Several times now I've closed firefox while having the open previous windows and tabs on startup on only for all my tabs to have been closed (with this time in particular being annoying due to losing tabs that I needed to have the specific link for). Is there any way to restore tabs lost in this way?

I think that this recent update removed all of my tabs and tab windows, it has done this before and I don't understand why, I have the old update session file still (The 11/11/2025 One) and I tried to use that one to bring the tabs back by putting the file in the sessionstore-backup folder with no other file in it, but they didn't come back. I am genuinely confused as to why it doesn't work, I have renamed and deleted sessionstore.jsonzl4 files but it still comes up as a new session.

Today I opened Mozilla at my laptop. It malfunctioned (videos froze, pages did not fully download), so I closed the window and after a couple of seconds I reopened it. My previous session was gone. I read your articles regarding this issue, did what was described there, but nothing has changes. I lost everything! Job videos, hobby pages - everything! A couple of pages can be restored via history, but that's it! I didn't do anything special before closing the window!

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?

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.

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.

I opened FF this afternoon and it op0end like a new first time install- asking about setting up some damn profiles and showing news, AI, weather and crap I do not want or use..

I can not seem to restore it. All bookmarks, PW, menu bars and links are now gone.

Siguiendo sus instrucciones facilitadas, he conseguido recuperar la carpeta de mi perfil anterior pero no se qué hacer con ella para que aparezcan los marcadores de siempre en la aplicación, cómo lograrlo Gracias

Can Firefox do anything to recover all of the downloads I'd saved until I accidentally had CCleaner erase everything? I don't know what else was deleted, but getting them back would be a big help.

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

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.?

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.

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?

The initial problem I was dealing with was FF kept directing me to Youtube every time I clicked on a NORMAL link in my google search. 🤷‍♀️ I tried several different links but same result....Youtube again!

This is where I went down the rabbit hole. 🙄 My first step was to get some help with my Firefox browser for this 'redirecting' issue. Under the help heading, "More Troubleshooting Information" I found "Give Firefox a Tune-Up using Refresh". Hmmm, maybe this will fix the issue?? I carefully read the following before proceeding....

"Start fresh to fix performance issues. This will remove your extensions and customizations. You WON'T LOSE ESSENTIAL INFORMATION LIKE BOOKMARKS AND PASSWORDS."

WRONG!!! MISLEADING!!! LIES LIES LIES!!! 😡😤😡

I lost almost ALL of my saved bookmarks except for TEN (the most recently used) that still remained after the refresh was completed! I literally lost over a hundred of them that I had accumulated while using Firefox for so many years!! 😲😣🤦‍♀️ 21 different folders, Home, Travel, Shopping, Banking etc, each containing 10-30 OR MORE bookmarks to sites I need to SAVE to be able to revisit later when needed. ALL GONE!!! 😡😤

I have been loyally using ONLY Firefox as my browser for 2 decades!! Now the only thing I can say about Firefox is a whole lot of curse words!!

WHY WOULD FIREFOX INCLUDE SUCH A #$@&! STATEMENT??? "You won't lose essential information like Bookmarks and Passwords"......YES YOU WILL!!!

This NEEDS TO BE REMOVED!!

Why not be an honest and reliable browser?? Include information that if you perform a refresh, you WILL lose these essentials but you might possibly be able to recover them from hidden files somewhere, but you won't easily know where to find them!! 😉

The next time I have ANY issues using Firefox I won't be 'refreshing' nothing at all!! I won't troubleshoot NOTHING!! I will just copy and save all of my bookmarks and SWITCH TO GOOGLE CHROME!! 👍

Absolutely furious. My bookmarks have completely disappeared and none of your suggested 'articles' is any help at all. I certainly won't be using Mozilla any more if you can't tell me how to rectify this.
