Forum der Gemeinschaft Firefox

I've been searching for three days now for a solution that will work to restore my profile from a crashed windows-7 machine to my new windows-11. Nothing listed in any forum or help desk works as described. I used to be able to just rename the folder to the exact file name on the new PC, but windows 11 won't let me do anything. It always needs admin permissions and even after I activated the admin account and assigned a password, I still cannot copy to the folder or rename the folder. Every attempt to do this on W-11 fails. It shouldn't be that hard and I'm tired of wasting days playing with this. I have important bookmarks, passwords etc. I want restored, and I need help. Nobody wants to pick up a phone anymore to assist!

I have never used "sync" because I have multiple PCs and each used for different applications and yes some go back to W-7, the operating system that actually worked well. Each PC has Firefox and a distinct bookmark file.

I went to "about:profiles" and created a new profile thinking I could copy to the new folder, but when i switched profiles I couldn't get back to the original default! HELP!

ello. My favorites have disappeared from my Windows 11 PC. It has happened once before and then I was able to get them back by deleting the sqlite file, now it doesn't work and I need your help with ending firefox processes etc.

Installed to new system because old system was updated to Win11 and it failed. Old system is only partially operable. Trying to copy (export and import html files) of the bookmarks to the new system, but even though the import seems to have worked, I cannot get the program to show the bookmarks correctly (or at all). They appear in the Manage Bookmarks window but will not appear on the desktop view. What am I doing wrong? When I import them, I select the All Bookmarks item to copy to but it copies everything to the Bookmarks Menu folder.

Hello,

My Firefox app was crashing, so I turned off my computer. When I turned it on, Firefox was completely reset: no profile, app initialization... I also cannot find my profile into my files.

Could you help me please ?

I used to have an account with everything on it

I restarted my computer and now I cant access anything from my old account. I used my same email account as before. what do I do I lost eveything

bold text'I am so fed up with these updates loosing my passwords and data, why ? All my settings are messed up and last time it took two weeks to get everything back, why? I give up total idiots for releasing updates that are sub par!

My wife's old Windows 10 HP laptop quit working last week do to some Operating System failure while it was trying to do an update. It finally did a reboot and now it is useless, at least as it is! It will NOT complete the boot process after trying all of the options offered. All that I am able to is exit out of Windows to a "DOS prompt." I am able to get to the Mozilla Firefox folder and others contain within. The new Windows 11 laptop I bought her is working fine with a fresh Firefox browser installed about a week ago. What she wants is her web links, settings and saved passwords "copied" from the old laptop and installed on the new one! We have no idea how many there are to retrieve! I'm hoping that there might only be one folder that I can copy via "command line" prompt to a USB drive and move the file(s) to the new laptop the same way. Can anyone tell me what I need to know? Thanks in advance! Tim O.

Yesterday, possibly related to updating to version 148, my profile completely disappaered. My old profiles are not visible under about:profiles, but are present on disk. They can not be imported with firefox -P. How do I get my profile data back?

Hello! Is it possible to recover older open tabs from a broken device that had sync activated? For a while they appeared in the hamburger menu in the top right, but now they suddenly disappeared, and under the "connected devices" I cannot click the device or anything. It went broken 2-3 months ago. Best wishes!

Hi there,

I woke up this morning and opened firefox. Normally it opens the days previous tabs and this morning it didn't. When I tried 'restore recent tabs' it didn't do it. When I went into history and found the previous day's back up and tried to restore it also failed. Can you help?

Best wishes, Inez

Firefox shutdown and updated automatically and now I have lost entire previous session, all tabs, and all bookmarks. I have reviewed all Firefox support to no avail. Nothing has worked.

This isn't exactly something that is broken but it is something that is plenty weird and I wondered if anyone has an idea how it happens.

I shut down my Linux laptop one day and when I started it the next day, all my tabs were gone. Annoying, but I spent some time searching for the most important ones and got on with my life.

We have a class picture book that is only accessible by faculty from campus or using the secure VPN. It helps us to learn people's names. It is an HTML file. One day, I needed to look someone up. Ordinarily that would open a new tab in the browser I have running, but it didn't. A whole new Firefox appeared for it and there were all my lost tabs.

Wut?

Now I can use the picture book to alternate between my old tabs and my new ones. How on Earth can this happen? It isn't exactly something that is broken, just something I don't understand.

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

Man hatte mir eine neue FAssung von firefox eingespielt - firefox VPN. Danach waren meine Passwörter, die Chronik und verschwunden und eine veraltete Lesezeichen-Datei noch vorhanden. Wie komme ich an meine ursprünglichen Daten? Wo liegen diese?

My bookmarks have been deleted after firefox automatical update on 15/3/2026. Does anybody know how to recover them? I have tried to import and back up but I couldn't see a solution . thanks
