Google appears to be taking over control of my firefox page. When I open Firefox, Google search and other functions appear on screen and take over. Also, most of my saved bookmarks have disappeared .This probably happened when I got tech help to deal with problems accessing my MS and Google accounts. I have always used the Google search engine but it only when I clicked on the search bar. Now it seems to have taken over and I seem only to be ableto access sites using Google Can I restore lost bookmarks so I can go direct to internet sites?

When I started my browser today, my history and bookmarks were gone. When I try to restore them from the backup file, I cannot click on any buttons in the Manage Bookmarks folder. The buttons are entirely unresponsive.

I'm no longer able to access my old computer, but I do have access to the hard drive. Is there a file that I can transfer to the new computer to sync all my previously saved passwords? I did not have a Mozilla account back then.

Hello, I have just installed Firefox version 144.0.2 on a new computer. I have access to all of the Firefox files and data on the original computer, but I am not able to run Firefox on that computer. Therefore, I am not able to create an export file from the original installation. Is it possible for me to import all of the original Firefox data into the new installation? Thank you very much in advance, Steve DeFeo

Hello, I reset my PC yesterday.

I didn't know my Firefox password anymore and clicked "Forgot password."

Then I created a new one.

Now my saved online pages and everything else are gone. So synchronization isn't working.

I have an account recovery key.

Will that work? And how?

Please help me.

Regards, Daniel

Hi, I'll try to explain exhaustively my problem and what I've tried.

While looking at adding a new profile, I made a mistake and deleted the actual profile. Firefox immediately shut, and I made the mistake to open it right after...

It started from zero, as it had no profile to go into. Creating a new profile in the same time. I did this a few time, nothing changed obviously. I went to the AppData/Roaming path to find my old profile, which wasn't there anymore. I then managed to recover my profile files thanks to Recuva and EaseUS.

But now, I'm stuck. When adding the files in the newly created profile, it seems to roll back to the profile creation prompt (like import stuff from other browsers etc.). Copy/pasting only the desired sessionstore or the previous backup doesn't work either. It also tried to put the "good profile" in the Profiles folder. Firefox didn't recognize it, and I couldn't create a new profile from this folder in the Profile Manager as it said "this name is already used" etc. (it's a default-release) I then tried to edit the profiles.ini and install.ini to force Firefox on the wanted profile. Which succeeded and failed at the same time: it opened the right profile-folder, but without any session, bookmark... and back again to the profile creation prompt. And created a new empty sessionstore, prefs, etc.

Then I'm left with my recovered backup files and no idea how to import them...

Any help will be warmly welcomed! Cheers

I rebooted my laptop with both firefox windows I had open and possibly a private window too, then rebooted again without touching firefox, and now I can only restore one of the two windows. I checked my recently closed windows in history and there was nothing there at all. Is there anything I can do at all to restore that other window or is it just gone for good now?

I have purchased a new computer and I want ot transfer al my bookmarks, login details etc onto the new one. I have followed the instructions given on your help pages, to no effect. My old computer ruins Firefox under Win 10. The new computer runs the same version under Win 11. I have copied the contents of Profiles from the old to the new, but Firefox says the profile is missing. When I copy and add the folders in Profiles to the Win 11 computer, there is no difference. The names of the folders in Profiles are different on each computer, so I think that it is looking for a particular file/folder name, but I don't know which one. Can anyone help me?

Hello,

I recently installed a new add-on in Firefox — the one that allows you to create different profiles with individual names and colors in the browser.

After the installation and a subsequent restart of my MacBook Pro, my previously open session windows were not automatically restored when starting Firefox as usual. Instead, a message appeared asking whether I wanted to “restore all session windows.” I clicked “Yes,” but none of my previous windows opened.

Since then, my saved passwords and bookmarks also seem to have disappeared. I suspect that my previous profile may have been overwritten or that a new profile was created.

Could you please let me know if and how I can restore my previous sessions, bookmarks, and passwords? Is there perhaps a way to access my data through a backup or via the sessionstore.jsonlz4 file or an older Firefox profile?

Thank you very much in advance for your assistance.

Kind regards, Diamant Adler

I need to restore my profile on this computer. my other one failed...I need my bookmarks and passwords to websites restored. I have a account recovery key. I can try to log in, but I dont know if I have my password correct

Something very bad happened to me today (11/3)....

Firefox 144.0.2 was installed on 10/30/25, and everything has been fine until today. I don't know why or how, but ALL of my OPEN tabs (of which I have many--and have it fixed so they always re-open when Firefox starts), ALL went away.

In reading conventional steps to recover such from sessionstore-backups, those instructions sounded straightforward. However, even though ALL FIREFOX PROCESSES were ended, I could not copy the contents of the sessionstore-backups folder nor could I delete anything--EVEN THOUGH I am the owner.

Even after providing Admin perms.

I could get rid of profiles.ini, which initially proved diasterous, because then Firefox thought I was brand new, so ALL of my passwords saved through Firefox these many years, went "poof".

Fortunately, I was able to get that back, but I still cannot get all of my tabs back, and conventional instructions to do so aren't working.

After recovering from my heart attack for initially losing my passwords, I am breathing a little better right now, but it sure would be nice to get all of my open tabs back again. I don't know why I am not able to manipulate the files within sessionstore-backups. I think if I could eliminate the files in that folder EXCEPT for upgrade.jsonlz4-20251027123126, which possesses a 10/29/25 date, these should be the open tabs just before the 144.0.2 installation, and all should be right with the world, once more.

I have performed/examined many steps offered under this category, but most assume I can copy them elsewhere for safe-keeping and/or removing all but the one I want Firefox to "use". Because something is preventing me from doing this, though, I am being stymied in what ought to be the solution. As a test, I was able to copy files from a much older profile--so I can prove the basic steps SHOULD HAVE worked. Unfortunately, I cannot do the same with THE (more recent) folder in question. I can't get rid of parent.lock, either (and I have ensured no Firefox processes are running via Task Manager).

Repeatedly.

Something else is at work, here. Any help or assistance from community experts would be most helpful.

Thanks very much in advance.

Hello, I reinstalled Firefox and am unable to recover my bookmarks and other data. Before the re-installation, I manually backed up my data, but when I try to restore from the backup, it does not work. All my bookmarks and previous data are still missing. How can I fix this and recover my information?

I recently downloaded some Microsoft updates. When these were completed, and after restarting my computer, my Bookmarks & History were missing. I've attached a screen shot showing the error message. I've tried multiple links to recommended steps for correcting this, but nothing has worked. Do you have any suggestions?
