CCleaner wiped out my bookmarks and their functionality. I have repaired, then uninstalled CCleaner. I have refreshed, uninstalled then reinstalled Firefox. I have logged in and out of Firefox. I have made an HTML file of bookmarks from another device in order to try to import them. Firefox bookmarks will not proceed to an upload stage. I went into setting to add the HTML of bookmarks and it said "this is not a bookmarks file." Well, Firefox made that HTML bookmarks file so I have no idea how that could be. Nothing I have tried has worked.

Dear Mozilla Support,

My name is Sizhe Xiong. Today when I launched Firefox on my Windows computer, the browser suddenly required me to select or create a new profile before continuing. I had no option to skip this step, so I created a new one.

After that, Firefox asked me to log in or register a Mozilla account. I used the same Gmail address that I’ve always used for Firefox Sync, but it seems that a new account was automatically created, and all my previous data — including bookmarks, history, saved passwords, and extensions — disappeared.

When I checked my local Profiles folder under C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles, I found several new folders created around the same time, but none of them contain my old data (all places.sqlite files are around 5120 KB).

These bookmarks and passwords are very important to me. Could you please help check if it’s possible to recover my old Firefox data, or if my previous Sync data can still be linked to my Mozilla account (using the same Gmail address)?

Thank you very much for your help.

Best regards, Sizhe Xiong

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

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.

Synced my new computer, received bookmark toolbar and 10 year old bookmarks from when i switched from interent explorer, but all my more recent bookmarks and bookmark folders are still missing on the new computer. Also didn't seem to transfer passwords and autofill info.

Firefox on my mac has been acting buggy lately. The last time I quit and reopened it, all of my windows and tabs were gone. there is no restore previous session available and the recently closed tabs and windows options are grayed out. How can I restore?

I still have not made any progress recovering my lost Firefox bookmarks. I have tried several methods with no success. The bookmark toolbar doesn't work, so I can't bookmark any more pages. I tried restarting the computer and Firefox to no avail. I am considering switching to another browser. I am using Duck Duck Go which is not as good as Firefox that I have been using for about the last 10 years. I might try Microsoft Edge or Bing or some other browser.

Sincerely

Dear Mozilla Geeks—

As practically every other Firefox user, my bookmarks evolved into a lengthy file system that uses folders to segregate categories of bookmarks.

That is, it used to have this feature.

After the last update all or most of the bookmarks (I can't tell by scrolling down the long list) are devoid of their organizing folders. This puts a great deal of information beyond easy reach. In Mozilla Help topics one is advised to click on the library icon in the toolbar ... only there is no such icon on my copy of Developer's Edition.

Can someone suggest a method or methods to recover the folders?

Some passwords have been lost as well.

Yours Sincerely,

Glen

Bookmarks in Firefox disappeared and cannot import my Bookmarks backup. I have tried to restore an older Bookmark file through /manage bookmarks/ import and backup/restore to no avail. thank you

I accidentally refreshed Firefox when I was having problems and didn't realize Refresh meant wiping everything clean. I found another thread about this, but it's 8 years old and things have changed. How do I use the "Old Firefox" folder on my desktop to restore all my bookmarks, history, etc.?

My passwords are apparently lost today after updating Firefox.

What went wrong? How could that happen? Why, Why Why?

Anyway to get them back? Are they hidden somewhere?

Anyone else suffering from this update too?

Any help or insights as to why would be greatly appreciated.

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?

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'm not sure whether i am in the correct forum. I have successfully copied to a USB stick the bookmarks from my old PC but, although I can open the html file and see them, I cannot see how to present them in the bookmarks menu. I am not recognising a simple "import" option such as I found with passwords. What am I missing

There was a issue with my computer due to which I had to reset the unit and once the reset was completed I'm unable to recover my data as its asking for 32 account recovery key, I'm unable to find that key anywhere and need help where can i find the key as there are important bookmarks which I need back.

For some reason all of a sudden my bookmarks don't show their identification icons that are associated with that web site. Those icons are to the immediate left of the site address. I used to use those colored icons as a quick reference to select the web site I wanted. Being I have MANY bookmarks, those icons to the left were a GREAT help to locating a specific bookmark.

   I could locate a bookmark by the web site icon that is shown to the left of the site address. Now that icon just shows a non colored ball with globe in it.
  Is there a way to show a earlier date of my bookmarks? Maybe that way I could see the old bookmark menu the way it used to be shown when I accessed my bookmark menu? 
   Can someone please help. Thank you.

I got a new PC and tried to sign in to my FireFox account to synchronize. But, foolishly, I ended up resetting my password! Don't know why did that, as I was able to locate my password stored elsewhere. I think this action erased all my data in my online profile & I cannot access my account data (bookmarks, user IDs & passwords) online.

Since my data was still in my old PC, I followed the directions for finding my Profile folder. I copied the folder contents to the Profile folder in the new PC. This has not worked.

I realize I wasn't supposed to copy the entire folder contents, which could be the reason why it's not working. Also, the profile folder contained a large amount of data (3 G). So, it's possible that not all files have been transferred correctly.

Please help me!

Thank you very much! Madoka
