I am using the Firefox browser version 138. However I am not able to use the Tab Groups from firefox. I cannot add any Tabs to any group as there is no option for that.

I recently updated to Firefox 138.0.1 to use the new tab groups feature, which allows grouping and labeling tabs, as outlined in Mozilla’s support article (expected for all users by May 6, 2025). However, after updating, I don’t see the tab groups option when dragging tabs or right-clicking them. Has anyone else faced this issue? Could it be due to the progressive rollout, a conflicting extension, or a setting I need to enable? I’ve tried restarting Firefox and checking the tab bar, but no luck. Any community solutions or workarounds to enable tab groups would be greatly appreciated! Please share your experiences or fixes.

Hi, I have a large number of tabs and also have pinned tabs. When I click a link outside of Firefox (FF is my default browser) it always opens them at the end of my tabs (on the far right). I would prefer that the newly opened links open at the beginning of my tabs (the far left) but just after my pinned tabs. Is there a was to do this?

Thanks!

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.

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 often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio

Enter (paste) the URL into the Firefox address bar → hit Enter (paste and go) → open in a new tab every time. I want this to open in the same tab. Firefox version 145.0

OK after the code breaking yesterday here is the new code I got that works.

When I open a new tab, I can't automatically start searching anymore.

Here's a video: https://www.loom.com/share/ebcc8685187a4e2284cf40b75f7e134e?sid=9b0a3db3-fcac-4bae-9ff9-cdbe2b8b955b

Now, I have to click into the search bar to type. That's annoying.

Anyone know how to fix this?

I updated Firefox this morning to 139.0.4 on my Mac and now the '+' sign to add a new tab no longer appears on the tab bar. I can still add new tabs with Command T however.

Any suggestions on how to restore the '+' sign?

Thanks Dan

I'd like to ask about Firefox's behavior and settings. I'm using Firefox with vertical tabs (using an add-on), but it seems to be behaving strangely. The things that have changed since before are: 1. Open from pinned tab 2. Now opens in a new tab → Previously it opened in the same tab 3. Clicking on a newly opened tab opens a new tab again → Previously it would open pinned tabs/same tabs → in a new tab It has changed. I haven't changed any of my Firefox settings. Windows 11 Home 23H2 Firefox version 139.0.4 (64-bit).

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

I can't re-open a saved tab group. I saved it and closed firefox but when I returned I couldn't find where to access it. I see all of my saved tabs when I right-click on a tab and choose "Add Tab to Group", but when I move the tab to that group it just disappears rather than open the group. Any help would be appreciated! :)

It used to be that when I clicked ctrl+tab in the browser it would move through my tabs. Now, instead of moving to the next tab, it pops up a thumbnail preview and scrolls through those, instead. This is not useful to me. Is there any way to either revert the behavior or is there a new keyboard shortcut to quickly move to the next tab?

My Firefox browser just updated to version 143.0.1. When the browser reopened, there was an instructional page that opened in a new tab describing the Unload Tab function. I followed the instructions, right-clicked on the tab, the drop down menu appeared, but there wasn't an Unload Tab option. However, there was a Reload Tab option shown.

How do I resolve this? I'm using a macOS 15.6.1.

every time i go to open a link it puts me in a new tab, even trying to use the original way of changing the preferences in the browser itself doesn't work, it either opens a new window or new tab. i dont like new tabs or new windows created while searching or opening links, please help :/
