Can't restore TABS from backup file

Before shutting down Firefox I deleted history/cache/passwords etc from the past day

I do this all the time but since I had restore previous tabs selected they always get restored when I start up again

However this time they weren't restored when I restarted

Without closing Firefox I navigated to the sessionstore-backups folder to see what was there but the files were only 2KB - much too small for the number of tabs.

So I installed ShadowExplorer & Shadowcopyview to see if I could recover older versions I was able to locate jsonlz4 files from a few days ago that were around 11000KB in size so I assumed they would have most of my tabs

However when trying to use the files nothing happens - I tried 2 different steps that I read here had worked for others

1 - Renaming previous.jsonlz4 to sessionstore.jsonlz4 , moving to the profile folder (deleting the old one first) and restarting FF

2 - Deleting sessionstore.jsonlz4 and copying the recovered previous.jsonlz4 / recovery.baklz4 /recovery.jsonlz4 / upgrade.jsonlz4-20201014125134 files to the sessionstore-backups folder and restarting FF

I also repeated the steps after creating a separate profile

None of these worked so I tried examining the jsonlz4 files using https://www.jeffersonscher.com/res/scrounger.html but I got an error message 'Session history file contents could not be read?'

Now I've previously used recovered Jsonlz4 files to restore tabs with no issues but this time they won't work

I read here https://support.mozilla.org/bm/questions/1189759 that updates may cause compatibility issues and the upgrade.jsonlz4-20201014125134 file indicates they was a recent update

The recovered file sizes indicate they contain data so I want to know how I can recover it - if not through FF then through some other software

firefox tab name edit: can a user name tab at will ?

right now it has LOGO and "Home" but i want it to read something like OSC-US Office of Special Counsel-Independent Agency-Home because i just do.

i have three other bookmarks for OSC: i can edit the bookmark name from "properties" but have never known whether i can also edit the name shown on a tab.

LOGO Home isn't too helpful to me. but even just knowing that i CAN'T edit tab names will be helpful to know, so i can stop thinking about it and get some sleep after another bag of chocolate-chip cookies. being an american right now is plenty stressful.

who named them "cookies" anyhow?-is it bc they kind of leave crumbs? did i win?

thank you for helping. i do appreciate it.

All Pinned And Open Tabs Lost ☹

I got an error on one of my open or pinned tabs (do not recall which it was). I do not recall what the error was and did not screenshot it because I was sure that closing Firefox and restarting it would fix the issue. I did just that, closed Firefox and reopened it to find that ALL of my pinned and open tabs were GONE. This also happens if another instance of Firefox is opened and I close my main one first by accident and then close the other Firefox instance - ALL TABS LOST.

This is what I have done: • I started to restore the pinned tabs as I could remember what they were but I was not able to remember the open tabs that were not pinned • I searched for lost tabs on the web and on the Mozilla support site but was not able to find any useful help - most of it seems outdated or no long compatible with my version of Firefox. • I looked for the sessionrestore files on my local PC but could not find them - this must have changed in some version of Firefox between version 42 and version 82 that I have. • I looked in the AddOn store to find something that would help restore and prevent this issue - but found nothing. A very old post, from 2012, indicated one that did this but it is no longer available. • All of the Options in Firefox to restore previous session, reopen previous tabs and all that were blank.

This is VERY frustrating in that it results in lots of down time to recreate what was open and is equivalent to working on a document for days or weeks only to find out that the Microsoft file got corrupt or did not save properly.

I am using Firefox version 82.0.2 (64-bit).

Two questions: 1/ Is there any way I can get the pinned and open tabs back from the previous session? 2/ What can I do to avoid this issue EVER happening again.

Thanks!!!!

Can't seem to recover my session

Hi,

I always have dozens of tabs opened, if not hundreds. They have vanished. I’ve been trying to follow the topics on the matter, such as the one named ‘Session won't load’ (questions/1254740), to no avail.

Finally, this time I remembered not to close Firefox when I saw my tabs where suddenly missing. I’ve never seen the ‘Restore the previous session’ on the Firefox menu, and neither did I this time. Without closing the browser, I did a backup of the ‘sessionstore-backups’ folder. It contains:

‘previous.jsonlz4’, from 22/11/2020 17:42 ‘recovery.baklz4’, from 22/11/2020 18:57 ‘recovery.jsonlz4’ from 22/11/2020 18:58 ‘upgrade.jsonlz4-20201027185343’ from 31/10/2020 13:42 ‘upgrade.jsonlz4-20201108180448’ from 10/11/2020 15:05 ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34

The one I need is ‘previous.jsonlz4’, since by 18:57 I’ve already lost my tabs. From the update backups I think I could also use the one from 22/11. In any case, I don’t understand what I am doing wrong so as to recover the ‘previous.jsonlz4’. This is what I’ve tried from different threads on my profile folder:

The ‘-backup’ and ‘OLD’ changes belong to different attempts

- Rename (on ‘sessionstore-backups’ folder) ‘recovery.jsonlz4’ and ‘recovery.baklz4’ to ‘recovery-backup.jsonlz4’ and ‘recovery-backup.baklz4’, and also tried with ‘recoveryOLD.jsonlz4’ and ‘recoveryOLD.baklz4’ - Rename ‘sessionstore-backups’ folder to ‘sessionstore-backupsOLD’ - Rename (on the main profile folder) ‘sessionstore.jsonlz4’ file to‘sessionstore-backup.jsonlz4’, and also tried with ‘sessionstoreOLD.jsonlz4’ - Copy/paste the ‘previous.jsonlz4’ file into the main profile folder. - Rename ‘previous.jsonlz4’ to ‘sessionstore.jsonlz4’

Nothing has worked. Once followed the steps, Firefox keeps opening my startup page. Note that it does not restore my previous session (that is, some tabs regarding this same subject), but my startup page, which means my attempts are having some effect, although not the desired one. I do have the ‘Restore previous session’ checkmarked in ‘Setting/General/Startup.

I also tried to replace ‘recovery.baklz4’ (on ‘sessionstore-backups’ folder) with ‘previous.jsonlz4’, from 22/11/2020 17:42, hoping to be prompted with the ‘Well, this is embarrassing’ + ’Restore’ window. I had no success.

I’ve been trying to recover my tabs for hour by now and don’t find what I am doing wrong. Why does Firefox refuse to load my ‘previous.jsonlz4’ file? Am I missing something? Maybe ‘previous.jsonlz4’ is corrupted or something? Should I try to use the ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34 file? (Although I would lose some information)

Some people talk about a ‘History > Restore Previous Session’. I cannot find anything similar.

Thank you very much

I think it was update, my pc restarted. But it usually asks weird. I lost all windows and all tabs. Yet in library/history under restore windows, there is nothing! There was some json file, from which you could get tabs. I tried it last time and it didn't work. Also firefox wasn't even running at that time and previously i had all windows and tabs... Are you kidding me???

I lost like hundreds of important tabs.... Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa............

Hi. I would like to restore my previous session when I open Firefox (last version of the browser installed). The option is turned on, but nothing happens when I close the browser and I open it again. The support says I should see "Restore previous session" after "New Private Window", but this option is not there. In the history, the list of recently closed tabs is always empty, there are juste one or two links in the recently closed windows (it seems to be a random list). Can someone help me ? I don't understand why it doesn't work. Thank you :)

When i switch on my computer i have to make sure that i open Firefox and restore the previous session before i do anything else.

For example, if you click on a link in an email - and if Firefox is not open - then it will open Firefox and you have lost access to your previous session tabs.

Yesterday, when i switched on the computer Adobe wanted to remove a program - so i uninstalled the program and then it opened a page in Firefox so i lost 50 tabs. Sigh.

SUGGESTION As well as having the option to restore the previous session could we please have the option to restore the session before that? I think this will make a lot of people very happy.

Hey!

First time I get that, I usually lose my tabs due to my mistake but this morning after starting my PC all the tabs were gone with no option to restore or any error message. I backed up my previous session json and other files by hand but every time i copy it back into my profile folder and rename it sessionstore.jsonlz4 it just gets deleted after I open firefox and none of my old tabs get loaded. I scrounged the files before and saw that they contain my lost tabs, I just can't seem to restore them. I tried reinstalling firefox too but that didn't help.

Did the restore system change or is the backup corrupt ? Thanks!

Fred

When firefox is in full screen mode, as soon as I take my mouse cursor to switch tabs the Mac Os action bar (bar with close and minimize icons on it ) covers the tabs and make it hard to switch tabs, same happens while reaching for address bar which extremely annoying and frustrating.

I see other applications handles it really well for this situation so its not the macos issue. I reported this on twitter too but no satisfying response. I like firefox and don't want to switch back to other browser so please fix this. This issue is extremely frustrating and impacts the core functionality of the firefox or browser in general.


I have attached images from Chrome and source tree, both are third party application. Best handling of this action is done by safari, which smoothly animate and make the space for close and minimize buttons along with the tabs but that's a first party app and not sure if the same can be achieved by third party apps.

I am running Big Sur but this was happening even in Catalina.

Thank you!

Hi,

I just downloaded Firefox on my new PC (laptop) but for an unknown reason opening a link in a new tab doesn't work. Opening a link in a new window doesn't work either, and opening the link in a new private window does not work either. It is getting frustrating to say the least, as I've never encountered this problem before and I have no idea what to do. :)

Thank you kindly in advance for your help!

When I open a link in a New Tab, Firefox continually returns a blank page. (Previously, Firefox would happily open up to 10 or more Tabs for reading later, without batting an eyelid)

Firefox even declined to open my Home Page a short while ago.

The only extension I am using is Adblock Plus, and even disabling it, or restarting in Safe Mode, makes no difference.

I am using Firefox release 83.0 - and I've tried turning off Hardware Acceleration - again, no difference.

Any help/advice much appreciated Robin

For last few weeks whenever I open a new web browser in firefox the screen display now open slightly off screen with the top having moved up (and also a little to the right) making the scroll bar barely visible and tabs not visible. I can grab and move sometimes but it has become a consistent problem and I do not know why. Nothing has changed that I am aware of. How can this issue be fixed? Thank you

I HAVE SYSTEM RESTORE ON MY FIREFOX. When I purposely restarted my computer, for an unknown reason, a session came up but my previous session did not automatically restore as usually it does. I did something in that window and was thinking about something else and deleted it, ie: the session. OH S _ _ _! Just lost my restore previous session opportunity..... I opened another session (and restore previous session was grayed - not available) and have not closed my session nor re-started since. Is there any other way to go back and recover my lost session windows and tabs? .... not from the previous session that I accidentally closed, but from the session before that? Thanks in advance.
