I've had Firefox since it's been around and not had this issue, I have a Mac with OS Monterey 12.6. Firefox is up to date and about two weeks ago with about 10 tabs open a tab crashed which probably hasn't happened in a couple years. I tried re-opening but it just crashed. I clicked the next and it crashed, then to the next and it crashed, etc. They all crashed soon as you clicked on them. I switched over to Chrome to see if I could even look something up because as soon as you clicked on anything with Firefox it crashed. I restarted Firefox and tabs just crashed. I let it sit and came back 8 hours later & all worked fine. A day later tabs started crashing again. On and off for the last two weeks tabs just keep crashing intermittently on Firefox and they only way to fix it is take a break and come back in an hour+. Then maybe a tab will crash and it will continue to work for a little while when you restart tab or maybe it will just crash as fast as you click Restart Tab. I currently have 2 crashed tabs and I'm surprised its letting my type this with a crashed tab, when I tried opening another, it just opened a crashed tab. I wouldn't doubt if it crashes in the middle of typing and I have to come back in an hour to finish. I can't find a solution on Google and if this keeps up, I'm going to have to drop Firefox as this happens throughout the day for work. Any Ideas what this might be? If you think it's a computer issue, I'll call Apple, but no solutions on Google make sense. Thanks for any help.

Note, these tabs are crashing on every site you can think of from Yahoo, Mail, Google, Facebook, Amazon, youtube, etc.

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)?

Hello, for my study I'm searching a lot of information on different websites for different school subjects and have currently accumulated over 1000 tabs open/active in my Firefox (web) on my laptop. I usually open websites and don't close them with the assumption and just to be on the safe side I might need them later. However, I would like to group/bundle these tabs into different categories according to the subjects I'm working to keep it manageable. Is this possible (preferably not by means of an add-on)?

I have been using Simple Tab Groups (STG) for a long time now. I am curious if putting tabs into groups saves any resources, i.e. is only the open group using resources (CUP/RAM), or is STG purely organizational in that all the tabs still use the same amount of resources as if they weren't grouped? If it is the latter, do you know of an add-on that would save resources? Thanks

Hello, I want open a private tab along side of an opened private tab . But every time it opens in an new window. So, i am shifting from chrome. In chrome when we try to open a link in private tab all the private tabs opens in the same window. So, I want to is this feature available in Firefox or not. If have how can I turn it on. Thanks.

I am currently on version 110 of firefox. It is driving me crazy how there is no physical object or deliminator between tabs. they all just blend in. Is there any way to add the "|" (pipe command) between the tabs so they have some sort of separation?

thanks

I prefer to have all my previous tabs open when I start up Firefox, which means that I don't want them to close upon exit. Recently, Firefox started closing my tabs upon exit, even though:

- I tried both hitting the X and choosing Exit from the hamburger menu
- I have checked "Open previous windows and tabs" upon startup in settings
- I have not checked "Delete Cookies and Site Settings when Firefox is closed"

- I have the option "Firefox will remember history" selected

- I do not open in Private Browsing mode

What other settings do I need to change? Debra

I've asked this question a long time ago, and received no answers. I resorted to resetting it every time, however a new problem has come about, forcing me to ask again.

Whenever I open my browser, my tabs have reset themselves to default width. I prefer them at a wider width, so I navigate to about:config and edit the browser.tabs.tabMinWidth to 100. I have to do this every time.

However, for some reason doing this now also hides/removes tab close buttons on each tab, which is problematic to my style of browsing.

I had an userCSS file, but even after removing it as a test, the problem persists. If it matters, my style of browsing has me keep two windows open at any given time. I did try to change it with only one window open, but the change did not stick.

Only tab-specific add-ons I have are FoxyTab and a tab suspender.

Any help is appreciated, be it making sure the tab close buttons do not disappear, or be it making sure the tabs remain at minimum of 100 width.

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?

Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

I recently had to reinstall firefox due to a few issues. Before the reinstall, when I opened a new tab it would open as my home page. After I reinstalled it, I was able to set up my homepage URL but there is no option for new tabs to open wth the same page. The only options for new tabs are blank page or the default firefox homepage. This was never an issue before the reinstall.

How do I fix this? Has the option been moved somewhere else?

I cannot open my familiar Firefox when I log on. The Firefox settings across the top are gone! It does not show " File,Edit,view,history,bookmarks,etc. Please help - I am lost (senior citizen, limited digital knowledge!

When I open Firefox to my home page any additional tabs that I open keep crashing. The page tells me that it has crashed and there is a restore tab button there but that doesn't work and the crash message just comes back.

Firstly, when I open a second Firefox browser window, it doesn't show any pinned tabs, and secondly, if I close the window without the pinned tabs last and then reopen Firefox, the pinned tabs are gone.

That's very annoying. Do you have a solution for this? Am I making mistakes in the settings?

Thanks for an early reply on this. Best regards Stefan

After installing the new version 106.01, restoring recently closed windows in History doesn't work even though it is highlighted as being active, but nothing shows or happens when pointing at and clicking on "Recently Closed Tabs".

(I accidently closed one of my two windows and therefore lost all my tabs.) (I know I can restore the tabs one by one, but that will be a huge task.

So what can I do to restore my lost Firefox window?

Thanks in advance. Jens Giertsen Denmark

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....
