Firstly I have lost my default,. I had it set up as google . next I lost all my bookmarks, I have also lost the bar I had which included bookmarks history etc. this all happened in the middle of using a program and now I cannot get it back. PLEASE TELL ME WHAT IS HAPPENING

I'm using Firefox in Windows. I lost all of my bookmarks... never mind how, I think I can prevent it from happening again... and I'm trying to figure out whether there is a way to recover them.

Looking in the profile folder, I see three profiles. One is listed on the about:profiles page, and is identified as the default. The other two aren't listed there at all.

I need to select each of those other two and see whether my bookmarks can be recovered from them. But how. The about:profiles page has a button for creating a new profile, but not for adding an existing profile to the page. Either it's listed there or it's not.

It seems to me that I could create a new profile and make it the default folder, then quit Firefox and replace it with a copy of one of the profiles I want to investigate. However, I lost my bookmarks by doing something similar to that, so I'm wary of doing it again.

Can someone explain what is happening here--why there are three profiles in the default profile's folder but only one list listed, and why there's apparently no provision for making Firefox list the others?

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.

This is not so much as a help request as a suggestion, if someone can forward this along....

I depend on containers since they were introduced. I see now that they can vanish and are not synced nor can they be easily backed up. I have lost customer accounts now because of my dependence on containers. Had I known they could vanish, I would have continued using different profiles.

Please add a warning for those who depend on containers so that they do not end up in my predicament or remove them entirely or at least do not add them by default.

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.

After the most recent Firefox update all my bookmarks were scrambled. For example, when I open one marked Bank of America, I get Go Daddy. How do I restore my bookmarks to what they were before the update?

My FireFox was updated to version 153 and all of my bookmarks are gone. I tried to restore them in Manage Bookmarks. But when i click on 'Import and Backup', then 'Restore', then click on 'choose file' nothing happens. I navigated to the directory "bookmarkbackups" and I can see several backups, one dated 08/06/2026. But how do I get Manage Bookmarks to see that file?

I tried to bookmark a current tab and it does not show up under Bookmarks. why can't I set a new bookmark? Are these issues related?

I'm on Windows 10.

For the Troubleshooting data, I manually open about:support and clicked on 'Copy text to Clipboard'. Then pasted that into the box below.

I didn't know I need to keep a device on if I want to sync my old data. I read it thoroughly. This is annoying, I don't want to lose my Sync data from this because I didn't know. How do you guys retain your Sync data if I were to reset my password? My computer just got fixed and I don't like this greeting of where all my data like history and bookmarks flushed down because I wasn't signed-in in a device nor did I place a key or something.
