Firefox Support Forum

The tabs I had open were important to me and I went on a deep dive into the history of China and I'd like to reopen all of those tabs even if they are to be made public as I don't know if I can remember to reopen all of them.

Is there a way to find the tabs I had opened???

Any help would be appreciated!

Hi. sometimes I attempt to open a bunch of tabs and visit them later while I'm offline. the problem is when I open these tabs, All images hasn't been loaded and seem to be waiting for the internet connection to load. I've tested it on other browsers and none are like this and its really annoying me! Please help...!

It's so frustrating that the keyboard shortcut for closing tabs is right beside the one to quit Firefox. I've lost countless hours because of this, and it's so easy to accidentally do. Is there a way to keep this from happening? A simple "Are you sure" confirmation dialog would be great, or I really like the Chrome "hold command-Q" to exit feature. This seemingly simple function is proving extremely difficult to accomplish.

Yes, I'm aware of session restore, but (1) It does not preserve my window arrangement. I use multiple desktops for various tasks, and they each have related browser windows. (2) I need to see webpages exactly as they were when I opened them. Sessions expire, dynamic pages are refreshed, content is removed etc. That is all lost.

I do not want to disable session restore completely. It can still be useful. But, I do not want to trigger session restore automatically every time. Manual activation is ideal.

regarding: "browser.tabs.warnOnClose" I do not want a warning for closing multiple tabs. I often have many windows open and that warning gets annoying. It also doesn't prevent me from accidentally quitting when I only have one tab open.

I tried setting browser.warnOnQuit to true, but it's ignored.

I simply want a confirmation when I use the keyboard shortcut to QUIT. That's it. No side effects. Can Firefox do this?

I searched this forum but couldn't find an answer. I have "restore last session" turned on, but I'd like Firefox wouldn't reopen my last visited site after I close the browser by closing the last tab. In other words: if I close the browser by a regular means (by clicking the rightmost upper X, or by right-clicking the taskbar and choosing close window) it goes to the last viewed site when I reopen the browser – and that's ok – but when I close the last tab and the browser closes, I don't want to see this site again when I reopen Firefox. Is there a way to achieve this? By the way, this is the standard behavior in Google Chrome.

I use Send Tab to Device all the time. To my phone, my tablet, my work & home laptops. Except recently, the tab I send won't show up on my phone. Notifications are enabled. I can send from my phone to my work laptop. I can send from my work to home laptop. But to the phone, it says sent, and nothing ever arrives. Everything is synced. What else can I do?

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

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!!!!

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!

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!

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. George

Hi there

since a few weeks it happens daily that by accident I transfer a tab into a new firefox window obviously by moving/clicking the mouse quickly in a way that leads to this new window. then I need to copy the email adress, close the new window and make in the original window again a new tab and paste it there and place it on the right spot. not really handy... not sure what changed in firefox since this did not happen in the past. did there change sth or how better said how can I avoid that this is happening, can I lock tabs that they will not get a new window. does someone know this problem? Thanks Andy

what does a separate tab titled "about:policies#documentation" mean please? It suddenly started showing up as a 2nd tab whenever I open Firefox (Win10) link: about:policies#documentation

Okay, so I have the option set in Preferences -> General for "Restore previous session".

However, when I restart the browser, all my open tabs are lost EXCEPT for any pinned tabs.

Does anybody know why this would be?
