Diễn đàn hỗ trợ Firefox

It seems that the bookmarks function and history files are possibly "in use by another app". I do not understand much of this. I think it happened after an update. I tried a restore point. I deleted the Icons file as it seemed that might be an issue and they would automatically update on restart. I called Dell support, they could not fix it, neither could my smart, younger friends. So after hours of frustration, I had to install chrome, which I hate. What I want is for someone to just fix it. Its 2:30am and I need to get some sleep, I will check this tomorrow afternoon and see if I can get anywhere. Good night all!

You did a new mozilla today and my bookmarks and bookmark tool bar are gone everywhere. How do I get back to profile yesterday 2/10/2026. It deleted my settings in TOOLs, Settings. Especially in security, how I want my home screen to look. This is horrible. Help.

After the last update, I have lost all of my bookmarks!! Why? I am really upset about this. Least of all, this is not acceptable. I had some really important websites in my saved bookmarks that I needed, now I am at square-one. I am not a happy camper. Leave our settings alone.....!! Now, is there any way to get our bookmarks back? What do we do? I really need help - any help, please...... Thank you.

After updating to Firefox 147.0.3 all of my browser history (along with open tabs at the time of updating) is lost. I just updated to Windows 11 workstations (plus a couple of older Windows 10 workstations) to the current (Feb 2026) updates too. However the history data was lost before the Windows updates. I noticed that with the previous update of Firefox that saved login information was also lost. Who is doing your program updates, a chimp?

In the past when an update was done the browser would open back up with all of the previous versions session tabs in tact. But not now.

I've lost several tabs of research that was being done. Based on what has been happening, I will HAVE to change to some other browser. This is a shame as I've been a loyal Firefox user since day one. Good bye Mozilla and Firefox.

The last automatic browser update (147.0.3 (aarch64)) has wiped off all changes I made to bookmarks and passwords from the past year.

How can I go back to a previous version and recover my details?

This browser version is terrible and looks exactly like Microsoft Edge which is not intuitive at all. I don't want to set up multiple personas, Its just me and the one computer?

Please help me. Kerri

Many thanks,

Hi,

When I opened Firefox today, it asked me which profile I'd like to use. I named one Katy and then continued. Now, I can't see any of my bookmarks, none of my passwords are saved, none of my sites recognized. I've been using Firefox for years. Everything I have is saved there. I just want my old stuff back. I'm signed in on my account, but can't see another profile that I can choose. My phone still has all the passwords and bookmarks from before but I I can't see what profile I'm signed in under. Can anyone help?

Thank you!

Katy

The power went out in my area last night and When I turned my computer on this morning and opened Firefox, all my bookmarks are gone! It says the bookmark file is empty? I had many bookmarks that I use daily. How do I retrieve all my bookmarks I had in my Firefox account? Can someone help? Thank you.

Obwohl in den Einstellung automatische Wiederherstellung alter Tabs eingestellt war, wurde dies nicht durchgeführt. Da ich es zu spät gemerkt hatte, konnte ich nicht über die Chronik die alte Sitzung wiederherstellen. Was kann ich jetzt machen?

Ciao i have lost saved link and short menu links all my 143.0.3. How can i recover or where is saved CSV or else? Thanks Vladi

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.

I was using Firefox just fine during the day. My laptop switched off with Firefox still open (was simply doing sth else). When I switched my laptop back on and opened Firefox I was signed out of my account. When I signed back in all my profiles and bookmarks were gone. Is there anyway to fix this issue?

i got an update message and restarted firefox. now all my saved bookmarks and passwords for accounts has disappearred. how do i get them back? under settings, it doesn't give me option to import from previous firefox

Over the past few months, there would be occasions in which my history and bookmarks get deleted without me cleaning my browser. More recently, my tabs themselves would get deleted and today, only one of my tabs loaded upon launching my previous session. When I closed and reopened the browser, it only registered the one tab that loaded from my previous session. Is there some incompatibility with my browser and something else that might cause this?
