Firefox Community Forum

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 restarted Firefox and noticed my toolbar book marks were missing. In further inspection, I noticed all my bookmarks over many years are missing. This is obviously a disaster. What happened? Is there way to recover this information?

I formatted my HDD and reinstalled windows 10 pro again on same HDD and system. After installing firefox and loggin into my account everything got synced except Bookmarks. For safety i had taken backup of my old firefox installation profile folders.

However i tried to sync and also replace bookmarks file from old to new, but none of the things are working for me. In my last installation there is no file named places.sqlite but same is created in new which is causing my bookmarks not to load.

Please note that usually all my bookmarks was automatically backed up to my account and it used to restore back again automatically without the need to take extra backup. But this time my sync was unable to restore my bookmarks.

When i am trying to click options like import bookmark from HTML or Restore Bookmark from my backup file, sadly there is no action after clicking on relevant buttons. It is not just opening the dialog box for me to select file to restore the bookmark.

I tried all options at my end but of no use. Please help as there is bug which doesnt open bookmark restore or import bookmark from other file

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

Dear Support,

today i recognize that my bookmarks are gone and i cant find any backup data or something else. First of all i restart morzilla. Then i restart my windows 11. still gone so i load a windows backup from yesterday. nothing change so i reinstall Morzilla but its still gone.

Is there anything else i can do ?

I find recovering deleted bookmarks difficult in Firefox. Typically, I am told: "on August 12 you deleted 12,540 bookmarks. Do you want to recover them all and over-write your existing bookmarks?" To which the answer is obviously, no.

What I want is a system much more similar to the Microsoft File Explorer Recycle Bin, which lists deleted files on an individual basis, so if I have deleted a file, I can see its name, the date it was deleted, and where it came from, and I can restore that particular file. Or, since we are talking bookmarks here, recover a particular bookmark.

How can I achieve that? Is it possible?

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.

I seem to have lost all of my bookmarks & i have tried to Import and backup / restore in manage bookmarks tab but all i get is a message "unable to process the backup file" plus when i tried to bookmark a web page by clicking on the Star bookmark icon nothing happens now for some reason. Was there an update as this only just started around 2 days ago

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

I have no idea why my browsing history, open tabs etc. didn't reopen after this restart. I previously had all the settings correct to reopen all windows after a restart, but now there's not even a history available.

After Firefox requested to be updated, I lost all of my bookmarks. I tried to go in and "restore" them but there are no backups to restore from. How do I get my bookmarks back?
