The launch of Firefox Profiles seems to have obliterated everything in my account: bookmarks, history, open tabs, and extensions are all gone completely. I have an option to import files from another browser, but not from my own past firefox. I logged into my Mozilla account, but I didn't have any other devices so I think it was still unable to recover the data? Is there anything I can do about this, or is all of my data truly gone?

I am trying to migrate to new Android phone and I am having great difficulty with migrating the firefox profile wholesale. The adb backup method fails. The sync method will not transfer addon settings (I have extensive list of ublock origin filters). Besides I would like not to touch cloud for profile migration.

I have tried https://github.com/Rob--W/firefox-android-backup-restore but that failed epically (and I am very technical person).

I do not want to root the android (it breaks banking apps).

What now?

Really appreciate the suggestions.

I am not looking forward to re-login to all the sessions and recreate all the filters.

I need a way to recover open tabs, history and bookmarks when firefox crashed. I type placessql and session in firefox profiles folder and nothing comes up. Firefox won't open at all and I asume if I reinstall it I'll lose all previous sessions. What files I need to copy before reinstalling?

OMG someone please help me...I have used Firefox forever as my work browser. I have saved passwords to client accounts for 3rd party sites, etc. It has EVERYTHING. I updated my Mac with the latest software install today and when I opened Firefox it didn't restore my tabs. I got stuck in a loop where it would not update to the current version of Firefox. I uninstalled Firefox and re-installed it and LOST EVERYTHING. I AM FREAKING OUT because all my bookmarks are lost and I don't even know what they are - I have tried to restore bookmarks and it goes back to 2022 and 2023 and when I restore nothing happens. ANYONE SOMEONE please tell me you know how to help me find my stuff otherwise I am cooked.

I restarted Firefox today to find you have removed all my 100+ tabs, which I had arranged in folders, and replaced the vertical settings I had with Tree Style Tabs, which in the past has always run slow. I was greeted with childish graphics inviting me to set up a profile and offering me an introduction to Firefox. I have been using Firefox for years, mostly happily, until you screw up the view I had spent hours setting up. You are turning into a cheap Microsoft but with even less consideration for your users. Will you correct this or do I need to search for a new browser? Francis Shennan, LL.B Writer, journalist and law lecturer.

у меня стояла функция открытия вкладок из предыдущих сессий, но сегодня я открыл firefox сначало все вкладки были подписаны типа autoblock(или как-то так), я решил перезапустить браузер, в итоге открываю и ВСЕ вкладки исчезли, а у меня их там очень много и я точно не все вспомню, попробовал восстановить через журнал("восстановить резервную копию от" я выбрал от 21.10.2025, но она просто выдало сообщения, что текущие вкладки заменятся, на те, что в резервной копии и больше ничего не произошло) есть ли способ восстановить все вкладки не прибегая к тому, чтобы листать историю вручную?

I'm running the current version (144.0, 64-bit) on a Dell Inspiron laptop. Just now, I tried to save a bookmark, but I found that a goodly number (not all) of my bookmark folders had disappeared. When I tried to restore from a Firefox backup, I got an "Unable to process file" message. What's wrong , how do I fix it, and how do I get the missing bookmarks back?

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.

Hello, I just purchased a new desktop computer. I have passwords and bookmarks that I would like to move over to the new computer. Can this be done or do I have to manually move each item. It would be so much easier to recapture all. Thanks for you help.

I have been a Firefox user for many, many years. I started getting the Subject message: "The bookmarks and history system will not be functional" error message this evening. I started to "Fix" this error based on the Mozilla Support page. Actually, I first tried restarting my computer and that didn't correct the problem. I then noticed I could "sign off" Firefox which I thought I'd do and sign back in. I didn't notice until after the fact that my Firefox account was tied to a very old email address I once used that is no longer active "commish3@bellsouth.net". When I tried signing back into Firefox using that old email account, it said a security code would be sent to that old email address. Problem is I no longer have access to that email account.

1) Is there a way I can sign back in and have a security code sent to my current email address: tad3.dickinson@gmail.com ?

2) Can you assist with restoring my bookmarks. Again, years of building these bookmarks that I'm very dependent on.

Thanks, Tad Dickinson
