Firefox Support Forum

After a crash and new Firefox update today (September 28, 2023), Firefox is now opening a new window along with every new tab. If I close the newly opened window, the tab on the browser 'main' firefox window also closes. The 'open links instead of new windows' is ticked. I have tried refreshing Firefox and also uninstalling and reinstalling. Running on Windows 10. Please help! Thanks, Robin

hello, i been runing esr releases of firefox for long time now because i really don't like many changes that get thrown in from time to time and i at least feel like my computer at home will not attack me But even esr sometimes makes me "happy" by force and now my tabs don't fit the window i am currently on firefox esr 115.3 64 bit and it must have updated from previous long support version recently because i simply can't figure out how to use it in a state as it is I kep multiple tabs open all the time, but they don't all fit on one window width and up untill yesterfday i had small scrolling buttons now the buttons are gone and tabs are all fixes size the biggest possible and simply don't fit the window , they spill into infinity on the right size and i can't even get to the tabs that got out on the right because neither scrolling by mouse or arrow buttons don't work and there is noleft/right button to press on top of the tabs

when i open a new tab,add on managers tab also opens. open another tab same thing, so if i have 4 tabs open also have 4 add on managers open it dose not do it in troublshoot mode

I use to be able to open a new Tab and automatically get the home page to appear, now it seems that I either get a generic Firefox home page or a blank one. This is not what I want nor need, if it was I would have chosen it. What is the point of having a home page if you cannot use it??? Having the home page icon now becomes a special icon for a page one just likes to use every time they open a new tab that you have to click on every time you need it. It just happens to be EVERY TIME I open a new tab.

Thanks for your help.

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

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.
