the tab groups page i was shown by firefox says i should be able to group my tabs starting at the latest yesterday but my tabs still just move out of the way and refuse to group. i found container groups but they work nothing like the page showed. i have firefox version 138 and the tab groups was starting to be roled out on 137

Hi,

Is this new feature? Once I click on link with middle mouse button, that tab is opened and switched to it. Previous firefox versions only opened tab and thats it. It is very frustrating. I want open multiple tabs and then view those tabs. Now I have to, suppose I have 5 links listed in webpage:

I middle mouse 1st link Then I have to return to my previous page I middle mouse 2nd link Then I have to return to my previous page I middle mouse 3rd link Then I have to return to my previous page I middle mouse 4th link Then I have to return to my previous page I middle mouse 5th link Then I have to return to my previous page

If it is new DEFAULT, then please make ant option to switch back in about:config, thanks!

After the latest update, when I move a tab to the start of the line, it shrinks down to something unreadable. Before, it stayed the same size, with tabs all being the same size as each other, that size being dependent on how many tabs were open ONLY. How do I turn off this "Feature" ? I liked it the old way. I don't even know exactly what to look up to try to fix it.

I also hated tab groups, with my tabs suddenly moving around on me. I hate having to do research and maintenance every time I get an update. If this keeps happening, I may just stop updating or go to Chrome or something.

Windows 10, latest version.

I hit a shortcut, I think, and heard the trackpad, then one of the three open tabs was isolated from the rest in a separate, almost chromeless window.

It's not in the taskbar pop-ups but instead has its own icon. In this 'chromeless' window there is no option to add a tab or window, there is no area to move it (I have to carefully use emtpy space in between buttons to move it). The top just fell off, that's basically it.

I have never seen this and have been using Firefox from the start way back when. I didn't install anything; this just happened as I was reading something and accidentally touched a key. Nothing changed, no settings were adjusted, nothing.

This option is not in the tabs menu or anywhere. I must say I kinda like it for this one 'tab' (which is a solo chromeless window) but I do need the menu and so on for productivity.

One of the screenshots shows this 'window', the other shows that 'window' is not part of the regular pop-up tabs in the taskbar but rather has its own icon, as if it were an app, in that taskbar.

What in the world is this? Can someone help?

The latest firefox update introduced tab groups, something I've been eagerly waiting for ever since chrome released it!

However, my firefox's tab groups don't hide the tabs correctly. In the video demo I see that when you click on the name of the tab group, it should collapse all the tabs and hide them.

In my firefox, when I click the tab group name, the tabs don't get hidden as expected.

Here is a video that shows the bug I'm referencing: https://imgur.com/a/8ewW1a2

I tried disabling all my extensions and restarting firefox, also tried in private mode, and it still was having the same experience.

Are there any about:config settings that I might have accidentally changed that could be causing this?

Thanks!

Hello.

1. How to save a tab group without closing it? 2. How to make individual tabs in a tab group permanent? (So when you close a tab group only the permanent members are preserved.)

On Linux, clicking the X in the upper right hand corner of the Firefox display, or entering CTRL-W kills Firefox with no warning. It would be nice if there was an alert that came up asking "Are you sure if you want to kill Firefox?". Or at least add an option for this in Settings.

Before I updated to 142.0.1 when I had a tab group and closed it by clicking on it, all the tabs collapsed into the tab group tab and the only thing I could see was the tab group title tab. This was awesome! I started using it immediately and loved it. Since I updated the tab groups still work, but now, sometimes, when I click on the tab group tab to close the group I see the title tab, one of the tabs included in the group, and a "+2" or however many tabs are hidden. This pretty much defeats the whole idea of having the tab groups in the first place, which to me, was to hide ALL THE TABS under ONE tab to clean up my work area.

The image below shows an example. Note the "eBay" tab group is closed, and yet it shows the tab group tab (eBay), a tab in that group (eBay icon and "Order" with the X to close the tab), and then "+2" meaning there are two hidden tabs. In contrast, the "Simple" and "Web Work" tab groups are also closed and contain 4 and 9 tabs respectively, all neatly tucked under the one tag group tab for each group.

Why is this happening only on some tab groups, and only some of the time? How can I stop this from happening?

Recently the V-like icon/button appeared at the right-hand end of the top line of my Firefox windows. This Tab Search could be invaluable to some, but I have no need for it. If I start to get too many tabs I just use another window. However, I click on it constantly when I intend to minimize the window. I have been clicking on the - icon/button in EVERY WINDOWS APPLICATION since Windows began, and as it has ALWAYS been the LEFT-MOST item in the UPPER RIGHT CORNER I haven't had to think about it in decades. But now it isn't the left-most, that is now tab search.

Please, please, PLEASE provide a configuration option to remove Tab Search from the top line.

Thanks!

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

After i closed firefox with two windows it only restored the wrong tab and because most of the tabs were open some time ago i cant restore it from history too. Can i somehow restore them?

Since updating to firefox 142, ive noticed that if i move a firefox tab from my main monitor to my second monitor, it leaves a gap now where it used to be and doesnt shrink the other tabs back down like before

Its a bit difficult to explain so iv added a screenshot, the red arrow is where theres now an empty gap. I moved some tabs over to the other monitor and thats the gap it leaves

Any Ideas what is going on? About July 21st, 2025 I started noticing with a couple of browser tabs open, a new tab opens autonomously and flitters in the new tab name area, what "looks like a TagID", then closes by itself. I define "looks like a TagID" as something that looks like a tag at end of article link in popular newsletters I see, and appears in the url bar of the linked article.

The occurrence of the new tab happens when I open the browser, within 1 minute and occurs randomly during the session, perhaps every 20 minutes.

My first suspect/assumption is I am always signed into Mozilla when I open Firefox 141.0 (64 bit), processing an update now, Aug 5 2025. I have subscriptions to VPN and Monitor and I have sync (passwords and bookmarks) with my mobile instance of Android Samsung Galaxy phone.

My Desktop is set up as Windows 11 pro with one employer InTune acount for Microsoft but I limit that work to Edge browser.

Every time I open a new tab, another extra tab opens automatically with the following address: https://0.0.0.1/

showing this message: An error occurred during a connection to 0.0.0.1.

I already re-installed Firefox but this bug keems popping up.

BTW: I did not do a d*** thing. It just started yesterday and is extremely annoying!

When searching with google it always opens a new Tab with some not working Address. Whether i just search or click on pictures or look at a picture more in detail it always opens this tab: Look at picture: At this point it is really annoying and in the settings of the browser i don't seem to find a solution. Please help.

Hi firefox community,

I am using Firefox version 127.0.2 as my main browser on MacOS Sonoma 14.5. For the past few months, when using Firefox in Mac's full-screen mode, I've been experiencing an issue where one of the multiple open tabs unexpectedly displays in a separate window the moment I click on it.

This behavior didn't occur previously, and I believe it started happening about 3 months ago. It doesn't happen every time, but occurs a few times a day when I least expect it, making it difficult to identify the specific conditions that trigger it. I use a Magic Trackpad, and after switching to full-screen using the three-finger gesture, the moment I try to activate a specific tab, that tab alone displays as a separate window in full-screen mode.

Is it possible that a Firefox version update has changed this behavior? If this is a Firefox issue, is there a way to capture debug logs to have the developers investigate it?

Alternatively, if there's an option to prevent tabs from opening in new separate windows, that would be an effective workaround. Could you please let me know if such an option exists?

Best regards,

Mozilla tab keeps crashing (especially at YouTube) I was wondering if someone can help me find out why!

like tell me how to show the log or something to identify what is doing the crash.

Thank you in advance!

Looking for help to try and work out what is happening. Over the last few days, after powering up and browsing the internet everything works fine for a while. Main websites are Facebook, YouTube and continually clicking on bookmarked items. Normally only a few tabs are open at any one time. Then after some time, I open a new tab and get the

Gah. Your Tab Just Crashed message appear on the new tab and can not access any websites after this. The Close Tab, Restore Tab, Restore All Tabs do nothing.

I have to reboot the PC and start again.

I'm using the latest version 126.0.1 (64-bit).

• Tried running in Safe Mode, uninstalled Firefox and re-installed it, reverted back to 126.0 (64-bit) and same issue.

• I've cleared the cache and history

• Had Add Blockers, FB Purity and New Tab Override Extensions. Disabled these and still no success.

• I have AVG driver update installed and its telling me all the drivers are up to date.

• The problem seemed to start happening after an AVG update, so I have removed AVG Antivirus
