Firefox Community Forum

It says to drag and drop but that does not work. I minimized both windows and dragged the one tab to the 'larger' window and nothing happens. My email keeps opening in a new window and it never did before. It was a tab in my original window, and now it is so much harder for me to work.

With the latest update to version 155, I lost all my tabs.

In my Settings, Startup, I do have checked "Open previous windows and tabs". This has worked many times after shutdown and restarting.

But this latest update did not start ver 155 with all my tabs. Has anyone else seen this? On Win 11 laptop. Steveg

One of the more particular habits I have retained after switching from Chrome to Firefox is putting things in Tab Groups. This works great on Chrome as groups are more-or-less visual, and don't make a mess once you've closed them. On Firefox, however, I've noticed one really annoying thing: tab groups are saved in a giant list. Part of my workflow results in making Tab Groups with the same name as some of my bookmarks. When using the address bar to go to the bookmark will result in the tab group of the same name being brought up. For various purposes, this is decidedly unhelpful. In addition, when using the "Recent Tab Groups" drop down, it is rather annoying to see an entire screen's worth of tab groups being saved, especially when they all have the same(ish) name.

Is there a way to disable this saving of tab group names (and contents)? Clearing it out manually gets very annoying.

This is a followup to a previous post. I pinned a tab in firefox, and later deleted the webpage that was pinnned. I do not see a way to edit the pin, so I deleted it and created a new one with the new, updated webpage. I use the sync feature to keep all of my browser settings the same across three computers. I have tried multiple approaches to correct the problem. 1. turned off the sync and manually unpinned the tab, cleared the cache and browser history, checked to be sure I do not have the option to reload previous tabs turned on, booted in the mode that does not load any plugins, rebooted the computers 2. with sync turned off, after all of those steps, I opened the new page and pinned it on each computer. when I close the browser and reopen it on any computer, the original pinned tab returns. Turning the sync back on or re-enabling the option to sync tabs and history have no effect.

Is there a way, even if it´s within the configuration files, to change that pinned tab or block the old one from opening? Note that the website for the old and the new pinned tab is the same. the difference is the page itself. the old tab was [website].administration-landing. the new page is [website].admin-lp.

The is no reason why the old page, which no longer exists, continues to be pinned in the browser, but I can´t get rid of it.

Please help. Thanks.

Tab groups disappear when window closes, another group adds all the closed group's tabs. This is stupid. When I restart Firefox, or it decides to close, or restart, or whatever, if I have more than one tab group in the window, all the following groups disappear. And then they are added to the remaining group. So then I need to remove them from that group and put them back in the original . This is ridiculous. Why don't all groups remain in the same window with all their tabs intact and not redistributed?

Windows 11 , Version 155.0.1 (64-bit)

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!

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.

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.

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

Regards Sanjay

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 have the same issue as this person https://support.mozilla.org/kn/questions/1373153. I HAVE the "Open previous windows and tabs" option on, i also DON'T have the "Clear history and cookies when closing the window" nor "Clear history when Firefox closes" nor "Always use private browsing mode" on so the solution doesn't work for me. Firefox won't open previous tabs when i close the window. However upon restarting my PC i have noticed that when i start up Firefox, my previous tabs are opened. So it seems the action of closing the window is doing something to prevent Firefox from opening the previous tabs again.
