Hi there

am on Win 11 with Firefox 139.0 (64-bit)

Up until recently, when I right clicked open in new tab, the browser would open that tab at the end of the tabs

Now it opens next to the source tab

I have adjusted about:config so many times to try and get it to work but no joy

my settings are (based on wanting to open any tab at the end) browser.tabs.insertAfterCurrent = false browser.tabs.insertRelatedAfterCurrent => false

Is this a known issue? Its driving me nuts as I keep losing tabs. Thansk

Hi there,

I have just updated to version 139, and I still do not have access to tab groups on one of my devices. I have the devices synced and fully updated. I have tried restarting firefox many times, I have gone into the config and set browser.tabs.groups.enabled (already true), browser.tabs.groups.smart.enabled to true, and browser.tabs.groups.optin to true. still nothing and only on this computer. see attached images as proof of software version and config settings. Someone please help! I have been dying without groups after moving from chrome a year or so ago, so when I found out they were added I was so excited.

Running FF 138 64-bit on Win 10 Home, and tabs won't combine. When I move one tab over another, I get NO GLOWING RING, and the tabs just swap places as I move the first tab over the second one, no matter how slowly I move them. It doesn't work in Vertical Tabs, either.

Hey, in other browsers when you type something in the address bar, for example "youtube" you get suggested searches/links and if you click on them with middle-mouse button (Firefox shift+Middle-Mouse button) you open them in a new unfocused tab and keep the search menu open and can keep clicking on suggestions.

In Firefox the search menu closes after each opened tab and I want it to stay open without having to type in it again after each opened tab. The new tab is unfocused as it should be, I just want the search bar to not clear itself.

I do not want to have to create hundreds of bookmarks for suggested searches.

tabs I do not have open appear below search window, how can I stop that’ for ‘Firefox?

Sites I do have open are at the top, that's all I need, this extra vector of links I don't want now clutters by screen and may be using my resources.

the tab groups feature doesn't work. WHen i drag one tab onto another, nothing happens, other than the tabs go back and forth. Can't put one tab over another and no group is created.

Please consider optimizing the resource management while minimizing a tab group. This would be an amazing option to be included. If its already present in the tab groups inherent workflow, please add more documentation about its effects and more. Maybe adding optional workflows for a scenario of usage like a energy efficient usage button for a tab group is a great idea.

I seem to have accidentally set up tab-groups, on desktop. Probably I fat-fingered a shortcut to group some tabs. This is a function I'll never intentionally use — since I'd rather not cut off my fat fingers, is there a way to permanently shut off tab-groups?

Thank you kindly.

Sometimes when I click on a tab I go to that tab but the tab itself gets moved to the right end of the tab bar, I have no clue what causes this, and it's typically infrequent enough that I've mostly forgotten about it before it happens again

I've switched to vertical tabs as soon as they became available, and although I prefer using them, at the moment there is an annoying issue with them. If you have one or several pinned tabs, clicking one of them does show the corresponding page, but you can't interact with it until you click into it. To reproduce, have at least one pinned tab and a normal one. If you click on a normal tab and then press "Tab", the focus will start jumping between elements that are focusable. But if you click on a pinned tab, pressing "Tab" will first jump through the tab bar a few times before finally getting to the page: First, the tab itself will get the focus, then the "New tab" button, then the "Customize sidebar" gear icon, and only then does the focus move to the page itself.

What's annoying about it in practice is that one of my pinned tabs is a site that uses keyboard shortcuts for interaction, and whenever I click on it and start pressing keys, nothing happens. Then I have to click into the page once to move the focus to it, and only then does it become usable again.

So, it would be great if pinned tabs would behave the same way as normal ones, immediately focusing the page when clicked.

Browser stopped showing all opened tabs across toolbar. Used to be able to see & toggle between several open tabs (websites) at the same time. Now browser only opens 1 bookmark tab & cannot even use backup button to see any previous tabs. Firefox 138..0.4

I'm using 138.0.4 in MacOS 15.5. When I updated to MacOS 15.5 Firefox only saved one of three windows. The MacOS toolbar at the bottom no longer gives me the option of opening another window, or selecting another window already open. I like the old behavior better.

I am very used to switching tabs by using the keyboard so I usually do Ctrl+tab and I have it set to recent order (which makes sense to me because most of the time you switch back and forth between two or three tabs) to navigate between tabs. In some recent update, some tabs became unreachable by using this keyboard shortcut, as no more tabs are displayed nor do they appear when you reach the end of the list, forcing me to use the mouse to look for the tab (please see screenshot attached).

I was hoping this had a workaround or if it is a bug I would like to know how to report it.

Thank you!

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

I lost all my tabs groups with the the update to release date for Firefox 138.0.4 on the 2025-05-19. Tab groups are still configured but my sessionstore.js is missing. I notice that there is a backup in Session-store backups dated the 2025-05-19 so I presume the tabs groups are still stored there. Can anybody suggest how to get the tab functionality back? I'm hesitant to just restore the sessionstore.js -- the actual tab group functionality is gone. I can't even recreate the groups.
