Firefox Community Forum

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

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.

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

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 had many work tabs open when I left the office yesterday. The update that occurred overnight closed and erased my current window, and now the "restore previous session" option is not available. These were collected over months, so the general 'history' page is not helpful in this instance. How can I restore my previous session and get all my open tabs back that I had yesterday?

Why did you remove my Google Email and passwords? Fire fox lost my passwords Google email and other stuff. I may have 1000 or more emails that I can not read!!!!!!!

I opened firefox this morning on my laptop and it froze and shut down. When I opened firefox again it opened as a new window and all of my tabs and tab groups were gone. They do not show up in my history or recently closed tabs. Previous session is shown as current session so no option to restore.

Is there any other way to get these back?

About one to 3 weeks after I switched from windows, Fire fox changed my browser, and I lost all of my data. I hate my new browser, I am so mad That I reported this to the FCC. I already view all Info. nothing helped.

So I just upgraded my pc and it bricked my windows and to reinstall, I forgot to save the Firefox data before doing so because I thought it wouldn't cause any issue, well, now all my bookmarks etc. are gone and I'm wondering if there is some sort of backup somewhere saved by Mozilla in the cloud.
