Firefox Community Forum

So I had a laptop that had to go under repair (device A), so had to use a different computer (device B). I sign into Firefox, and I can see the synced tabs from device A. For various reasons, the very next day I had to transfer to another computer (device C), so I logout of device B, and login into Firefox in device C. The synced tabs are no longer visible, even though in my account it says device A is still connected to the sync.

Bookmarks and such still load up just fine, I just can't see the device A synced tabs at all. Any clue why this is happening?

Also, is it normal that my email is still showing on the device B menu? Even though it says I logged out successfully, and device B is not showing in sync anymore, in the actual computer it's still showing on the menu above the "new tab" option. How do I remove my email from showing in that particular browse? Uninstall the program entirely?

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!!

Whenever I open a link in a new tab from a pinned tab (using ctl-click "open in new tab" or cmd+clicking) it switches to that tab, even with "switch to new tab immediately" disabled. I would like it to just open the new tab and not switch to it, but I can't find any option in the settings or about:config that would change it. Is there any way to do this?

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)?

I have custom URL's set when opening my homepage. For the last few weeks, Firefox has been opening tabs from the last session. I've checked the URL's and they are correct in the settings but for some reason they're not loading properly.

These are the correct URL's in the setting page. https://www.etsy.com/your/shops/UiJewelryMaui/tools/listings/state:sold_out,sort:sold_out_date,stats:true|https://www.etsy.com/messages?ref=seller-platform-mcnav|https://www.shopify.com/|https://maui.clareityiam.net/idp/login|https://outlook.office.com/mail/|https://calendar.google.com/calendar/u/0/r?pli=1|https://www.microsoft365.com/?auth=2|https://www.canva.com/|https://hawaii.infinitecampus.org/campus/portal/parents/hawaii.jsp|https://mauinews.org/pub920.htm|https://www.mauicounty.gov/Bids.aspx?CatID=19|https://hiepro.ehawaii.gov/vendor-dashboard.html|https://us2.admin.mailchimp.com/campaigns?ref=plums_nav&_ga=2.43380451.756894218.1698551103-1299448220.1698551096#f_bucket:recent;t:campaigns-list|https://hawaiicovid19.com/

However, the pages that load at start up are not these URL's, instead they're opening with the ones in the photo I provided. How do I fix this or do I need to select a different default browser?

Firefox unexpectedly closed on me and when I opened it up again it did not immediately give me the option to restore closed tabs. So I went to the menu to click on restore closed tabs there but the option was not provided to click on. How do I restore tabs under this scenario? Thanks.

Is there a shortcut to deattach tabs from one browser window so it turns into seperate window, so that you don't need to deattach tabs with clicking and dragging them with mouse?

Past experience. With just a few tabs open there was a "+" button at the right hand end of the tab bar for a new tab. When the number of tabs got too many (in my case 18) the "+" button was JOINED by a ">" button to be able to see tabs off the right hand end of the toolbar, but still use the new tab button.

Post update to the current version of Firefox, at the point the ">" button appears it is REPLACING the "+" button.

I know there are workarounds, but my "rut" is to use the "+" to get a new tab.

Is there any way of getting it back?

Prior to recent updates, Firefox tabs that were opened from a link on a webpage would always open right next to the current tab. Which was fine and wonderful. Sadly, following recent version updates new tabs opened from links now tend to 'wonder' off to the far end of whatever other links may have also been opened previously from that site. The problem with this new behaviour is that such tabs quickly become lost amongst the various branches of the tree as other links are opened in 'child' tabs of links that have gone before. In short, this new behaviour results in a complete confusing mess, especially as the newly opened tabs may end up so far off to the right that it's difficult to find the way back to the page they were opened from! Please could you at least provide an option so the user can set new links to open right next to the current tab, as they used to do, rather than some no doubt logical but nonetheless baffling and impractical location some 6, 21 or even more tabs away from the current tab. Thanks

I had 2 windows open, closed one, lost all of my tabs. Restore didn't work. I tried to restore by renaming session-store-backups folder files. doesn't work. There is a file called upgrade.jsonlz4 from November, maybe that could be used to restore tabs somehow?

About 3 weeks ago I started getting these message windows 'Gah. Your tab has crashed.' I have never seen these before now they're everywhere. I have tried all the Troubleshoot procedures and nothing seems to help. I've done all the cleanups and checked the add-ons but there is nothing new and no changes I am aware of.

I have the add-on Tab Stats. This lists and groups tabs by unique domain or unique URL listing duplicates in a separate sub-tree. On each url item there is listed the last access date/time.

Is it possible to get a list and group tabs by last accessed date? I've put in a request on the extension for this feature - New tree - List by age exponentially but the authors appear inactive and unresponsive.

What is the best way to encourage development of this feature if not available in pre-existing extension or feature (which is preferred of course)?

All my important tabs = gone. Nothing under recently closed windows. Most of them too old to be found in recent history. I'm mortified. I normally love Firefox updates but now I want to yell at someone :(
