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.

MacOS 26.6, Latest Firefox. 153.0.3. Tabs are not restoring, since update to latest FF. Tab History shows old stale tabs, not the tabs that were present at time of exiting Firefox. I had closed those tabs. Is this an artifact of caching?

The active tabs should be stored at FF shutdown, not the old closed tabs prior to that. This Firefox quirk is both on my Mac Mini M4, and on my MacBook Pro M3. Kind of a pain in the neck to restore where I was. It's enough to make me reconsider this browser - which I have used for decades, using Windows, Linux and now MacOS.

I researched how to restore a session. It told me to go to History and click Restore Session. There is no line with that name, in my Firefox, on a Mac.

Under History the docs show 4 items before "Clear recent history...", I only have 1. Recently closed tabs 2. Recently closed windows 3. Search history. There is no Restore session.

The tabs that were open last session are in the start up window, and the check box is set to restore tabs and windows. But my tabs were not restored. (I only had a single window open.)

What can be done to "restore" previous behavior of Restore Tabs and Windows? Thanks for any and all assistance.

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.

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.

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?

Hey guys, so I always have a bunch of tab groups as it helps me organize my tabs. But every time I accidentally close Firefox or my pc resets, all the tab groups are gone. UNLIKE google chrome where, even if I close chrome they will be on the toolbar for me to open again. So could you please add this feature on firefox as well because this is getting very irritating because I have to open the individual tabs again and again? Thank you.

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.

HOW DO WE NOW " SET CURRENT TABS ON OPENING BROWSER "

YOU ELIMINATED THAT SETTING THE MOST IMPORTANT !!!!!!!!!!!! YOU ELIMINATED THAT SETTING THE MOST IMPORTANT !!!!!!!!!!!!

I am using Ubuntu 22.04. Firefox version is 143.0. IIRC firefox recently updated. I have the setting "Open previous windows and tabs" checked. Until very recently it has always worked but now when Firefox is closed all tabs are lost and don't appear when reopening Firefox. How to fix???

I've been using tab grouping and it is really helpful.

But this morning when I created a new tab group called "MISC" I was unable to add any tabs to it.

1. I noticed that this new group happens to be the 11th group I've created. So I'm guessing that there may be a limit of ten groups. Am I right?

2. And now, some hours later, I see that the new MISC group does appear on my tab bar, but one of my old groups, TECH, has disappeared, but its contents seem to have been added to the MISC group.

When I click on a bookmark, FF opens it in the current tab, overwriting the site I had open. I have to add a tab, then click on the bookmark to have it in a new tab. This is an annoying extra step. How to I change it? I already tried the open links in new tabs instead of windows. Makes no difference On or Off

I am using tab groups and suddenly they all disappeared. There is no hint or trace of this function, not even in the tab pulldown menue. I checked the internet, I restartet Firefox several times, I restarted my notebook (Windows 11), I checked about:config (tab groups are enabled). I even reinstalled firefox - it seems like tab groups never have existed. What might have happend - and how could I get that feature back?

Thank you in advance Wolf

I want the browser's tab bar to display like the homepage, instead of disappearing after opening a webpage tab bar. I don't know if I can accurately express my meaning, but I will attach two pictures

Since yesterday, some of my tab groups don't fully collapse when the group tab is clicked. Instead, one tab in the group remains fully expanded, followed by a number indicating how many other tabs are in the group. A screen shot is attached.

Since I enabled tab groups some weeks ago, tab groups have behaved as expected. When the group header is clicked, the tabs in the group spread out to be visible and clickable. When the header is clicked again, all tabs in the group collapse entirely behind the header tab.

Most of my tab groups are still behaving this way. But new groups are now displaying one full tab plus the number, no matter how many other tabs or tab groups are already occupying the window.

Since the behavior is inconsistent, it doesn't seem to be a setting. Is there any fix?

Hi Was told to ask new question off of this tread. https://support.mozilla.org/en-US/questions/1314940#question-reply

I have similar issue. Have file that has all the tab history, but can't get Firefox to recognize or use it. The scrounger pulls up everything so the file is good it seems.

Why can't, or how do we get Firefox to use it?

Thank you
