I thought I was updating firefox today but the process lost the order of my book marks and makes them extremely hard to find. Some I used several times a day with one click. Now it takes me five clicks just to get to them and then a search. The old system worked perfectly for my purposes. Is there anyway to get back the old bookmarks tab and my old bookmarks in relatively decent order? The text promised me all my bookmarks,etc. I never would had clicked refresh if I had any idea this would be the outcome.

My Firefox crashed when my laptop was inactive. When relaunching it didn't have my usual tabs open so I did the usual, history- restore tabs. This didn't work and only opened 2 tabs when I know I had about at least 15 open. Please tell me other ways I can do this? they are backed up in file library, how do I restore them from there? or any other way, this is frustrating.

Thanks

What happened, All my important bookmarks are missing. I have had to log into every account I have, No saved passwords. Really upset. I need help to restore all this information that I need

I'm running Windows 10 (from which I'm writing this), but I recently installed Firefox on my new Windows 11 laptop. Could this be the source of this (or other) problem(s)?

on my imac ventura 13 7 8 after a power outage my bookmarks vanished..follwed instructions to restore by going to menu,bookmarks,manage,and on library page after hitting restore nothing happens..please advise

This worked correctly before the recent Firefox update; the problem appeared immediately after updating Firefox a week of so ago.

Firefox 153.0.3 does not save session when Firefox is closed

Since the latest Firefox update, Firefox no longer restores my open tabs after closing and restarting the browser.

Firefox version: 153.0.3 (64-bit) Operating system: Windows 11

My Firefox startup setting is enabled:

Open previous windows and tabs

However, this setting no longer works.

Steps to reproduce Start Firefox normally. Open several websites in separate tabs (I tested with 3–5 tabs). Close Firefox normally using the Firefox menu / Exit. Start Firefox again. Actual result

All previously open tabs are gone.

They are also NOT available under:

History → Recently Closed Tabs

There is no usable previous session to restore.

Troubleshooting

I repeated the same test in Firefox Troubleshoot Mode, with the same result.

Therefore this does not appear to be caused by an extension.

Session files

I checked the Firefox profile's sessionstore-backups folder.

The folder contains, among others:

previous.jsonlz4 recovery.jsonlz4 recovery.baklz4 several upgrade.jsonlz4-... files

After testing with several open tabs, the current recovery.jsonlz4 and recovery.baklz4 files were only about 2.4 KB in size.

This suggests that Firefox is not correctly saving the current browsing session when it is closed.

The problem started after a recent Firefox update. Before that update, session restore worked normally.

I would appreciate it if this could be investigated as a possible Session Restore regression in Firefox 153.0.3.

So, whenever my Firefox updates, it seems that it completely wipes my history, and deletes all my tabs, despite it being set to "re-open previous tabs on launch".

This has happened multiple times now and is really not fun. Do I just need to make bookmark folders for everything I do? Because having everything randomly delete itself, without even a session restore in the backups folder of my firefox profile, isn't ideal.

I do have a sessionstore error for this, where I presume the problem is laid out.

Hello,

I keep running into an issue where my group of saved tabs disappears.

I will make several groups of tabs. When I right-click and press "save and close group," to shut down my laptop completely. There are many times when I return and try to access the saved group of tabs using the drop-down arrow at the top of the browser; all the saved groups will be gone.

Normally, I find them under "Recent Tab Groups". There have been many times when they are completely gone. Is there another way to find these groups of tabs or are they disappearing completely are a certain amount of time has passed?

Thank you,

I have recently got a new (2nd Hand) PC,after my old kit became U/S,after an attempted reinstall of windows 10. my current PC 1s windows 11. Is there any way I can Retreive my old bookmarks? I have tried getting them from my old backups,but win 11 shows them as insecure! i would appreciate some help with this problem. Is there any possible way I can retrieve my bookmarks? my old pc was a dell,my new one is HP.

I should mention that I am 81 years old and am dissabled with a long term illness, so I am not computer savvy

Thank you

Firefox prompted me to update, I hit download, my entire PC froze, I restarted the computer, when I opened firefox again and hit "restore session" it restored a session that I had opened months ago. When I checked my history, everything after that older session had been deleted. All of my history from the past few months has been deleted. I tried a few different solutions from trying to research the problem, nothing so far has worked. The only thing I have found is a session restore error saying "could not decompress file", but I could not find the file it was attempting to decompress. This is the error message I found.

Any help is greatly appreciated. I'm one of those people that tends to have way too many tabs open at once due to poor memory, and losing months of tabs and progress is a huge setback. I'm very desperate to get the history and tabs back.

I purchased a new computer and installed Firefox on it when I open Firefox for the first time it had none of my bookmarks, etc. As per the instructions on the Webb, I copied the latest profile for Firefox on my old computer and pasted that profile into the users profile folder on the new computer. For some unknown reason, Firefox is not installing this profile. The profile is approximately 330 MB. So I’m assuming there is a lot of data that is stored in that profile folder. Can you please direct me as to how I can use the current Firefox profile that I have from 8-4-26. Thank you

You did updates this morning which annoys me anyway. You do updates too often and at the wrong time of day. After you did updates, everything, all my bookmarks, etc. are gone. It's a blank screen.

I lost all bookmarks after running a Firefox update near the end of June. I have not been able to recover them. I believe I deleted my original profile inadvertently so not sure if there is anything I can do to recover them. Suggestions?

I made a change somewhere that caused a total loss of history/open tabs even in my tab manager extension. I can't remember exactly what it was I changed but nothing I have searched here has been helpful in recovering from this. I did not want to bring my profile from home as I am using Firefox here in a work environment. Can someone point me to or explain a step by step method to be able to do this? Nothing I found in searching here has been positive.

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!
