For some reason all of my bookmarks are gone. I have tried all the suggested fixes and it's still not working. Don't know where they went but I would sure like to have them back. Plus, now when I try to bookmark a page its not accepting it. :(

I am FURIOUS with the latest update! I put my computer on "Sleep" for a couple of hours this morning, and when I cam back to it, the screen was locked up and I had to restart my computer. When I finally came online, everything had changed! I've had multiple Windows with lots of tabs running without any problems for a LONG time, until today! Now, EVERYTHING IS GONE!

144.0.2 firefox version has an issue with bookmarks keep, they keep dissapearing & i have to use firefox fix from uninstall option to restore. unable to use email links as it requests that i close firefox window before it can open links, when i do this all bookmarks are gone & i then have to start again. I'm running win11 25h2 with all updates done both chrome & edge are not causing issues

Using firefox 144 on Kubuntu 24 LTS, on wayland, with Nvidia drivers.

I'm one of those guys with 500+ tabs. I also have a bunch of tabs open in specific containers and I recently spent a lot of time sorting most of my hundreds of tabs into a bunch of neat tab groups.

I'm not using any "sync between devices" functionnality

At some point, I open firefox like usual, and I noticed that it appears to be glitched. The rightmost tab (the last tab I had opened) seems to be working fine, but every other tab has no text, and I cannot switch to them. However, the colored line indicating that a tab is opened in a specific container still appears, it's just the tabs names that are missing. Also, firefox seems to generally not be responding, so I decide to close and reopen it.

Upon reopening, firefox restores my tabs, but I'm left with only the last tab I mentionned earlier. The "restore last session" button doesn't appear in "history". Neither "recently closed windows" nor "recently closed tabs" contain my 500+ tabs

I still have my extensions

I still have my bookmarks

I still have my base "new tab" setup, with my background image and my "pinned" websites (I don't know how it's called)

I still have my container "rules" (i.e, firefox still proposes to open specific domains with specific containers, even if I have lost old tabs that were opened in those containers)

I still have my "auto sign-ins" (i.e, I can still log into some websites without re-typing my password)

I have lost my tab groups

I'm used to losing my tabs. So I close firefox, and I go look in it's files.

The image firefox-mpris in the files still displays a youtube tab I was watching (yet this tab doesn't get restored)

I make a copy of sessionstore.jsonlz4 and sessionstore-backup, and try restoring from each backup by replacing sessionstore.jsonlz4 :

- the default sessionstore.jsonlz4 doesn't have my tabs of course

- previous.jsonlz4 has only the single last tab I mentionned earlier.

- recovery.jsonlz4 contains only 20-ish of some of the most recent tabs I had

- the "upgrade" files contains a bunch of tabs but it's from a few months ago so I'm missing the most recent stuff

Using this "scrounger" tool, I can look at what these files contain

https://www.jeffersonscher.com/ffu/scrounger.html

- sessionstore.jsonlz4 and previous.jsonlz4 both contain the single tab we talked about before (plus closed windows I don't care about)

- recovery.jsonlz4 contains exactly 25 recently opened tabs (plus closed windows I don't care about)

- upgrade.jsonlz4 contains 500+ tabs (with container ids, yay), but not the most recent ones of course (plus closed windows I don't care about)

From I saw online it looks like firefox only stores the last 25 tabs in these files, which are the last tabs I actually opened, even if more actually exist. What I really don't understand is : - Why does my upgrade.jsonlz4 file have more than 25 tabs then ? - Where are the other tabs supposed to be stored then ? the .jsonlz4 stores the last 25 tabs, yet firefox (usually) remembers all my 500+ tabs anyway, so where are they stored ?

Also, y'know, pls help me restore my stuff. Thanks.

I have no idea how my bookmarks disappeared, but I cannot locate any of them. How can I get, at least, my bookmarks from one month ago. Have an upgraded computer, new hard drives, etc. I've searched my computer, cannot find any bookmarks. Is there hope? Win `11

bold text Every other day all bookmarks and tabs disappear using Firefox the only way for them to reappear is to uninstall Firefox and then reinstall it

The 144.0.2 update lost all my bookmarks. i can not find these under the Windows Users/Roaming Data/Mozilla. etc... I tried to install the previous version and it didn't work. Also tried restoring Windows to before the update and that didn't work. Where did my bookmarks go. Annoying. you can tell corporations are getting involved with Firefox.

my firefox/mozilla updated without my knowledge. I turned the computer off and on and when it came back on it said it updated. My bookmark bar is missing along with all the drop down bookmarks I had..there was an arrow pointing down. I don't remember all of the bookmarks there were and there were lots. Some were for doctor portals. How can I get my bookmarks back I tried some online stuff but nothing works. Donna

After updating to the new version all of my open tabs & Bookmarks have disappeared with no option to recover. Additionally, all of my saved passwords for the various tabs I use daily no longer auto-generate with just a couple of clicks of the mouse.

Hello, All bookmarks disappeared after last update on Sunday 11.2.25. Is there a way to search some files and recover them? This is currently a big problem for me as all bookmark are related to our business.

I recently downloaded some Microsoft updates. When these were completed, and after restarting my computer, my Bookmarks & History were missing. I've attached a screen shot showing the error message. I've tried multiple links to recommended steps for correcting this, but nothing has worked. Do you have any suggestions?

Hello, I reinstalled Firefox and am unable to recover my bookmarks and other data. Before the re-installation, I manually backed up my data, but when I try to restore from the backup, it does not work. All my bookmarks and previous data are still missing. How can I fix this and recover my information?

Hello,

I recently installed a new add-on in Firefox — the one that allows you to create different profiles with individual names and colors in the browser.

After the installation and a subsequent restart of my MacBook Pro, my previously open session windows were not automatically restored when starting Firefox as usual. Instead, a message appeared asking whether I wanted to “restore all session windows.” I clicked “Yes,” but none of my previous windows opened.

Since then, my saved passwords and bookmarks also seem to have disappeared. I suspect that my previous profile may have been overwritten or that a new profile was created.

Could you please let me know if and how I can restore my previous sessions, bookmarks, and passwords? Is there perhaps a way to access my data through a backup or via the sessionstore.jsonlz4 file or an older Firefox profile?

Thank you very much in advance for your assistance.

Kind regards, Diamant Adler
