Running FF V140 on Windows 11, "naming" a window has disappeared & no "Restore Previous Session" in menu

In early June 2025 I finally ditched Windows 10 for 11 and I've been a Firefox user since practically the very beginning of Mozilla.

Now, I notice that the "Restore Previous Session" button in the drop-down of the FF menu is missing. Additionally, I discovered late in the game that Mozilla DID listen to me and gave us the ability to "name" or "tag" an entire window in the browser. This was a HUGE boon to productivity as I'm constantly toggling from window to window to tab to tab.... Now, with the most recent update this ability seems to have disappeared....

The ultimate message about the damn X button to close tabs, for Firefox's UX Desdainers, and for our hero Cor-El.

Hi.

This message has three sections: little background, little rant, and little help from my friends.


Little background: I use PCs since Commodore 64, and internet since dial-up modems. Apart for some curiosity attempts with other browsers, I always used Firefox. Back then you either could do some DIY or you were done for. So, I am not a noob. And yet I am not a programmer, and do not have to damn be in order to use a damn internet browser. I have no words to express how negatively the choice of changing the behavior of the X button, to make it disappear when a certain amount of tabs are open, affects my user experience with Firefox. I tolerated it version after version. Found mentions of about:config tweaks which never worked. Found mentions to css codes which seemed so complicated that I just gave up (I also don't have much capacity for such things atm). I was ready to get rid of Firefox today after all this time of being loyal. I would have, if it was not for Cor-El. (Cor-El you can put this testimonial on your website if you'll ever start a consulting business).


Little rant: I SO SO SO SO SO SO MUCH HATE bad UX Design! And the FIRST definition of bad UX Design is when a designer imposes their own tastes and preferences on the users, or makes assumptions (based on their own usage) about how users would do things. I don't give the lesser s... if Firefox's UX Designers usually only have few tabs open, or don't mind clicking on a tab to make the damn X button appear, or would gladly abandon their beloved ergonomic mouse to buy a standard one with a mid button just to close tabs, of whatever the f... was going on in their minds when they decided to remove such an ESSENTIAL FEATURE!!! This change is WRONG! Nobody asked for it, nobody wants it, nobody likes it. The X button was not disturbing anybody. WHY must we tweak some f... about:config setting or ask in this Community for some css code to get back what should have never been removed!!!??? DO YOUR JOB, which is to make OUR user experience better, OUR, not yours!!!


Little help from my friends: After quick searches over a long time where I couldn't dedicate more resources to this, I came here determined to dig deep to find a solution. And I've found a few posts with answers from Cor-El. I followed his instructions in THIS post to configure a css file with the code that he provided in THIS other post (because I thought I didn't want the delay offered by the code he provided in the former post). Problem solved.

Now a question for Cor-El: Is it just me or the solution with the two browser.tabs settings does not work? It's the first thing I tried. I went from 50/50 to 200/200 to see if size matters. But no chance. Maybe there is another setting that must be activated for these to have effect? Or was their effect on the X button removed in newer Firefox versions (like the UX Destroyers really hate us)? Btw, I wanted to see how the delay thing would work, so I tried the code you gave in the first post, and it didn't have any effect. Whereas the code you modified for a guy in THIS post works perfectly. What could be the reason?

And 2 requests: - can you make some guide or pinned post about this, where you put together the info you gave in different posts? Something with your super easy instructions how to create a css file, and the two codes (with and without delay). And if the browser.tabs solution can still work, that too. All info in one single place, easy to find. - can you point me to a (possibly ADHS friendly) resource to more css codes for other useful tweaks, and to an explanation of what all about:config settings do? I like to tweak things to my needs. But I get overwhelmed if I have to read through tons of material. Thanks :)



Bonus Material, Little Rant part 2: It's good and nice that people help each other and I am thankful, but it does not need to come to this. Sure, I've read that the (ridiculous) reason behind the choice of making the X button disappear was to avoid accidental closure of tabs. But WHY taking for granted that we are some !diots who can't even use a mouse properly? And even if it happens once, we can still go to the damn "recently closed tabs"! But no, they had to remove the X button for all of us, to prevent a bunch of !%#@! from maybe sometime accidentally closing a tab. Why not just adding an option in the settings (NOT in some hidden "about:config") to let us choose if we want to have the damn button or not? Btw, a lot of these about:config tweaks are really useful and not dangerous at all and should imo be included in the normal settings. Keeping things simple and tidy does NOT mean reducing options. Unless you're Apple.

Please God-zilla let these [censored content] UX Designers read this post.


Amen and happy new Xear.

I don't want AI I don't even want to be near it. I don't want it lurking in the background of my browser. I don't want to waste a single processing cycle on even considering it. I never wanted AI, and they jammed it into my browser.

Currently, they popped up an ad for "AI Enhanced Tab grouping" and said that you can turn it off in the settings. I looked in the settings, and could not find such a thing. Searching for "Tabs" "Suggested" "AI" and other such related terms yields no AI things.

Why tell me I can turn something off in the settings if there is no setting to turn it off?

But that's just the start.

I want nothing to do with AI. I don't want to use a browser that supports it.

I WILL MAKE MY OWN DAMN BROWSER IF I HAVE TO. I QUIT GOOGLE, I'LL QUIT FIREFOX.

Mozilla used to be a safe-haven from all the bullshit other tech companies were pulling. And now this.

GET. AI. OUT. OF. MY. BROWSER.

I DON'T CARE IF IT'S LOCAL. I DON'T CARE IF YOU SAY IT'S SECURE. I DON'T CARE IF IT'S GETTING BETTER. I. DO. NOT. CARE.

GIVE ME THE OPTION TO PURGE AI FROM MY BROWSER OR BY FUCK I'LL FIND A NEW BROWSER.

All,

Noticed a major problem in Fire Fox, that must be corrected! I usually have 2-20 FF sessions open and 5-20 tabs also open in each FF session. FF used to let you see up to about 15 tabs, displaying them and responsively compressing the width of the tabs,to let you see what is open, but now it only displays 3 tabs, requiring you to actually scroll right or left to find the tabs open.

Totally unacceptable! This maybe OK for NEWBIES, but we pros and Developers need to see everything without scrolling to find it.

Otherwise I totally need a different Browser!

I regularly use a website which intercepts command-option-up and command-option-down for its own navigation. This is a central part of my workflow with this website, and without it it becomes completely unusable.

After updating to Firefox 140.0.4, these shortcuts are now used by the browser to switch tabs. I have not found any way to configure this. Am I missing some obscure way to do this or is this just impossible?

I imagine this change was made to support vertical tabs, but I'm not using those, so the command-option-left and command-option-right shortcuts make more sense for my horizontal setup. (I don't use those shortcuts either, though- I use ctrl-tab and ctrl-shift-tab!)

There are many tabs open in the firefox window. I'm closing the firefox. I'm opening it again.All tabs opened during the previous opening disappear.Either a new page or a single tab opens. The settings are set to "Open previous windows and tabs" (Image 1)


I go to "Firefox View" ---"Open tabs". (image 2) I see 2-5 windows there.In this case, there are 3 windows.WINDOW 1 is my main window with the tabs that should have been saved and opened when firefox was launched again. I close all tabs from unnecessary windows with a cross.Only window 1 remains. But when restarting, an empty or different window opens again.And again, there are a lot of unnecessary and incomprehensible windows on the list. Previously, a window with restored tabs from the previous session always opened. Question: 1)How can I restore the normal recovery of the previous session when restarting? 2) Tell me.I can somehow switch between windows (Firefox View" ---"Open tabs)(Image 1) Thank you.

Hello, I used to have Microsoft Teams as a pinned tab (in fact I think it was my first pinned tab), which I no longer need as I now have the Teams app on my computer. I have tried unpinning the Teams tab but whenever I close & reopen Firefox, it reappears - it doesn't show up initially, but will pop up 5-10 seconds after Firefox starts (my other pinned tabs show up straight away) - so I have to close it each time. Not a big issue I know but kinda annoying - any suggestions/solutions?

Window with 50+ tabs disappeared from history (again) and I cant restore the session

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)?
