Using Firefox 145.0 (64-bit), "Firefox is up to date" on PC with Windows 11 Pro.

I was so pleased when Firefox's Group Tabs arrived. I often have about 12 tabs open to do Railway research. So I thought, Group Tab, great idea. Save a group of tabs as one tab. Instead of creating a Bookmark Folder and each time opening all bookmarks from said folder, what better way to do than opening one tab. Or so I thought. I also created a "SHIP" tab for my hobby in the shipping industry, so I could have two group tabs that could be collapsed making the tab bar tidier. I saved an closed each group tab then closed down my PC. Next on restarting, Firefox starts up automatically as chosen by me. Both RAIL & SHIP tabs reappeared without me doing anything. Great! However yesterday, I inadvertently opened another Firefox window, forgot it was opened. So when I shut down my PC, I closed the Firefox browser and then discovered the over Firefox window I had opened. Closed it shut down my computer. Of course when I opened my PC today, Firefox started automatically, but with the tab that I had open in the last Firefox window. No problem I thought, I will just open the saved Group Tabs. It was a problem, where are the Group Tabs saved? Could I find the location? NO! I looked in Bookmarks, all the various History lists, even the down arrow to list all tabs. Nothing, the Group Tabs are none existent. I have checked on the "about:config" section for Group Tabs and everything is enabled "true". So where are the Group Tabs saved? I have been with Firefox for around 14 years, often citing it as the best browser. But over the last five years I find myself using Chrome more and more. Chrome has Group Tabs which do not not need the users to save them, they are saved automatically, and are easily found on opening the Chrome browser. Why doesn't Firefox have this?

1. 1. Steps to reproduce

Open several tabs, in settings, check «ouvrir les fenêtres et onglets précédents», quit firefox.

1. 1. 1. Expected behavior

On startup, Firefox should reopen with the same tabs before shutdown.

1. 1. 1. Actual behavior

Firefox opens with one empty tab. Forcing me to got to «history -> recently closed windows -> restore» everytime I quit Firefox or shutdown the mac.

Is there a way to disable tab groups without going through about:config? Because I can't find it and there really should be...I have no idea how that feature works, I don't want it, but I keep ending up with groups unintentionally. I still don't know how I'm doing it. It's incredibly annoying and apparently incredibly easy to accidentally trigger and I'm sick of losing tab space to these random colored boxes for no apparent reason!

Every time I accidentally close Firefox I lose all my saved groups on reopening. I can see they are still there but cannot see how to open them. They are such a great innovation. Please make it easier to restore them from previous sessions. Going through a search history and restoring them one by one is hugely time consuming when they are already there and just inaccessible. btw, I tried using scrounger (via troubleshooting) but the "Save List" is greyed out.

Running on Mac OS 15.6.1

I use tab groups actively and would save much of my work in my ever-growing list of tab groups. I saw today that many of them had disappeared. I wasn't signed into Firefox and nor do I have any different profiles made. I see two tab groups that I made yesterday but none from before that. How could this happen? How do I recover so much of the work I had saved up?

I have vertical tabs turned on. Say i want to watch a movie, i press F11 or fullscreen to open it fullscreen. It makes the whole page fullscreen, but the vertical tabs remain still on the left. I want that fixed so that vertical tabs are hidden when its fullscreen.

Hi, I'm using Firefox 64bit (version 144) on my Windows 11. I've noticed that I can no longer drag tabs around or detach them. I would guess this started with the latest version because I could do that some short time ago.

I've already tried the following:

• Restart of the browser - did not help
• Restart of the computer - did not help
• Start firefox in safe mode (Troubleshooting mode) - did not help
• Tried changing browser.tabs.allowTabDetach - did not help

I'm not sure what could be the problem. Does anyone experience the same issue?

Maybe this is counter intuitive, and/or I don't understand pinned tabs, but is there a way to have pinned tabs visible in the tabs list, instead of hidden.

I find it very inconvenient in a variety of ways.
