Firefox Community Forum

I had to erase my laptop and am in the process of resetting it up. I used firefox prior and am trying to see if it is possible to restore all my previous bookmarks etc. I was told it automatically backed them up.

Hello, yesterday my 2025 Macbook restarted on it's own and my Firefox browser restarted too, and while it brought me back to all the tabs I had open, every single one of my bookmarks has disappeared. I only have one profile. All my extensions are working properly. The bookmarks sidebar and toolbar are both completely wiped clean. I've tried to go through the backup and restore options provided in this community previously, but going into my library and clicking 'backup' or 'restore' has done nothing. How can I recover my bookmarks? I had been saving small business links for years that are now just gone for seemingly no reason.

Upon restarting my laptop earlier today, I realized that ALL my Firefox bookmarks have disappeared into thin air. Gone (or, rather, "empty") is my bookmarks toolbar, and my bookmark menu, and everything else. What to do? Thank you.

and how do I fix it so I can restore previous sessions I accidentally close? I accidentally deleted all prior data from whatever version of Firefox I was using the other day (I didn't have a profile as far as I'm aware) removing all saved passwords, bookmarks, history, and apparently the Restore function.

My bookmarks have disappeared. I have followed the steps to restore them under the FAQ, but at Step 2 ("In the Library window, click the import-export-arrows button and then select Restore"), when I click Restore, no list of backups appears from which to select the one I want to restore. I have been using Firefox for years and have loads of useful bookmarks. How can I get them back?

Hi,

I just updated to the latest version of Mozilla FireFox and my bookmarks dissappeard.

All are gone, I wonder how I can get them back?

Many thanks,

I lost all of my bookmarks and saved passwords with the latest update. How can I revert back to my old version so I can at least save them to a file to be imported?

My Firefox book marks have disappeared. The toolbar is open but has nothing to display.

I've gone to my Firefox Library window, but the entire page is blank. The table gives no entries for Name, Tags, or Location. Lines below (Name, URL, Location, Tags, and Keyword) are empty.

Searching my MacBook Air I found my Firefox Profile folder. In it there's a folder ending in "default-release". That folder contains a folder called "bookmarkbackups" containing files with titles indicating recent backups.

How can I restore my booksmarks?

When browsing between two screen, all my saved Firefox tabs disappeared. I have restarted my computer but they do not reload. I really need them (and have not accessed some of them in several weeks so it will be very hard to recover from history.) WHY did they go away and I do I restore them?

I had an unusual system crash, and when I restarted Firefox, the History > Restore Previous Session feature was grayed out. Due to the nature of my work, I had a large quantity of tabs open at the time of the crash (please don't judge). I then backed up the contents of the \Library\Application Support\Firefox\Profiles\[session].default\sessionstore-backups\ folder, but unfortunately not the full Profiles folder content. The file recovery.baklz4 does seem to contain my open session info (I can see a recent link in it). Based on web advice, I then tried restarting Firefox, but that didn't solve my issue. I also tried copying in sessionstore-backups files, without success. I then tried the "Session History Scrounger" web application to try and recover links from the contents of recovery.baklz4 because that worked for me in a prior crash years ago, but it doesn't seem to work properly anymore (it only retrieved 4 web pages). Appreciate any guidance as to how I can use my backed up sessionstore-backup files to re-enable Restore Previous Session, or alternatively to scrounge the links that were open at the time of the crash. Greatly appreciate your help! (Please do not suggest using "Show All History"... I have no plans to sort through a dump truck of rice with a pair of tweezers.)
