Firefox Support Forum

I Closed the browser and forgot that I had a private one open too. When I went to open the main Firefox window up, my previous session was wiped! I already tried the right clicking plus sign method to no avail. It just brings up the one I had after searching how to bring back the session and then accidentally closed the browser after. Any tips on how to get it back? Why does this happen just because you have a private window open??? Change that ASAP!

I can't turn off lazy loading. I set the following about:config settings to "false":

browser.sessionstore.restore_on_demand browser.sessionstore.restore_tabs_lazily browser.sessionstore.restore_pinned_tabs_on_demand

Nothing changes. When I start Firefox, it simply won't load all tabs. How do I fix this?

Hello I want save links to all my opened tabs in one file to move to computer later, like in desktop version I can save all opened tabs to bookmarks and export bookmarks to html. In Android version I press Share all tabs, then "Save as PDF", but nothing been done. Does it save PDF and where is it? I didn't find anything in Download and Android folders? Only thing works - copy all links to clipboard, but then I have only list of links without caption, it's hard to use

In settings it use to say "open links in new tabs" now it just says "Open links in tabs instead of new windows"... what happened to "open links in NEW tab"? That would be the preferred option. When I'm in a tab and there's a link I click on I do not want to lose what I'm currently in, I want the link to open in a NEW tab. This has really gotten annoying!

How do I get back a previous session of Firefox (windows)? Firefox froze up. I restarted my computer. Now my session in Firefox doesn't show up at all in 'History'. Isn't there a way to recover a previous session?? I've never had this issue before and had a lot of important tabs in that session that would take many hours to try and find in my complete history from all links.....

My laptop updated system just now without closing the browser. After restarting, there is no restore option for firefox. No recently closed taps and windows. But the history is correct stored. I had opened 3 windows with many tabs. I/m wondering if there is any method to restore the windows instead of click the history one by one. There are hundreds of tabs....

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

Hello,

recently i upgraded firefox to version 117.0.1. Soon after that when i close my firefox window and later than open new session, the old tabs do not reopen. This is even when i have "Open previous windows and tabs" option checked in general section of firefox setting. attached is the screenshot for the same. pls help.

Regards,

Every day I have to work and use my pinned tabs. But now, they disappear every time Firefox restarts, notwithstanding that your settings indicated Firefox will reopen all tabs on the next session. Why? Where I live there are blackouts every day, especially during the night. So I have to close all my programs, turn off my computer, and restart it early in the morning in order to work. Please turn back to reopen pinned tabs every time Firefox reopens!

bold textI get this message Gah! your tab just crashed It happens after I have already brought a site up then want to bring a 2nd or 3rd tab up

Gah. Your tab just crashed. We can help! Choose Restore This Tab to reload the page.

That is what I keep getting.

Hello.

Since some time (few months, can't really say when this started happening), the middle mouse button click on a tab stopped working as before. I will describe the expected behavior and how it (still) works on the same computer with a different browser (Chrome):

1. Hover over a tab 2. Middle-click closes a tab 3. Tabs right to the closed one move left 4. Middle-click closes a tab 5. Steps 2-4 may be repeated unless there are no tabs opened 6. Leaving the tabs bar (if any left opened) will now rearrange the remaining tabs (increase their width, etc)

Now, here is the not so great behavior I am facing in Firefox: 1. Hover over a tab 2. Middle-click closes a tab 3. Tabs right to the closed one move left 4. Middle-click rearranges the remaining tabs (increase their width, etc) 5. Middle-click closes a tab 6. Steps 2-5 may be repeated unless there are no tabs opened 7. Leaving the tabs bar (if any left opened) will now rearrange the remaining tabs (increase their width, etc), if you have left at last step 3

See, there is this extra step #4 which is really bugging me enough to actually come and ask for a support.

I am on Ubuntu 20.04, using latest version of Firefox (to date).

Many thanks!

Last October my sessions were gone after a Firefox Update. I asked for help here: https://support.mozilla.org/sv/questions/1394685 and eventually got kind help from @cor-el (that unfortunately wasn't skilled enough to understand) and from @RayGibson57. But by then, my life was in a flurry and I didn't have time to try the advice. And so, after a while I had, with some effort, gathered many of the old tabs back again, and built up new sessions.

This Monday I was trying to internet while having high fever (something people should never do :o ). I left three blank windows open when I shut down the computer, and next morning those three were the only ones Firefox wanted to remember.

(I still find this change frustrating, bordering on infuriating: what happened to "Choose how many old sessions you want Firefox to remember", I think the maximum was ten?)

Now the fevers left and I went to those answers to try. That Q/A was archived though, so I'm starting again here, from as far as I got following King Rays instructions. They were:

1. Open the application menu (3 horizontal lines) next to the address bar.
2. Click on Help -> More troubleshooting information.
3. With that page open, find Profile Folder and click on Open Folder. That's how you get to the folder with backup files in it.
4. Set computer up to see all the extensions & system files. By default, the extensions don't show up (.jsonlz4 is an extension).
5. I found an older file in that sessionstore-backups folder and copied it one level back to the main profile folder.
6. Renamed the sessionstore.jsonlz4 to sessionstore.jsonlz4.old and the file I copied, I renamed to sessionstore.jsonlz4.
7. Opened Firefox and that missing window was in the history so I could open it.
8. Don't make any typos here, because Firefox won't find the files it needs to open.

I got as far as finding the Profile folder and the sessionstore-backups folder.

But I cant find any jsonlz4 file called "sessionstore". Only a "sessionsCheckpoints" and that one is a json file, and the date modified is today.

See screenshots please!

Can anyone talk me trough this like Im a grandmother from Sweden with extremely limited coding & tech skills (which is what I am)?

This started a few hours ago and I can't get it to stop. I've tried restarting Firefox, restarting my computer, reducing the tabs I have open. It basically freezes up and then every single tab has the loading icon.

It doesn't appear to be crashing and restarting because I don't see the windows disappear at any time.

I've tried looking online but I can't find anybody else encountering this.

I have it so it normally and always have opened tabs I am using whenever I reopen Firefox. But from today, it doesn't work. I checked in settings, it is on under Startup "Open previous windows and tabs", but it doesn't do so. But if I click CTRL+SHIFT+T it reopens all my windows tabs, but in another window. It's like Firefox thinks my main Startup is that blank site, where I left of last time, and doesn't update even that on opening all tabs, it opens a completely new window instead. Very weird behaviour. Any way I can fix this? It is really frustrating.

Default browser is Firefox. When it is not already open and I click a link in email or Messages it open Google.com. It used to go directly to email link address. I am using Macbook Pro. I just downloaded Firefox 117.0 Was there a change in setup or Firefox 117.0?

I opened up my browser and all my active tabs which I have had for months are gone. I tried to go to recently closed tabs in history and it doesn't allow me to open. All are not available. Help!!

I had a FireFox installed on my Windows 10that I had several important tabs open and now after installing a Manjaro linux, I've lost my access to the Windows. It happened around 6 months ago. Now I wanna reinstall a new Windows OS but wanna save my open tabs list somewhere so that I can restore them after reinstallation. Where are they strored/saved?
