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 Firefox I have repeatedly pinned four tabs for websites that I use frequently. The pinned tabs disappear at unpredictable times, not necessarily when I re-open Firefox.

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.

I use the tab groups feature a LOT at work and have more group than available colors. I'd like to also be able to specify custom colors that suit my preferences (I like chartreuse for its high visibility).

Hyperlinks keep opening in new windows, not in the same/existing window where they were selected. Issue is not unique to Google Search results and occurring across multiple websites. At wits end trying to figure this one out. I have deselected the "Open links in tabs instead of new windows", turned off all extensions, and uninstalled & reinstalled Firefox. Issue is still occurring. Attached is image of my tab selections showing all turned off.

I use tab groups to save work sessions so I can easily close and reopen them when I need them. I typically use the downward arrow to see all of my tab groups, however, when I opened my laptop today, there are only two tab groups there and no "show all" option. When I opened my laptop today, I did see that Firefox had been closed unexpectedly and the restore sessions option, which I used. The two tab groups I had open when I left my laptop opened again when I used restore sessions, but now those are the only two tab groups I seem to have. How can I get back all of my other tab groups?

I can not seem to find the button to open a saved, closed tab group. I have googled, and there seems to be a lot of people with the same issue. However, None of the information given under those forums provides me with a clear, easy solution. Please help.

Until the most recent version(s) (at least through 148), if I have multiple windows open, the restore tab hotkey (control + shift + t) would open a closed tab in the previous window it had been closed in. Now, it opens the tab in whichever window I currently have focus on. It also used to remember the tab's previous location with regards to order among other tabs; now it opens it at the end of all tabs.

Example: I have two windows open, window A and window B. Window A has 5 tabs; window B has 10 tabs. I close tab 3 of Window B.

Old behavior: Pressing restore tab hotkey (control + shift + t) would cause the closed tab to always open in window B regardless of which window currently had focus, and would open it between tabs 2 and 4, as tab 3 again.

New behavior: Pressing restore tab hotkey (control + shift + t) will now cause the closed tab to open in whichever window has focus, A or B, and open as the last tab; for instance, if I am in window A, it will open as tab 6, if I am in window B, it will now open as tab 10, instead of tab 3.

Is there any way to restore the old behavior? At the very least, to get the windows to separate out the restore tab lists? I don't want tabs restoring to incorrect windows.

Hello,

I'd like to report an issue with a recent Firefox update.

Since one of the latest updates, the "Close all duplicate tabs" option has disappeared from the tab list menu (the menu opened via the small arrow on the right side of the tab bar). I've looked for it elsewhere in the UI and haven't been able to find it.

System info:

Firefox version: 154.0 (64-bit) Operating system: Windows 10 Professional, version 22H2 (OS build 19045.7663)

This feature is particularly important to me because I regularly keep a very large number of tabs open — often several hundred, sometimes over a thousand — and being able to close all duplicates at once was essential for managing and cleaning that up.

A couple of things make me think this may be an unintentional regression rather than a deliberate change: Mozilla's own support article on the Tab overview menu still lists "Close all duplicate tabs" as part of this exact menu, and I couldn't find any mention of its removal in the release notes for the two most recent versions (153.0.3 and 154.0). That said, I haven't found an existing bug report that matches this, so I wanted to check here first.

I'd really appreciate help with the following:

Why has this option disappeared from the tab list menu? Is this an intentional change, or a bug/regression? Has the feature simply moved somewhere else in the UI? If it's a bug, is there already a tracked report I should follow, or should I file one?

Thank you in advance for your help — this was a feature I relied on daily.

Hi All,

I had several tab groups. I open and save and close them every day. but since yesterdayI cant find them at all. If I create a new tab group it appears but those old tab groups not! I've tested troubleshooting mode but noting.  

Firefox 154.0 (aarch64), macOS 26.6.2.

dear sir/ mam:

like in safari, i had pinned the websites (as tabs) i visit regularly.

when i restarted the browser, all tabs were gone.

i have been using this feature in safari since a decade and no pinned tabs have been lost.

please guide.

I'm wondering if there's a way to MOVE open browser windows in the way that you can move tabs around within a window? I do a lot of research and I work this way in order to go back to a particular subject and continue where I left off. Right now I have 20 windows open with any where from 5 to 12 tabs in some of these windows. When using my pointer I see only the tab that was opened in a particular window when I closed FF. I tried holding the pointer and dragging the open windows in the task bar...but no luck.

I guess I'm asking if there's anyway I could get a quick view of what every tab in every window open actually is, or perhaps use search words to find what I'm looking for?

Thank you any response ~~Bonnie

It has happened recently that when I clicked on something Firefox takes me to a different window opens in a new tab and I had to go back to the tab that I was on for that click. Is this something new that Firefox does to generate ad revenue?

hallo zusammen wo finde ich in firefox eine funktion, die mir die zuletzt angesehen und geöffneten tabs wieder herstellt?😐

in den einstellungen ist "Vorherige Fenster und tabs öffnen" angehakt.

es kommt aber wiederholt nach updates dazu, dass die letzten fenster und tabs nicht wieder geöffnet werden, sondern nur 1 tab mit der festgelegten startseite.🤷♂

muss ich mich damit abfinden, dass die letzten tabs hin und wieder im nirwana verschwinden? oder gibt es auch dafür einen tipp für laien?🙏

I keep asking. I don't want to, but I am going to use another browser that I don't like, that does have the + as I keep hitting the y key to open a new tab. I am not well, cancer has me. My eyes are bad, and I could use some help, Thank you.

Firefox crashed. I am trying to get it to how I had it before this. One of the problems is the new tabs thing. I know about CTRL-T, I have not used it. I have used the + on the tabs for years. I know, big deal, it's just inconvenient, interrupts my train of thought to switch, which is no big deal. But if anyone has a moment and can answer, it would be a blessing for me. Thank you.
