Google YouTube embeds itself in my List-All-Tabs Group and hops from Tab to Tab when I close the Tab it has embedded itself into. See the content of the Tab it is embedding itself into. I've written a description in the image. It's very annoying. Thanks!

Since the last update (I know that Firefox DE is a beta/semi-nightly release, I just want to know if this is my mistake or a bug), only my first firefox window has address bar, all the other windows don't. And when tabs are vertical, the rest of the windows don't even have a title bar. (This behavior doesn't apply to newly created windows) Also, non-primary windows also lose the capacity to resize the vertical tab bar. ¿Did I do something wrong or is this a bug?

There must be some setting I accidentally engaged by hitting some kind of key combination but there are the contents of 2 separate tabs on the FF window. Maybe it's some new 'feature' they added but I right clicked on the tab and nothing looked like it applied to this. What is it and how can I make it stop? I just want each tab to have the contents for that site. If you know what's going on, maybe explain it simply and I'd also like to thank you.

Upgraded to Firefox V.155.0 (64bit). Using Windows 11. The old version when accessing my Bookmarks allowed the option with a right mouse click to open that bookmark with the option "Open in New Tab". That option has disappeared. How do I get it back?

I had multiple tab groups which I had chosen to save and close. These tab groups have now completely disappeared and I cannot find them. When I began using Tab Groups, I had checked and there was no information stating that unopened tab groups would be deleted. I want these groups back. If I had known Tab Groups would disappear, I would have saved my tabs into a folder. The only Tab Groups that show up now are under "Recent tab groups". If tab groups are going to be deleted after a set period of time, it should be stated clearly in the tab group settings. It would also be really useful to archive them into a bookmarked folder so people don't unexpectedly lose hours of research.

On the Firefox mobile app, closed tab groups still count toward the open tabs count on some screens. This is frustrating as someone who likes to keep track of my open, active tabs accurately.

Not sure if this is an intended feature or not, but it is frustrating nonetheless.

Добрый день. После последнего обновления Firefox появилась проблема. Суть такая, При перетягивании вклдаки с одного окна Firefox на другое они не объеденяются. А переносится как новое окно. А в окне в которе переносится появляется синяя полоса и висит так бесконечно. Еще вчера, до того как я обновил до последней версии все работало нормально. Помогите решить проблему.

Google translate: Hello. I've encountered a problem after the latest Firefox update. When I drag tabs from one Firefox window to another, they don't merge. Instead, they move as a new window. A blue bar appears in the window being moved, and it hangs there forever. Everything was working fine yesterday, before I updated to the latest version. Please help me solve this.

Latest Stable Firefox, windows, over 4000 tabs. Overall Firefox works great for me. but when I restart it to install the latest versions etc, it only restores one active/loaded tab per window. Rest are restored, but in a closed/unloaded state. I usually have 5-20 open tabs per window, and hundreds more unloaded, it's how I work. How on earth can I get it to restore all the open/loaded tabs as they were, not in the unloaded state they default to?

Issue still occurs in a new install with no addons, default settings, under 30 tabs etc. Ditto Win 10 or 11.

Also, how on earth can I get official Mozzilla pages to use Dark Mode??

I am using the latest 155.0 build of Firefox on Windows

Edition Windows 11 Pro Version 25H2 Installed on 21-08-2026 OS build 26200.9278 Experience Windows Feature Experience Pack 1000.26100.360.0

Recently, probably around a few weeks ago, I have found that i am no longer able to reorder tabs using the mouse left click and drag to reorder.

The mouse is working fine and I am able to do the same reorder on the Chrome browser however it doesnt work on Firefox anymore.

The only way to reorder tabs is to use the popup menu and select Move Tab.

Kindly fix

I've been using the split view feature and really like it... however I constantly find myself doing the following:

Having a split view open with related pages, for example a list view in the left pane, and I want to open one of the items in the list view in the opposite pane, currently I have to:

1. Copy the url in the left pane 2. Switch to the right pane 3. Target the address bar 4. Paste the url 5. Load the new url

Ideally an additional 'open link in x' option could be added specifically when a user is in the split view, that will open the link directly in the opposite pane of the current split, so left > right or right > left.

My question is, is there is a way to do this already; I cannot find any reference to this in the docs.

"Open Link in Opposite Split View" would be perfect.

After today (Sep. 2, 2026)'s update, I noticed that the the plus "+" button for new tab is canceled. Instead, I have to now click right on the work function and click "New Tab" for a new tab. This revision is quite counter-intuitive. Could you please add back the plus "+" button for new tab in the next update?

Thank you very much.

Please can you (a) add to menus, or create a button, so users can see the tab groups they have created and (b) prevent upgrades to Firefox from deleting a user's tab groups.

Hi, firefox: 153.0 Yesterday evening I put 3 tabs in a "group tab" I decided to call "ARS".

This morning I don't see how I can re-open this group tab. Many topics speak about a button "list all tabs". That button doesn't appear in my firefox (even when I have 50 tabs open). I tried the "customize" menu of firefox and "got back to factory setting", but it is still not there.

When I go to the contextual menu of a tab, I see that I can add it to a new container or the "closed group tab - ARS". When I do so for a tab, it closes. (I'm not sure it's normal.)

At this point, I really just want to remove the tab group (because I already re-opened the tabs... it took 5s, fixing the problem is now entering the 20'...) but I don't see how I can do it. It appears nowhere. I even "deactivated the group tab" feature and then reactivated it... the "ARS" group tab still appears in the "closed group tabs" submenu.

Thank you for the information.

I'm really enjoying tab groups, but there's a feature that seems broken. After restarting my browser, I'd like to reuse the groups I've previously created. It appears you've added a menu option for that: "Add Tab to Group" -> "Closed Group" Unfortunately, selecting that just closes the selected tab, rendering those closed groups permanently closed. I can go ahead and add my tab to a new group with the same name, but that creates a duplicate item under the "Closed Group" menu. After using the feature for a bit, I know how quite a long list of duplicate items under a totally useless "Close Group" submenu.

OK - this keep happening on my firefox browser on my macbook laptop. I have a default firefox browser open with my 13 default tabs. Now when I have some app, like today specifically, the app for my voice caddy golf app. I open the app, do the update, and if I select any link that opens the voice caddy website, it opens it in a new firefox browser and tab, NOT a tab in my existing firefox with my 13 default tabs. So my default firefox gets trashed. In my firefox settings, I told firefox to open any new tabs in tabs, NOT pages. I also have open the last tabs open where I left off when I close firefox. What a pain. Tried several things to no avail. Why doesn't firefox have a setting (or the current setting do as I told it - open new websites in a new TAB, NOT a new browser.
