Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

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....

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!

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

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.

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!

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.

I have many tabs open at the same time and I'm noticing tabs from Urban Dictionary in particular are automatically changing to suspicious sites, quite a few porn sites in fact.

Is this something Urban Dictionary is doing to direct viewers to sponsors or is there a bug in my FF browser?

I have pinned various shortcuts in the New tab to link to websites I frequently use. I use two different laptops and both are configured the same. However the New tab randomly clears the pinned shortcuts. I have attached two screenshots illustrating the changes.

I'm not aware of anything I do that caused the shortcuts to be deleted. When they are pinned I think they should be there permanently.

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.
