Firefox Community Forum

When I opened Firefox, all my profile settings were back to a Default. Lost all my settings. Looked up solution on Google, couldn't find an "Old Firefox Data Folder" anywhere.

Tried the other listed "profiles" in my profiles folder, none were my most recent profile with all my settings from the past months.

How can I find the profile that was used before my update which was done 7/27/25 ish.

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??????

Hello,

Several passwords were saved by Firefox. They are only saved locally ( no sync with Mozilla account). I recently upgraded my laptop from Windows 10 to Windows 11. Since the upgrade, no password is available in "Saved Password" section. I checked my profile and I can find logins.json file ( with all encypted logins and passwords) and key4.db file. I suppose my passwords cannot be decrypted as they were encrypted with Windows 10.

Is there a way to recover my passwords?

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

I was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

Hello! Recently I experienced some massive issues with my pc and it needed service, it was uncovered that my drives crashed and the data is gone, they tried to restore it but its all corrupted therefore I cant get my bookmarks back in file form.

My account was synched so all my bookmarks surely are in cloud, today I got the pc back from repair, but my account only syncs bookmarks from the spare pc I used during the repair time and those bookmarks are outdated by two years, the pc which went under repair does pop up in the logged in devices list, so all the bookmarks that were there gotta be stored in the cloud, can you help me recover them?

Best regards Sarah

There was an update today on my PC laptop, I think from FireFox. After the restart, my bookmarks have all disappeared. The instructions to restore them are useless. I go through Menu/Bookmarks/Manage Bookmarks/Import and Backup/Restore/Choose File. THERE ARE NO FILES TO CHOOSE FROM. According to the instructions, there should be some dated entries. Nada.

I tried the Troubleshooting blahblah and that was equally useless.

I'm panicking that I've lost years of carefully organized bookmarks.

When my Firefox crashed today, I chose to restore it rather than troubleshoot. When it was done, my bookmarks icon had disappeared. Yet when I go to the individual websites, I can see that each one is still bookmarked. How can I restore the icon that used to be in the toolbar at top? Thank you for any help you can give. I have been using Firefox for many years now and this is the first time I encountered this problem.

Since updating Firefox on June 30, 2025 on my Dell desktop computer that runs Windows 10, most of my bookmarks are no longer visible. Only four of my bookmark folders are visible and most of their contents have disappeared.

However, 1) my uncategorized bookmarks - those in "other bookmarks" are still visible, and 2) If I go to "Manage bookmarks" and do a search, I can find all of my bookmarks including those that are no longer visible.

In addition, I can no longer add or delete bookmarks. It looks like I can do add a bookmark and it will let me go through the steps of adding a book mark - it even says I can put it in all my old folders that are otherwise no longer visible. But one I complete the process the bookmark does not show up.

I have read multiple Firefox Help articles about disappearing bookmarks and have taken all the steps suggested including: - Attempted to restore backups of bookmarks - didn't work. It shows me the multiple old backups but when I try to restore one I get the message "Unable to process the backup file". I have tried it with at least four of the old backup files - all without success. - cleared cache - did troubleshooting mode - refreshed Firefox - uninstalled and reinstalled Firefox - looked to see if I had a different profile other than my default profile that I could switch to. I do not see another profile.

Nothing has helped. Any suggestions would be greatly appreciated.

Thanks

My Win10 & Win11 pc's updated to this version and they all have the same problem: The bookmarks have disappeared. Including my pinned bookmarks on FF's opening page.

I also just noticed that there are no "toolbar items".

So I asked a question yesterday with the same problem but since then I've done a lot of my own research & what-not so I'm hoping I'm little more educated on what to do, however I'm just not fully understanding what I'm doing wrong, unfortunately.

So a run down of what happened yesterday. I was told by a microsoft guy to do a factory reset but select the option to keep my files. Which I did. I thought because I have a Firefox account my passwords will be uneffected. I did the reset & came back, downloaded firefox for their website, went to sign in & of course, I forgot my password for that, I hit forgot password & I was told to insert a 32 key code. I was never once given a code, I've had my account for yeeeears. I had to forgo entering the code & yup, everything has been wiped.

Since then in my research, I've heard many people talking about C:/Windows.old/users/kelsi/AppData/roaming/mozilla/firefox/profiles - I have this in my folders. Inside that there's also logins & logins-backup (JSON files) & key4 file. When I open up the logins into my notepad app, I see all my sites that I have passwords for (encrypted) so they are there! I then also have C:/Users/kelsi/AppData/roaming/mozilla/firefox/profiles/profiles (there's two folders labelled profiles). I was speaking to a few users online who said that I've to copy & paste the C:/Windows.old(...)profiles onto the C:/Users (...)/profiles & then start up firefox again. I did all that, opened up firefox again but nothing. However in the c:/users folder upto & into the profiles folder, it's got the key4, logins, logins-backup there. When I open the logins file on notepad, all my encrypted passwords are now also in the c:/users(...) profiles section.

So I'm just wondering what to do now. I feel like I've gone crazy trying to figure this out. I've got a lot of resources to use, spoke to so many people but I seem to have hit a deadend. I'm a complete beginner with all of this, I only use my laptop for Firefox, so I really don't know much about the ins & outs of anything else. I am hoping this makes sense to someone & can point me in the right direction of either where to go next or what I've done wrong (I can't emphasis enough how much of a beginner I am, so please make it easy to understand) Thank you in advance.

Hi, I hope maybe there might be a ray of hope here but I royally screwed up. Like BIG time. I was having issues with my windows laptop & the microsoft guy said to do a factory reset but select the option to keep my files & everything will be fine. Which I did. I did the reset & logged into my Firefox, only to find that NONE of my passwards had saved. It had asked for a 32 Key code but I've had this account for years & years & years and have never once been given a 32 key code. I thought maybe it was an option for future password reset so just clicked on 'next'. Well my bad, that was the dumbest thing I've ever done because all my passwords have been wiped & I've only managed to recover a tiny handful but most of them seem to be gone for good. Is there any hope of recovering? I thought because I had a Firefox account then that would be that, everything would be saved in the that account. Really wish I knew about the code thing, I wouldn't set one up if I knew. I think my biggest lesson from this is don't full trust the Microsoft guy if he makes it sound super easy & fuss free!
