items dragged to overflow menu pop back out, will not stay there - dunno how to fix this.

Hate the "puzzle piece." Involuntarily upgraded to 115.25.0esr and it lost all my bookmarks, addons, history. How do I know which profile was the most recent, before the update added a new profile? How do I find my addons from the previous version? history?

Hi! i was wondering why my firefox reseted after reboot. i have all the important tabs and bookmarks for my university work, chores and articles, platforms that are mandetory on my uni. also, i was tinkering with partitions before the reboot because my steam didnt want to run any games. i was guided by the chat gpt with terminal coding to do get steam working even tho i didnt solve the problem. is there any way you can help me?

Hi, my session with a lot of open tabs has been lost due to a crash. In the profile folder, the recovery and previous files in the sessionstore-backups have been deleted. I tried to recover them using shadow explorer, but these files are corrupted, so I've had no success reading them. Is there a way to fix the corrupted files? Alternatively, because I've had sync enabled for open tabs, is there a log for past open tab synchronizations? If this was stored on the cloud, it may be possible to retrieve that table and restore the list of open tabs that way?

I have a profile that causes odd behavior, within the profile, and to the OS.

Regarding the profile itself:

1. I use Multiple Tab Handler, which should allow me to move tabs on the tab bar with the mouse, but it does not (see image of proper behavior)

2. Normally, i can drag this padlock button to the desktop to create a shortcut. but now, it will not move/drag (see image 2)

3. I also have a backup profile from several months ago that has none of the above symptoms. However, If I substitute it's sessionstore.jsonlz4 file with the the one from the problematic profile, all the bad behavior mentioned above re-emerges.

I know this sounds strange, but, I also get external display issues when using the broken profile. These events are random, and manifest themselves differently, so I can't duplicate them. Essentially, these snips are examples of images from the taskbar tabs, or the clock area, suddenly superimposing themselves on the top portions of the taskbar toolbar area.

This is the view of my clock area (see next image 3)

In the following image, imagine that the portion on the left, that opens the start menu, is now hidden under what looks exactly like the clock area on the right, superimposed over it (see next image 4)

Those aberrations are removed by simply moving the mouse cursor over them, but they will continue to occur in any number of variations over any area of that top toolbar.

Is there a Session Manager that will save the session, to be later restored into that previous profile, but not also pass along the corruption?

I have years of bookmarks that have disappeared and my history is missing. Firefox opens with the tabs that were open when it shut down. I really want my bookmarks back.

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 ?!

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

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?

After updating to version 138.0.1 for PC today I lost many bookmarks from my saved bookmarks, and also cannot restore the last saved bookmarks folder through the Firefox "Manage bookmarks" menu. HELP!

I have tried every support advice I can find and no matter what I do passwords are not restoring. Here is what I have done: Opened about:profiles Opened profile folder Exit firefox transfer key4.db and signons.jstor files from backup to the new folder

Nothing happens.

I have tried creating new folders and following those steps. I have tried everything.

My Win10 & Win11 pc's updated to this version and they all have the same problem: The bookmarks have disappeared. Including my pinned bookmarks on FF's opening page.

I also just noticed that there are no "toolbar items".

Help, My computer performed an automatic update, rebooting itself and all the history on Firefox has been lost all my open tabs have disappear. I followed other instructions to open the Profile Folder, but the only 2 files there are the ones created after the reboot. There are no previous files. Thanks, Juan

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!

My laptop unexpectedly closed Firefox after it crashed and upon a restart I re-opened Firefox, which normally restores all my open windows/tabs from the very last session no problem whenever it force quits due to laptop crashes. But this time when opening, it restored windows/tabs from almost a month ago. I closed Firefox and checked the sessionstore-backups folder: - the recovery-backup files are from the session date I just re-opened with old tabs - the previous.jsonlz4 file is from about a month ago and seems to be the reference point used when restoring tabs rather than my actual last session

Is there any other file or method I could use to recover my actual prior session tabs before it crashed?

I have not re-opened Firefox since quitting the browser after seeing it restored the old tabs.

Thank you in advance!

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

Dear Mozilla Geeks—

As practically every other Firefox user, my bookmarks evolved into a lengthy file system that uses folders to segregate categories of bookmarks.

That is, it used to have this feature.

After the last update all or most of the bookmarks (I can't tell by scrolling down the long list) are devoid of their organizing folders. This puts a great deal of information beyond easy reach. In Mozilla Help topics one is advised to click on the library icon in the toolbar ... only there is no such icon on my copy of Developer's Edition.

Can someone suggest a method or methods to recover the folders?

Some passwords have been lost as well.

Yours Sincerely,

Glen

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.

I asked a question about a week ago. I can't even see the question anymore. While this was going on I received these emails. All times are in Australian CST.

I am as much a believer in security as the next person but I don't understand what is going on,

I have had no response to my original ticket, which I beleive was number 305857 which I can no longer find any refernce to in my account, and I still have a completely blank Library! and I can't even make any new bookmarks!

Plaes help, Yours sincerely, Ms Jacq Felis (AKA Kaelkitty).
