I was prompted to do an update today and it erased all my bookmarks. I have a saved bookmark file that is a JSON file type but it won't let me import that b/c it's not HTML. I have a lot of saved bookmarks for work and really need to get them back.

Hello,

"The bookmarks and history system will not be functional" error message has suddenly appeared in just the past couple of days on my new DELL Inspiron 15 3535 with Windows 11. I have followed the first few items on the Mozilla Support page that comes up as soon as the initial Firefox opening page appears and that has not corrected the problem.

I have tried to follow the next few steps but can't really find what it calls for because I don't understand what it's talking about. I am not of the tech generation and do not speak the tech language. Most of the terms in there I do not know what or where they are on the laptop.

Is there anybody who could help me saw through the terminology and give me some ideas on how to simply solve my problem? All I really want to do is get to where my bookmarks are hidden and put them back in place where I can use them again.

Thank you in advance for any help anybody might have.

Kind Regards, Tom B.

I went away for a week, and during that time my iMac (apple desktop) turned off. When I rebooted it last night, Firefox loaded at the start as it has for years, but ALL of my bookmarks and activity history was gone. I've been collecting those bookmarks for nineteen years, and while there's a lot of useless stuff I've collected over the years, some of it is very important.

Please help.

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

Dear Community,

Since more than a month, when firefox was updated, all my bookmarks seem to be gone,which includes a lot of valuable research made over the past few years.

I have tried all suggestions that google give me to restore my bookmarks, but as far as I understand, there are no newer ones since 2019 (nor older ones than 2018) on my computer? That's what I find in a folder called 'bookmarkbackups' with json-files. Separately I also searched for 'json' and '.jsonlz4' and found nothing after 2019. Also I searched for .html, but nothing seemed to contain bookmark directly.

When I go to manage bookmarks > 'import/export' icon in the upper bar, it suggests two options, for 'nov 13 2025', or today's date), of which none provide me with any bookmarks.

Can I somehow still recover my research?

Do I really need to backup manually?

Or need I start saving all URLs in a word-document for my new research project?...

Firefox seems to update regularly, I currently have version 145.01. (I work on a Mac 2021, with Ventura 13.7.8)

I highly appreciate any advice on this matter.

Kind regards, Maria

I would like to have a solution to reactivate all the bookmarks in the personal bar.

Best regards

3 times now, my account has completely reset, forcing me to log into everything again and not working with the key that I copy and pasted and downloaded. I would like my old data back. Why does this keep happening?

I use the Firefox browser.

While online, as I pressed a letter , Firefox closed, and its icon on the Taskbar disappeared.

After finding a Mozilla support page, and updating the browser, I found that all of my Bookmarks had disappeared.

And even worse. I tapped the 3 bars in the upper right corner to go to > Settings > Privacy Security > Saved Passwords. All of my Passwords were eliminated too. This is disastorous.

Help, I'm 71 years old.

you asked me to change my profile, choose a color and I did. But when I wanted to Firefox, all my old password and bookmarks had disappeared. I want them back if I am going to continue to use Firefox as my favorite browser.

You cant just delete all my bookmarks. Im almost in tears to have lost so much. This is beyond a joke, beyond any kind of punishment or war-crime.

How can you have the ability to delite so many bookmarks that people treasure and live with on a whim through b.s. with no apology, no meaning or reason given.

You are atrocious. This action will have caused immeasurable pain and grief to me because you suddenly decide one day you can wipe out all bookmarks on an account for no reason at all.

Shame on you, you absolutley evil harridans.

Ich habe versehentlich ein Passwort in dem Passwortordner gelöscht und benötige diese Passwort aber wieder. Wie komme ich an das Passwort wieder heran.

Vielen Dank

Здравствуйте, из-за отсутствия места на диске ВЕСЬ МОЙ БРАУЗЕР ОТКАТИЛСЯ. У меня остались папки с профилями. Но когда я их загружаю, браузер говорит, что профиль не доступен. Что мне делать? На скриншоте папки из профиля. Мне хотя бы пароли восстановить...

I recently lost all my data on my computer and after logging into my account, I couldn't retrieve my firefox data. I searched everywhere on my browser and couldn't find nothing to fix this.

Suite à la mise à jour de Firefox avec l'arrivée des nouveaux profils, j'ai perdu tout ce que j'avais enregistré sur ma session : tous mes mots de passe, mes marque-pages ainsi que les données de mon compte. Impossible de les retrouver ou de récupérer les données de mon compte initial. Je ne comprends pas ce qu'il s'est passé et surtout, j'aimerais savoir comment faire pour récupérer mes mots de passes et marques pages qui ont disparus ??
