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?

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.

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.

Hello,

I recently had an issue where I accidentally closed Firefox in such a manner that it did not save my Tab Groups... Should that be possible?

I am trying to recall the steps to cause this to happen. At the time I had two Firefox windows open: one with all of my usual tabs, and one with a single tab open. I believe the steps were as follows...

1. Closed Firefox window with all of my usual tabs open
2. Closed Firefox window with the one tab open
3. Opened Firefox, and the session with one tab open came up
4. Closed that session
5. Opened Firefox again, one tab open
6. Checked the 'List all Tabs' - Recent tab groups, Show All - This was blank

I assumed that Tab Groups would survive sessions being closed like that like how Bookmarks do, am I wrong in that?

I discovered tab grouping and find it moderately useful. There was an update, now I cannot group and tabs. They simply will not. Spent a few hours with ChatGPT trying a range of things. Al settings are right for tag grouping, but it simply does not happen.

Every time I start Firefox, some of my pinned tab favicons will show an unread dot (although not consistently), even though there may have been zero changes to anything in that tab. Gmail is especially bad about this, making me think I have a new unread email when all of my emails have been read. How do I fix this? I looked in the Tab settings for Firefox and don't see anywhere I can change a setting.

It used to be really easy. I have Firefox set to open lots of tabs when starting. If I then decide I don't want some of those tabs any more I simply closed those tabs and then went to settings and there was a button to save my Homepage. Then I closed Firefox and next time I started it all my tabs, less those not required, would open. Now that doesn't seem to be possible.

How do I just get rid of the not required tabs? And, in the future, if I want to add more tabs how do I get them to open next time I start Firefox?

Ik wil graag verschillende mailadressen van outlook willen openen: https://outlook.cloud.microsoft/mail/ Ik gebruik daarvoor containers maar het werkt niet. Als ik een een bookmark open in een specifieke container wordt de laatste geopende mailaccount getoond. Als ik denk het met Pin allemaal te hebben ingesteld en ik sluit de PC af dan is het bij opnieuw opstarten allemaal weg.

Personally I do not like the new firefox. My bookmarks will not open in a new tab automatically when needed, it over rides the current tab that is opened. Additionally I am constantly being bothered with a unrelated pop up every time I open a new tab. and the Firefox logo used to appear so that you could click on it and get to firefox's home page. New version is horrible. may have to abandon and use another browser.

I open firefox. Homepage is there. I open a new page. A new screen appears which completely obliterates the former screen. As if I had just opened the internet. With the next page I go to, it is the same. Previous screens masked. And so on, and so on. Instead of separate tabs appearing at the top of the initial page

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.

Numerous tabs appear whenever I open Mozilla. I have used them at some time in the past, but never all on one occasion. SOME WERE LAST USED AT LEAST SEVEN MONTHS AGO.

Related may be that sometimes when I follow a link on one website, the destination appears on my screen as a new opening of Mozilla. The previous site(s) are completely obscured

Is it a bug? Is there a way to turn it off? It's too easy for me to accidentally close a tab this way. I cannot reproduce in Troubleshoot Mode but I can't find any setting or installed extension that seems to control it.
