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 ?

Let's say I have a group of 5 tabs. If I open a new tab from any of those tabs, I want that new tab to end up at the right of the group but not part of it.

Can I do that?

When right-clicking on a tab and choosing Move Tab, the option for a new window has gone MIA from the tab context menu. It still shows To Start and To End. Is there a config option that got changed?

Recently updated to Windows 11 after Windows 10 stopped getting supported. After putting down several smaller issues on my own, I can encountered something I cannot fix on my own. Currently, I cannot detach, reattach, move tabs (With the exception of moving tabs with the right click menu). I could do all of these on Windows 10. I have already tried the browser.tabs.allowTabDetach setting in about:config to no success. I am starting to suspect it is a problem with windows versus a problem with Firefox because of an earlier bug where I couldn't move the windows entirely without enabling the Snap Windows function in my settings.

I have a new mac, an M4 mini, and I set up Firefox the way I want it (the biggest ask has always been getting a bookmark to open in a new tab). Two days in, sometimes a bookmark opens in a new tab, and sometimes it doesn't. I have nothing else set up except for an ad blocker. I have not changed my OS from Sequoia to Tahoe yet, I strategically delay. It's not the end of the world. But I had strange things happen with Firefox on my other mini (an M2) in the last 6 months and I had to abandon Firefox and use Safari, which I hate. But that's a whole other topic. I've used Firefox forever, and it's my fave, and little things like this bug me. What am I missing? I set the option to False, and then reset it to True, and sometimes it works as it's supposed to, and sometimes it doesn't. So to not overwrite an open tab that has something important, I just automatically click on the 'command' key when selecting the bookmark. It's staying on my selection to 'true' and I've set it to false and then set it back to true, and restart Firefox, and I still get inconsistent results. There's nothing else that could be conflicting with this. I don't get it. Like I say, Firefox on my other mini just totally became unreliable and I had to use Safari. Any ideas? Thanks!

Before the update, I could use "cmd+shift+[number]" to open a new container tab. Now, nothing works. "cmd+t" opens a tab with "no container", which is completely different.

I already tried going to "about:keyboard", but opening a new container tab isn't even listed as an option.

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!

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!

PROBLEM: Pinned tabs are useful, but if I have more than one Firefox window open and I close them in the wrong order, the next time I open Firefox, my pinned tabs are gone and I have to pin them again.

SOLUTION: Pinned tabs should be able to be permanent so that they will re-open no matter which Firefox window is closed first. Is there a way to make this work?

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 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🤷🏼♂

Hello,

I dislike the Group Tabs feature. So many times I've accidentally created a Group Tab and then had to figure out how to un-group them.

I've tried to change the value of the "browser.tabs.groups.enabled" preference to false, but it doesn't stick; after restarting, the value is always back to "true".

What’s up with this?

Thanks, Andre’a

I really can't add to my Summary other than it's a fairly recent issue, started in May 2026, possible April. About.config is set to False. I hope some has a solution - it happens when I'm dealing with live incidents.

When I click a link I always want it to open in a new tab. How do I do this without doing a right-click and selecting "Open in new tab"?

I want it to open in a new tab when I simply click the left mouse button.

Hi there! I find the new sidebar (on the left for me) a great addition but is there a way to reverse the "top to bottom" tabs displaying order?

Not a way to move tabs, but a setting allowing, when opening a new tab (Ctrl+t), to place (and display) the icon on top of the tabs icons pile, not at the bottom.

I get that it's the opposite of the normal reading direction, but it's rather unnatural to go looking at the bottom of the screen for recently opened tabs, IMHO.

Thanks in advance if you can address this, or show me where I can find such setting.

Best regards from France, Jc

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?

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.
