AFTER 137.0.2 EVERY TIME I START FF ALL MY PREVIOUS TABS ARE GONE AND I BACK TO THE TOUR SCREEN. ANYONE KNOW HOW TO FIX THIS, BESIDES SWITCHING TO ANOTHER BROWSER?

Hi,

I’m writing you as a very annoyed, frustrated and seriously pissed off user.

I’m a senior lecturer at De Montfort University, Leicester, and have been using Mozilla since 2020/21 on my university account, since I don’t want Google Chrome and Microsoft Edge is user-unfriendly shit. Now, my Mozilla account was registered via DMU (technically set up by the university’s ITMS) to run as my default browser, which opened automatically logged-in and ready to go each time I started the computer. This is how it has worked for the last four years and through many, many updates… until yesterday.

Since the last update on Monday, May 19th, all my access records, settings and bookmarks have been completely wiped off. In fact, it appears that my university-registered account has been wiped in its entirety. Strangely, Mozilla Firefox is still my default browser but only opens with a standard default window. More importantly, I was no longer able to log into my account, as if my account no longer exists… which also means that all my bookmarks and links to important websites within DMU and externally have all disappeared. It will take me at least 1 week (if I focus on nothing else) to find and restore them.

So, how was such a car crash of an update actually possible? Please note that ITMS at DMU is placing the blame and responsibility of this fuckup squarely on you. Furthermore, why was this update actually necessary? Mozilla Firefox was until yesterday a far superior browser in terms of user-friendliness and style compared to Google Chrome, Microsoft Edge or Apple Safari. Now it’s little more than a cheap, equally flawed Microsoft Edge copycat both in style and user-unfriendliness!

But even worse, I now find out that Mozilla like all those "revolutionary, democratizing" tech companies cannot even be bothered to be accessible for contact when in need for support. Anyway, I would like to know how your update could wipe out my account and all the bookmarks just like that, as if they never existed in the first place. And how do I get my my original settings back?

Very disappointing.

Regards,

Markus

Hello Firefox Support,

I’m reaching out for assistance regarding a serious data loss issue I experienced.

Recently, I accidentally launched an older version of Firefox on macOS using my existing profile. After this, I noticed that all my Multi-Account Containers were still listed, but all cookies associated with those containers were completely lost. I understand this might be caused by incompatibility between Firefox versions and profile structures.

I have located files such as: - `cookies.sqlite` - `containers.json` - `sessionstore-backups/upgrade.jsonlz4-*`

However, none of the cookies appear to have `originAttributes` associated with containers anymore (only empty strings). Is there any way to recover or reassign the lost cookies to their original containers?

This incident has affected multiple work logins and multi-account configurations I heavily depend on.

Thank you for any support or tools you can provide to assist in restoring the lost data.

Best regards, Thang

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!

Today I needed to reboot my browser, and did so they same way i've done countless times before, but when I restarted it only 10 of the 11 windows I had open before closing it were in the "Recently closed windows" section of "History".Please tell me there's some way to recover that window.I had a lot of tabs open in that window that I need back.Why would Firefox just discard it like this?Like I said, i've done this so many times without an issue.

Before I get to the heart of the matter I need to clarify something. My browser have updated to the new version two days ago. When I open it yesterday it did not restore my session, I checked resently closed windows but it was clean. I looked on the forums and found out that I can use old copies of the session to restore it, unfortunately the "previous.jsonlz4" had already been overwritten, but I found three upgrade.jsonlz4 which may be suitable for restoration, I saved it and others files in another folder. It is a list of files that I have saved: 1.previous.jsonlz4 2.recovery.baklz4 3.recovery.jsonlz4 4. upgrade.jsonlz4-2025.... 5. upgrade.jsonlz4-2025.... 6. upgrade.jsonlz4-2025.... Then the forum said that I need to select one of the appropriate files, rename it to sessionstore.jsonlz4 and replace the old one. The problem is that I can't find sessionstore.jsonlz4. It was said that it appears after closing the browser, but I couldn't find it. Now after this introduction I can move on to my questions. Is it possible that this file is now called differently and this method of recovery can still be implemented? And are there other ways to restore the session? I would be very grateful for help.

In my Win 10 PC, Firefox has been set to update automatically as it is recommended.

136.0.2 (64-bit) is the most recent one that updated automatically.

Now all my extensions have been wiped out, my workspace changed.

That is such a breach of integrity, and a lack of respect for the user, and his carefully set up work environment, when an Auto-Update just molests my work environment. And then I have to take out hours from my busy routines, to devote to restoring everything to how it was.

There is no rollback feature for Updates, esp when Updates do the havoc they do.

There is no proper Session Management, and a standard protocol for saving, aggregating sessions across different installs, rollbacks, etc, and having the most updated, and complete one, where the onus is on the user not losing data.

Now I have to go hunt around for the past profiles, and name the present one as old, and hope that Firefox functions with integrity, and completeness to restore my whole work environment from the last profile. I'll of course be losing whatever work I happened to do in the new profile now. One never knows how complete these profiles are to reconstruct things exactly the way they were.

Strange. I always believe that stability, and integrity, and a dedication towards that on behalf of the user would be the primary goal. Now it's all about chasing something else, some bells and whistles, and faster performances, and throwing stability, and data integrity under the bus.

Firefox closed the browser for an automatic update two days ago, and when it came up back after the update all my open windows and tabs simply disappeared. History tab was reset to a blank page, there was no trace of anything. I tried the access through 'Menu / History / Recently closed windows' or '.../ Recently closed tabs' and they were both blank, empty, zero, nada ... This is the first time it happens to me, and I'm surprised and disappointed that such a predictable and basic bug shows up on an update.

I have a couple dozen tabs I use for task f-ups, it' unproductive and annoying to get them all back up to work. If this happens again I doubt I keep using Firefox as my preferred browser.

1. Anybody else suffering the same issue?
2. Is there a cure for the problem?

Hello, I recently had 20+ tabs open in Firefox. I moved 1 tab of the 20 to be a separate page and closed the other tabs. Now I am unable to re-open the other tabs through the 'Recently Closed Tab' feature. That feature only shows a few new tabs I opened on the separate page. Is the only option to painstakingly search through history over several months to re-open several tabs I had open for several months? Thank you the feedback, Ken

EVERY TIME I CLOSE FF WHEN I REPOPEN IT, I END UP BACK AS IF I JUST INSTALLED IT. ALL MY BOOKMARKS ARE GONE, ALL MY EXTENSIONS ARE GONE, LIKE I JUST INSTALLED IT.

I'VE TRIED UNINSTALLING AND REINSTALLING AND IT STILL DOES IT.

HELLO,

the latest browser update removed all my toolbar folders, all my Recent activity , my history etc etc, i am so damn pissed off about this as i had my work and personal websites saved in all my folders, ans all my favorite websites saved in my recent activity, so i want all them back ASAP so how do i do that?

this is urgent that someone fixes this asap , so it would be much appreciated for you to fix the issues as it was your update that done it.

thank you

Hello, Hi I recently updated (last night) and i didnt check all the boxes i clicked skip but NOW i can not recover any of the stuff from the night before is there a way u could help me ?!

I updated my Firefox browser to the latest version (133.0.3) and lost all of my bookmarks (there were so many). This has never happened to me with previous Firefox updates. How do I get these bookmarks back? I am devastated right now and really want my bookmarks back. Please help.

UPDATE: I read several previous questions and support about recovering lost bookmarks prior to posting my question. None of them applied or worked in my situation. This latest update version 133.0.3 overwrote everything in my local Mozilla folder and my old profile did not seem to exist anywhere, but after much searching I did eventually finally find the last bookmark file (after selecting to view hidden files, searched for places.sqlite in my C drive) on my computer from before the update. Next step is to import them.

Hi, I switched to a new phone recently, and wasn't able to outright sync all of my open tabs from the old device. It was, however letting me access them from the tab menu on my new device, so it wasn't a big deal.

Now I can't see the other phone in the tab menu, just the sync from my PC. I don't have the old phone anymore, because it was a trade in for my current device.

Is there any way to get my old tabs back? The sync must have timed out, because there was no activity for a period of time. I have Firefox synced on all of my devices.

Thank you.
