Firefox Community Forum

Recently, Firefox updated and ask me to setup a profile, which I have not yet done since importing my data from google chrome in 2025. After skipping the setup, Firefox then deleted all my data and it has since been irecoverable. I have already checked the box last update that specifically said to not ask me again for setting up my profile. After the recent update, the question popped up again and now I cannot recover my original profile, all my browsing history, all my browser-saved data, and all my cookies and logins

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

I had a ton of saved tabs and groupings of tabs. I closed what I thought was my only open Firefox window then downloaded and installed the most recent Windows update. When I rebooted, I did not realize I had left a Firefox window open with a single tab. That Firefox became my default and I lost all the tabs I had. Is there any way to get those tabs back? The tabs I had yesterday, 1/22/2026 are the ones I need.

I opened my computer several days ago. Firefox updated itself sometime recently while my laptop was closed. Once I opened it, it made me create a profile to continue. Now ALL of my history is deleted. All of my windows and tabs are gone. There is no history beyond the profile it made me create to continue using it. Is there any way to get back the previous history? This is about enough to make me give up on firefox completely.

My bookmarks suddenly disappeared. I tried to use the troubleshooting guide for "My Bookmarks have Disappeared" bold textbut when I click on <Manage Bookmarks> step nothing happens. Also, when I click on the star to make a bookmark, nothing happens.

yesterday i had all my stuff like every other day, and for some reason i randomly got logged out of alot of my accounts. Now i woke up this morning and the entire browser was reset. no bookmark shortcuts, no tab collections, all account locked out for no reason, what's going on?

I don't have any backup for this, and i didn't think i'd need it, because i'd never delete all ym data for no reason.

Is there even a way to get it back?

My bookmarks disappeared and I do not know why.

I have tried to restore bookmarks following the directives obtained online. Somehow this has not been successful, and this remains a giant puzzle to me.

I can see the bookmarks in Library, but I have not been successful in figuring how to transfer that listing to the Bookmarks tab at the left-sided top of the frame of the browser.

Thank you.

lost all bookmarks and can not add them back. tried the restarting, importing from Google, etc. Sadly I am off of Firefox after more than 20 years using it. Fortunately Google works fine for me, but I miss Firfox.

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,

I was using my web browser and I tried to load a pdf on word. The Mozilla asked me to sign in and all my bookmarks and history was gone. A VPN was up in the tip right hand corner appeared that I had never seen before. I have no idea how my original homepage disappeared and all my bookmarks with it.

I retired an older desktop unit several months ago and am no longer able to access the bookmarks associated with my account. My profile information now says account disconnected, followed by my email address. Below that the words Profile 1 appear. The menu below is the regular menu for actions on Firefox but none of the bookmarks from the original computer appear. Is there some way to access them?

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.
