Diễn đàn hỗ trợ Firefox

firefox updated to 128 esr all of a sudden (i didn't click update or download for this) and when i went to open firefox, the appearance and everything changed. it looked like google chrome and none of my bookmarks and settings and layouts were there. they just DISAPPEARED. i tried googling how to to fix this and for some reason every time i search it takes me to another search engine instead of google. (this is beside the main point though). I'm so frustrated right now since all my bookmarks are gone (literally having a breakdown). I tried looking through the help articles and all of them just say to use the backup profiles or that there are bookmarkbackup files in my profile folders or that firefox would download a folder with files from the old version but none of that happened. I looked into my folders for older profiles trying to find places.sqlite files but NOTHING. there is literally NO backups or profiles dated to before July 16 2025; the day it updated (shown in screenshot) and there is NO bookmarkbackup files anywhere. i have signed in to firefox prior and had my devices synced for awhile and no issues so there should have been previous profiles and data saved onto my computer. Please help, I really need my bookmarks back!

hi firefox, today i get an update of firefox, after updating my browser my all the saved bookmarks, history and my login details are wiped out. kindly check this why is it happened and resolve this thing. the data saved in browser is important for me, help me to recover it

My bookmarks have all disappeared, and while I have tried to follow the instructions on the help page to restore them, nothing is working as it has been indicated that it should in the help instructions. I do still have my Bookmarks tab on my tool bar. When I click on it I get a pull down menu, which does have a Manage BookMarks bar. However it is not at the bottom of my pull down menu, but at the top. When I click on the Manage BookMarks bar, instead of getting an Import and Backup Button, my pull down menu disappears, so I can not select Restore to use to get dated backups.

In the same way, I can not create new Bookmarks. When I click on Bookmark Current Tab, instead of getting the white box to enter instructions, the pull down menu disappears, just as it does when I click on Manage Bookmarks. I have never had this problem with Firefox before in all the years I have used it. I have no idea what has happened.

I have a profile that causes odd behavior, within the profile, and to the OS.

Regarding the profile itself:

1. I use Multiple Tab Handler, which should allow me to move tabs on the tab bar with the mouse, but it does not (see image of proper behavior)

2. Normally, i can drag this padlock button to the desktop to create a shortcut. but now, it will not move/drag (see image 2)

3. I also have a backup profile from several months ago that has none of the above symptoms. However, If I substitute it's sessionstore.jsonlz4 file with the the one from the problematic profile, all the bad behavior mentioned above re-emerges.

I know this sounds strange, but, I also get external display issues when using the broken profile. These events are random, and manifest themselves differently, so I can't duplicate them. Essentially, these snips are examples of images from the taskbar tabs, or the clock area, suddenly superimposing themselves on the top portions of the taskbar toolbar area.

This is the view of my clock area (see next image 3)

In the following image, imagine that the portion on the left, that opens the start menu, is now hidden under what looks exactly like the clock area on the right, superimposed over it (see next image 4)

Those aberrations are removed by simply moving the mouse cursor over them, but they will continue to occur in any number of variations over any area of that top toolbar.

Is there a Session Manager that will save the session, to be later restored into that previous profile, but not also pass along the corruption?

Under Settings; Privacy and Security, my Passwords have disappeared, and at the same time all of my Bookmarks disappeared also.

While I was online this morning, all of a sudden my Mozilla tab went blank and the Firefox Icon on the bottom tray disappeared too.

All 3 problems happened at the same time.

This is a disaster for me.

Can the Passwords be restored? What in the world happened to my system?

Thank you.

Logged into my Firefox account and after restarting the browser my tabs and browser history are gone. Every file in "sessionstore-backups" is also deleted and now only has two newly created recovery files. Why did Firefox delete my desktop browser session after logging in? Can I somehow recover my old session or maybe at least my browser history?

After Firefox requested to be updated, I lost all of my bookmarks. I tried to go in and "restore" them but there are no backups to restore from. How do I get my bookmarks back?

I quit Firefox and when I restarted it it said it was a new version! It said something about restoring but I assumed it was just restoring my prior pages! DAMN! I can't even find a place to import bookmarks!

I am so angry I could chew nails!

100% of my bookmarks have disappeared. I tried backing up to older version a month ago and still no bookmarks were found. I had over 2000 bookmarks. any suggestions?? Marty

Hey, So I just updated my Mozilla with the latest update and after I restarted my laptop all my bookmarks, history and favourites are gone. I didn't do any backups manually. It's few hundred important work-related links lost. What actually happened? Can I get them back? Please help.

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

Hello,

I just closed FF (latest version) and opened it again and all my tabs are gone. I had a private FF window open, so I am guessing this is the cause.

Is there a way to get get them back?

Thanks

I don't know what you're doing but EVERYTIME I do an update lately, something goes wrong. Today after update, my STGs are affected and ALL ARE GONE. I do NOT believe this is their fault. And you put this dang auto Startpage when launching window, I did NOT ask for that. I am so pissed, how do I get them all back? I had things I was working on that were very important. What else did you add to FF that I don't know about? I don't want your updates anymore. You screwed me big time. And I don't want the extensions YOU think I should have: Google, eBay, Bing, etc. wasting my space. I'm not the only one either, seen lots of complaints.

HOW DO I GET THOSE TABS BACK??????

I'm an older pensioner, I've no wish to learn more tech stuff which is unconnected with my question. For years I've been concerned at the invasive nature of Microsoft products and so want to get rid of Win10/11 and install another OS. (I have hundreds of documents in Wordpad (.rtf) and MS are just cancelling it!) It'll probably be Linux based. So, simply I want to take my existing Firefox browser with passwords etc., to my new OS. I asked this question in Firefox and it seems Mozilla can't get over the fact that I don't want change my iOS browser to a synched up Firefox. I don't want my phone connected to my pc. Perhaps that is difficult for today's tech whizz-kids to understand but I can't help that. I'm not really technical but have had Firefox for nearly 30 years, so can anyone tell me if it's possible to copy my Firefox into a folder somewhere perhaps, and reconstitute it to work with my new OS? It certainly used to be possible. Thanks.
