Diễn đàn hỗ trợ Firefox

This has happened several times in the last 4 months or so, it had never happened prior to that and I've used Firefox for years. It now occurs when I open Firefox after my computer has either been shutdown, or the computer does a restart. I am signed in to my Mozilla account.

My computer died when I had many tabs open. Some of them were important. I cannot get back into my old computer to recover them from there. It appears that sync was not enabled. Is there any way I can get them on my new computer?

I can actually see a list of the tabs. When I hit the hamburger icon, the first item is my account. At the bottom of my account is a heading “[username] on [device name]”. Underneath is a list of all my tabs from my last computer.

But I have to open them one by one. Is there any way to batch open these pages?

I have used firefox as my brouser on my PC for years with all my bookmarks and passwords. Now without my old computer, how do I restore all my account passwords and bookmarks as it was before.? I am using windows 11 on a Dell desktop PC. Please help. I am not a computer genius. Is there a phone number to call for live help.

It seems to me that recovery from backup only allows one to recover ALL bookmarks. But maybe one wants to recover only one folder, or only a few folders. Can that be done? If so, how?

Hey guys, My friend got on my pc and shut it off without me looking and somehow when i opened it back up all my tabs(couple hundred) distributed between 3 windows were lost. I've tried all the usual recovery options by doing previous or session restore, its not popping up in recently closed windows as well, where i usually recover my sessions from if it does go wrong. Is there any other way where this data may be stored, to recover a session from 31st Dec 2025.

Would greatly appreciate any help :D

I'm not sure what happened. I restarted my laptop and when I tried jumping onto Firefox it didn't have my normal accounts on it they were gone and I had to make a new one which means all of my bookmarks are gone, none of my accounts are logged in I am freaking out! What happened?!?!

Wieczorem po zakońcaeniu korzystania z przeglądarki jak zwykle wyłączyłam. Następnego dnia postanowiłam go uruchomić i nagle wyskoczyło mi jakieś okienko profilu co zignorowałam bo dla mnie ta funkcja ejst bezcelowa. Przeglądarka się odpaliła ale już bez moich danych - rozszerzeń, historii, a co najważniejsze bez zakładek! Konto mam zalogowane ale nie potrafi mi tego jakoś przywrócić.

Hi,

I am not a tech savy person. My firefox crashed on my laptop. Now all my book marks are gone. But the book marks are there on my iPhone. Can somebody please please help me to restore?

I've spent more than half of today trying---once again, after you must have done some "update"---to restore my many bookmarks, including the bookmarks menu. I HATE THIS FAR TOO FREQUENT WASTE OF MY TIME!!!!!!

Have tried all of your "tips" online for fixing this and this time NOTHING works. Damn it---fix this and quit doing this to us!! Have rebooted -- in Safe Mode -- several times. Can't find anything in a profile that gives you permission to screw me over like this so much.

Import from my html file gets no response. Restore with my JSON file gets no response.

Please quit wasting my time every couple months!!!!!! This is soooooo fgrustrating.

Where do I input my recovery Key to get my account back? I recently had to get a new mother board and hard drive on my laptop. In the process, it wiped out my Firefox. I have reinstalled Firefox and have my previous Recovery Key to get my bookmarks passwords but can not locate where to enter the recovery key to do this. All I can seem to find is how to create a recovery key, not where to enter an already existing recovery key. Please help.

My primary firefox/google profile vanished along with all bookmarks. Recovery history only shows bookmark from secondary account that is under a different email.

How to I restore the bookmarks (years worth!) from my primary profile?

I had around 3000 tabs open I closed the browser completely today. Normally when I reopen firefox all those tabs were appearing still. This time none of the tabs restored I can see tabs in history part namede 19.01.2026 although not all my tabs are there. When ever I try to reload them from the restore history part; firefox doesnt reply and doesnt take the command.

Hi. In the process of reinstalling my laptop (W11) I synchronized my Firefox, as I have done some many times before. No, this time, it seems that all my bookmarks and passwords have disappeared from the sync service...

Is there any way to get them back, now that my laptop has been reinstalled, from scratch?
