile and sessionstore-backups folders that all of the accesses are ticked as allowed for write and read (except Special Access is not ticked). The section with the tick boxes is greyed-out (with those boxes checked), and I cannot untick any of them or put a tick on Special Access.

(I am writing this from a different machine, so have not clicked the Share Data button (troubleshooting information) on this submission form, but can provide that later from that machine,)

What can I do to get the needed access (permissions) to substitute a recovered sessionstore.jsonlz4, recovery.json4lz or previous.json4lz file?

Firefuxxed was refusing to open new tabs so I shut it down and restarted it (always fixes it) and all my pinned and open tabs were gone with no way to recover them, it took me half an hour to manually restore the pinned ones one by one but not all of them as I cannot remember all of them let alone all the open tabs I had (hours of research gone down the toilet).

There should be a way to backup and restore pinned and open tabs so this doesn't happen, the history option does nothing.

OS: Linux Mint 22 fresh install from a week ago Previous version of Firefuxxed updated after this shamossel.

Dear Mozilla Support,

My name is Sizhe Xiong. Today when I launched Firefox on my Windows computer, the browser suddenly required me to select or create a new profile before continuing. I had no option to skip this step, so I created a new one.

After that, Firefox asked me to log in or register a Mozilla account. I used the same Gmail address that I’ve always used for Firefox Sync, but it seems that a new account was automatically created, and all my previous data — including bookmarks, history, saved passwords, and extensions — disappeared.

When I checked my local Profiles folder under C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles, I found several new folders created around the same time, but none of them contain my old data (all places.sqlite files are around 5120 KB).

These bookmarks and passwords are very important to me. Could you please help check if it’s possible to recover my old Firefox data, or if my previous Sync data can still be linked to my Mozilla account (using the same Gmail address)?

Thank you very much for your help.

Best regards, Sizhe Xiong

100% of my bookmarks have disappeared. I tried backing up to older version a month ago and still no bookmarks were found. I had over 2000 bookmarks. any suggestions?? Marty
