Firefox Community Forum

This is the procedure I followed:

Close firefox

Copy previous.jsonlz4 file to the main level in the profile

It has all the tabs i used to have in it because I made a backup a few days ago

Rename the file to sessionstore.jsonlz4

restart firefox

I get the same single tab I had before i did this

when i go to history tabs, all that is there is the single tab i currently have

Appreciate your help/gary

mozilla won't save my previous windows and tabs even though i have that check marked in the settings. it's been like this for months. to keep them i've had to keep my pc on for moths. help, i'm thinking of leaving Mozilla because of this, it's incredibly frustrating to lose all my work every time.

Hi,

I have the following problem: Windows 7 crashed after coming back from standby. When I restarted Firefox it restored a 3-month-old session. The sessionstore.jsonlz4 file was missing in the profile folder. I searched for a backup in the sessionstore-backups folder; unfortunately all were too old. Windows Restore was not running on my computer.

Using EaseUS Data Recovery I found a recovery.baklz4 file from 10 days ago, tried renaming it etc. but Firefox won't use it for recovering. It is probably corrupt ...

I used https://www.jeffersonscher.com/ffu/scrounger.html but I get an error saying: Session history file contents could not be read?

Is there any way to repair the file or extract the URLs to use them manually?

Or any other solution is very welcome! Thank you very much!

As long as I have an incognito window open, Firefox will reopen old tabs everytime I open a new "regular" window, even if "Open previous windows and tabs" is unchecked.

I saw bunch of threads which suggest to enable "ctrl+tab cycles through tabs in recently used order". It does what I need, but in previous versions I used to press only ctrl+tab. While I was holding ctrl I could iterate over tabs via tab key. After releasing ctrl selected tab was chosen

It differs with current behavior where you press ctrl+tab and after releasing all keys pop up with tabs is still be viewed and you need manual action with space/enter/mouse click to open selected tab

Is there any way to use only ctrl+tab without any manual actions required like it was back in the days where after releasing the control key selected tab is opened?

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.

I have v138.1 and tab groups are not working. When I try and put one over another to create a group, it just sides away. I read this feature would be available on v137 and up after 5/6/25🤷🏼‍♂️

Running FF 138 64-bit on Win 10 Home, and tabs won't combine. When I move one tab over another, I get NO GLOWING RING, and the tabs just swap places as I move the first tab over the second one, no matter how slowly I move them. It doesn't work in Vertical Tabs, either.

I really appreciate this amazing new 'unloading' feature. It's just the function I need. However, I can't unload all the tabs I've selected. Only some of them are inactivated, and this problem occurs almost every time I choose a group of tabs.

Hi I read these articles and they doesnt help to resolve the problem https://support.mozilla.org/en-US/questions/1349609 https://support.mozilla.org/bm/questions/1206172 https://www.reddit.com/r/firefox/comments/ip88y7/firefox_is_preventing_windows_10_from/?rdt=53488

Problem: I have Win10. Firefox 107. I have noticed that if I have opened only regular/textual web pages in my tabs like news/articles then PC goes to sleep after specified time of inactivity. But if I open in the one tab some media content like videoclip/animation/movies and put media content on pause then PC doesnt go to sleep after specified time. PC goes to sleep only by manual command (Start>Sleep). Even If I close the tab with media content PC doesnt go to sleep after specified time. I should or totally close the browser with all opened tabs or manually select Start>Sleep.

Could you help to resolve this issue ?

On the screenshots are shown that some of firefox processes couldn't stop making some activity, every second they make some web request or disk operation. May be this is reason why PC cant go to sleep. But again, this is happen only or some media content is put on pause or some tab with media content has been closed.

Recently an update made it to where closing a tab group no longer works. It closes MOST of the tab group, leaving the last used one active along with a number to the right such as "+3" to show there are three more tabs hidden. This completely defeats the purpose of being able to close the tab group in the first place. In order to get around this, you have to click another tab to make it active and only then will the tab group you tried to close, actually close. Is there a way to disable this behavior so that closing tab groups actually works?

Assuming there is no fix, how can I downgrade to a previous version without losing all my settings, bookmarks, etc? Can I just uninstall the broken version and install the older version?

Thanks!

Hello everyone,

Like most of you, I'm aggressively attacked by advertising new tabs.

I'd like to have this: my tabs static, no movement, all fixed sizes, and no new tabs on redirects. If I need a new tab, I manually click the "+".-sign.

Fox tries to fit all tabs in, at the same time.

What I have tried so far is not working:

1. pinned tabs always get un-pinned at restart

2. pop-ups are stopped in Firefox own Settings

3. my settings in about:config: browser.uidensity = 0 browser.tabs.animate = false browser.tabs.tabmanager.enabled = false browser.tabs.allowTabDetach = false browser.tabs.tabMinWidth = 68 px dom.popup_allowed_events = False browser.tabs.loadInBackground = false services.sync.prefs.sync.browser.tabs.loadInBackground = false accessibility.blockautorefresh = false services.sync.prefs.sync.accessibility.blockautorefresh = false toolkit.tabbox.switchByScrolling = False browser.link.open_newwindow = 2 browser.link.open_newwindow.override.external = 3

Tabs still move, change size, and unwanted ones appear. :/

What settings should I change, add, or remove? Anyone more proficient than me, in about:config-programming?

Cheers!

I have used Firefox for 10 or 20 years and have not encountered this before.

New computer running Windows 11 Home. New Firefox install. If I am writing a message in any forum or social media site, and I need to look-up some info or the name of a place or product and I use another tab to do that, when I return to the original tab, Firefox reloads the entire page again instead of just returning me to the post that was being written without reloading the entire page. It can be a severe waste of time trying to find the post I was in the middle of once the entire tab reloads when the site is a busy place with lots of new and updated posts.

I've been through Firefox settings but did not see anything that seemed to be related to this issue, but perhaps the wording/description of the needed setting wasn't clear.

Are tab groups like containers i.e. isolated from the others, so thay I can access sites logged into different accounts for instance or separate browsing experience/cookies ?

TAB I am a new user of Firefox and when I open the browser today, I only had the use of one tab on each window. Yesterday, before closing for the night, I had multiple tabs. How do I get tabs so I can open multiple windows on each screen?
