I-Firefox Community Forum

Dear Support Team,

I am writing to request assistance with an issue I encountered after a recent Firefox update. After opening the browser, an automatic updat led to making all of my bookmarks, saved passwords and website data disappear. The profile I was using had been active for over two years and contained important information that I now cannot access (it wasn't a profile I created myself, I just used the browser normally).

I have already tried several troubleshooting steps, including restoring previous profiles, checking the profile folder, and attempting to recover data from backups. Unfortunately, none of these attempts have been successful so far. The about:profiles website tells me my old profile does not exist but in my Firefox folder, there is a (profile?) folder from 2023 which contains only one file.

Could you please help me recover my previous Firefox profile or guide me through any additional methods that might allow me to restore my lost data?

Thank you very much in advance for your support.

Kind regards, Sophia

Since Firefox automatically updated (14.0.1) on my MacBook Air (2025 model) several weeks ago, the Bookmarks and History functions haven't worked. Can anyone suggest how I can fix this?

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

This morning this was at the top of my screen when I logged into my computer. "For quick access, place your bookmarks here on the bookmarks toolbar. Manage bookmarks..."

I did click on it however nothing happened or so I thought. I later go to the upper right hamburger and click on it and go to the bookmark tab only to find all my bookmarks are gone.

Can anyone tell me how to get them back since that is my quick access to my business sites? Is there a way to find them or are they just gone?

I cannot get the tab to stay out so I can take a screen shot. Sorry.

Any help will be greatly appreciated. Thank you.

Hi, All of a sudden, I lost absolutely all of my bookmarks. My PC is running Windows 11. My Firefox account was and still is logged in. At first, I thought the data loss was due to a CCleaner cleanup using their latest update. After the data was lost, I tried running another CCleaner cleanup, but this time it didn’t delete the bookmarks. So I honestly have no idea how this could have happened. These were bookmarks I had saved over many years... It’s a disaster.

After the update, a window popped up asking me to select a profile. But my profile, where all my passwords, bookmarks, etc. were, was gone. I couldn't restore my bookmarks because the only one available was from today and it`s "clean." Is there any way to restore my account data? Because everything was there: settings, bookmarks, passwords, history.

My bookmarks disappeared and I do not know why.

I have tried to restore bookmarks following the directives obtained online. Somehow this has not been successful, and this remains a giant puzzle to me.

I can see the bookmarks in Library, but I have not been successful in figuring how to transfer that listing to the Bookmarks tab at the left-sided top of the frame of the browser.

Thank you.

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
