Subject: Urgent Complaint: Complete loss of passwords following browser update – Priority: High

Dear Support Team,

I am writing to you today to file an urgent complaint and to request immediate technical assistance.

Following today's update of your browser, I discovered that all passwords stored in my account have been deleted. As I strictly depend on this account and the stored credentials for my daily work, this loss of data constitutes a significant disruption.

My previous attempts to recover the data via standard recovery functions have unfortunately been unsuccessful.

I therefore request your immediate assistance in restoring my data. Ideally, a rollback of my profile to a backup state from this morning, February 25, 2026, at approximately 08:30 AM, is required to restore the state prior to the faulty update.

Please inform me immediately of the steps you are taking to resolve this issue. Due to the urgency of this matter, I look forward to your response within the next few hours.

Sincerely,

Hello, I have been having some problems with my computer and ended up with 2 Firefox versions. They are both exactly the same 115.33Oesr. In the trouble shooting information it looks like they are exactly the same. The main difference is that the older version has all my Saved Password Logins. The newer version does not.

Another interesting thing is that only the newer version is in my Programs an Features. It says it was downloaded today. I downloaded a few days ago. I did do a System Restore to take care of another problem.

I was hoping to uninstall one of them but only the newer version is the one showing in my Programs. I am afraid to uninstall it and end up not having a Firefox at all or to loose all of my Saved Password Logins from the older version that is not showing in my Programs. I have a lot and I use them constantly. Just easy to sign in. Too many different passwords, impossible to remember. I do have a book with all of them but it takes forever to find them. How can I merge all these Saved Passwords Logins to the newer version?

I would really appreciate all the help I can get, please!!!!

Amy

I have used the OneTab browser extension for years. Mac computer ran out of space but was completely backed up. Got new computer. copied Firefox profile from the and updated the profiles.ini to use the backup data.

I used a backup dated 12 Feb 2026.

I was able to restore my bookmarks and passwords from this profile, but they seem to be from many years ago. I was not syncing to my Firefox account and saving the passwords to my computer. i assumed they would be in a bakup. None of my OneTab items were restored.

I wonder if part of the problem is that Firefox wants to ( and did) update my new computer to Firefox 145 or 147. I don't know which Firefox was running when I had the issue but I suspect it was older.

All of the storage/moz-extension files are there and firefox is using the correct profile data. Is there any way to find/read/extract the OneTab history? Where should I look? I contacted OneTab and all they could tell me was to look in storage/default/moz-extension.. ( nothing readable there) Thanks

Hello,

This morning Firefox stopped loading new tabs, which usually means it is due for an update and restart. On my work computer, updates are managed by my organization, so I cannot prompt it to check for updates directly, but rather can just restart the application and it updates once closed. Today when I closed the window then clicked the shortcut to reopen, it notified me the exe file had been removed and prompted me to open the Windows store and reinstall, which I did. I have no indication as to why it uninstalled. All of my bookmarks and other history appear to have been wiped.

I have been trying on the support site to see if this data is recoverable, but nothing has panned out so far.

I have used Firefox as my primary browser for almost twenty years and frequently encourage friends and family to use it if they don't already. I have never experienced anything like this before. I am hopeful somebody will be able to assist me where reading through support center options hasn't yet, but if this is not resolvable, I'm done- the crash helpfully wiped everything clean, after all.

Any suggestions or response is greatly appreciated. Best, Z

Cannot get in to my daily bookmarks .They ask now to sign in as new member. I cant check my bank accounts or medical sites or any bookmarks info at all. all went away. Please help !!!!

Firefox updated itself, and re-opened without all my tabs from the previous session. That session isn't available in history. Is there any way I can get these back? All my work was organised in tabs.

Note there are no enterprise policies in place.

When Firefox updated I only created a default profile and could not or did not import bookmarks. They seem lost now. I was offered to import from other browsers like Edge but did not see any way to import from my previous Firefox version. I am unable to find any automatic backups in bookmarkbackups folder.

”Using my HP Notebook computer, BOOKMARKS (in Mozilla/Firefox): Who governs my access to my list, which disappeared on 2/20/2026. It looks like Google (i.e., Yahoo) has taken control of this function……….and, if I set up Sync on my computer, how will my current DEFAULT YAHOO EMAIL be impacted?”
