Diễn đàn hỗ trợ Firefox

Recently, Firefox updated and ask me to setup a profile, which I have not yet done since importing my data from google chrome in 2025. After skipping the setup, Firefox then deleted all my data and it has since been irecoverable. I have already checked the box last update that specifically said to not ask me again for setting up my profile. After the recent update, the question popped up again and now I cannot recover my original profile, all my browsing history, all my browser-saved data, and all my cookies and logins

Hi,

I just updated to the latest version of Mozilla FireFox and my bookmarks dissappeard.

All are gone, I wonder how I can get them back?

Many thanks,

I had bookmarks and backgrounds and everything saved on my browser. My mac book died and now when i open it everything reset. I didn't have any profiles or sync on but why did everything reset. And am i able to get what I had back.

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.

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?

with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

and

Context: So, I needed to get into Pear Assessment for school (I use my personal computer for school too) And I couldn't get into my Practice Test, so my mom suggested that I delete my history in an attempt to get in. So then I deleted it also thinking it might have a chance at working. But it didn't, and now I deleted my personal history for nothing. Please help me. Thank you.

(It is my first time using this website. I am a child, so I'm not sure how to answer everything in means of details. Also I put this on "browse" because, you know, browsing history. But I do know that my MacBook is a: ["macOS High Sierra Version-10.13.6 MacBook Air-(13-inch, 2017) Processor-1.8 GHz Intel Core i5 Memory-8 GB 1600 MHz DDR3" Hope this info helps you])

Bye, and have a good rest of your day. And don't let anyone tell you otherwise!

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?

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.

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.

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?!?!

I had a ton of saved tabs and groupings of tabs. I closed what I thought was my only open Firefox window then downloaded and installed the most recent Windows update. When I rebooted, I did not realize I had left a Firefox window open with a single tab. That Firefox became my default and I lost all the tabs I had. Is there any way to get those tabs back? The tabs I had yesterday, 1/22/2026 are the ones I need.
