The option to restore previous session on start up does not work now. Firefox asks to close all the tabs and loads homepage on startup.

please help i am panicking so much right now i would type in all caps but i know that wont help

my session has a very very large amount of tabs and it only just started slowing down in the past 24 hours. ive never had trouble before today, but i just restarted and it only loads a completely blank page with the tab name New Tab

there is no option to restore previous session, and both restore closed tabs and restore closed windows options are empty in the library section

ive opened 2 windows and refuse to close either because im afraid it will completely remove all of my tabs forever. i will only restart in safe mode if i get a really good explanation and reason. anything that sounds risky i would really need a good explanation before i do it please

ive done verify integrity in the about:places section i think its called. ive looked around for my problem and ive submitted some recent crash report which could've been when the browser lag started

Thank you

I have the option to restore previous tabs set correctly. I have exited and reopened Firefox twice and neither time did it open my previous tabs. The second time, I opened the 3 tabs I could remember from my previous session, checked to make sure the option was set correctly, yet when I exited and opened Firefox, none of my tabs showed. And my history is empty. How can I keep this from happening in the future?

Avast wanted to removed an Addon it didn't like so I allowed it to get rid of it. But Avast Destroyed My Previous Session! How Do I Get it Back? I clicked on 'Restore All Windows' but all I got was a bunch of new windows and on only one Window of about 8 that are now lost or gone. Months to build... now if I can't restore these, it will take weeks or a month or more to build back what I had!

All open windows were accidentally closed by my young Nephew. A new window was opened, but RESTORE PREVIOUS SESSION is grayed-out.

Please help guide me. I had tons of Windows and Tabs open, and really need to restore just as they were yesterday when Firefox was last closed.

Any assistance greatly appreciated.

Hi!!

I had a lot of tabs open, but this morning my computer crashed, and when I restarted Firefox, I was asked wether to restaure session or to initiate a new one. I choose to restore my session, but instead of restauring my last session, Firefox restore my session as it was in early 2017, more or less 18 months ago.

is there anything I can do to retrieve that session?

I tried the solution of this thread, but it did'nt work (I don't find any sessionstore.jsonlz4 file in my profile) https://support.mozilla.org/en-US/questions/1234892 (I tried the last solution the best I can, but I'm not sure i did it properly, so maybe if someone is kind enough to help me getting through it, maybe it will do it.....)

Thanks a lot!!

I have been using the "restore session" feature along with a setting in Firefox to load all tabs simultaneously in the background for a while now and it has worked great. But after the latest update to Firefox about two weeks ago (now version 67.0), Firefox only loads 10 tabs of the previous session, instead of all of them like it used to. I need about 30 tabs for work, so this feature made it very convenient. Any suggestions? Thank you.

For some reason it updated without asking/notifying me about it. Then after it restarted it reset EVERYTHING. I don't see the Apps anymore, the shortcuts on toolbar are gone/back to defult items & I can't restore any of the past backedup sessions from the past week! I had at least 150+ tabs in 4 windows. And I already tried the "History> Closed tabs"restore thing. It only restores the LAST session, since I've been trying to fix/figure this out for at least 12 hours & nothing has restored the tabs from about 13 hours ago. Note: My Bookmarks & History (I've previously set to saved before the sessions I've had to restart during) are fine, it's only the many tabs that I can't restore is my sudden problem.

I am running Firefox 65.0.2 in Windows 7 Professional 32-bit. It is 8:16PM on 03/18/2019. The recovery files have timestamps:

    03/05/2019  03:09 PM         2,049,220 previous.jsonlz4
    03/14/2019  09:36 AM         2,124,762 recovery.baklz4
    03/14/2019  09:37 AM         2,124,716 recovery.jsonlz4

Why is Firefox not writing a new file when I open or close a tab? Is there anything I can do right now do get diagnostics on this problem? I believe that tomorrow I may be installing Windows patches and have to reboot, and restarting Firefox will lose all diagnostic data. Thanks.

When using the "Restore Previous session" Firefox keeps refusing to load one of the tabs I had open last at random. Then when I copy the internet address and close the tab then use the Paste and go in my address bar, it promptly crashes that tab as well. As you can understand this is extremely annoying, so what's going on here?

Session restore after crash used to work, but during my recent crashes, I get about:blank instead of about:sessionrestore.

Additionally, a problem Mozilla Firefox is having for more than a decade: Session recovery failure.

They have made it worse by adding a layer of bulk (euphemism: “lz4”), which does more bad than good. (if it ain't broken, don't “fix” it).


My question is: What exactly causes Firefox to fail recovering the session?

I know about Session Manager (only for Firefox pre-Q**nt*m) and TabSessionManager (for Q*a**um), but the latter one unfortunately is close to useless.

Reviews state: “WHY CAN'T THE OLD SESSION MANAGER BE UPDATED TO WORK ON THE NEW FIREFOX??” (user 79323d, 6 days ago via https://addons.mozilla.org/firefox/addon/tab-session-manager/reviews/) Another review: “Literally nobody asked for IndexedDB. The legacy way (storage.local API) worked perfectly fine. No need for GarbageDB!” (by user e3fa12, 19 days ago)


I am using Windows 8.1 at the moment. I have not experienced the session recovery failure on Linux so far, and it used to work fine for Windows 8.1, even with 500+ tabs. But somehow, recently, it stopped working.

I had a Windows 10 crash. When I relaunched Firefox, it updated me with old tabs. When I checked sesionstore-backups, I found that my previous.js and recovery.js date back to 2017. Nothing I do seems to lead to their being updated.

Oddly enough, the tabs restored were not from 2017 but from earlier this month, probably when I last rebooted my PC. Two files in the profile have been updated:

upgrade.jsonlz4-20200403064753 on 4/7/2020 recovery.baklz4 in real time.

So, my two questions are: 1) Going forward, can I rename recovery.bklz4 to previous.jsnolz4 and use that to restore my previous session? 2) is there any way within Firefox to manually force it to update previous.jsnolz4

Under options, I have Firefox set to restore my previous session when it reopens. Most of the time it does this just fine, but twice this summer it has lost all of my previous tabs. I read about, and found the recovery.jsonlz4 and recovery.baklz4 files, but they include only the tabs from the current session, not any of the former tabs. I often have dozens to hundreds of tabs open, and this is mightily annoying. Any ideas why this happens, how to prevent it in the future, and is there any hope of finding those lost tabs? I'm strongly considering ditching Firefox for another browser.

Hi, currently I opened many tabs in Firefox with tree style tab. Recently I found that my session not restore to the point I closed it but the specific time. (In this case, the session I close on 2020/03/12). For the tab I opened/closed after that seems not be stored. I also checked and found that the sessionstore.jsonlz4 was not updated. As my knowledge that this file should be removed when Firefox executed but it seems not. I may wish to ask if there is any solution to fix this problem while keep my current open tabs. Thanks for the help.

...until I get here. All i wanted to do was respond "I also had that problem" and say "that solution did not work for me". I try to log in. fail. look for way to register. nonexistent. If I could have simply reported a problem, I would have at least had some satisfaction. I could have just let it pass. Instead, I'm lost. hopeless Why do you do this?

What led me here? When I launch Firefox, it sometimes tries to restore a previous session. I looked up help for how to turn that off. The one article I found was not helpful.

So, please provide a link to register. So that I can respond to the questions your site directs me to. Because if they aren't helpful we users need to point out why.
