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?

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 :/

Firefox has a feature where, if you select a tab and drag your cursor downwards while still pressing down on it, it will open that tab in a new window. Is there any way to disable this? I am frequently opening tabs in new windows when I'm just trying to view them and it drives me mad. I never use this feature intentionally- I am constantly using on accident due to quickly moving my cursor away from the tab bar to view the tab I just opened. Thank you.

Before I updated to 142.0.1 when I had a tab group and closed it by clicking on it, all the tabs collapsed into the tab group tab and the only thing I could see was the tab group title tab. This was awesome! I started using it immediately and loved it. Since I updated the tab groups still work, but now, sometimes, when I click on the tab group tab to close the group I see the title tab, one of the tabs included in the group, and a "+2" or however many tabs are hidden. This pretty much defeats the whole idea of having the tab groups in the first place, which to me, was to hide ALL THE TABS under ONE tab to clean up my work area.

The image below shows an example. Note the "eBay" tab group is closed, and yet it shows the tab group tab (eBay), a tab in that group (eBay icon and "Order" with the X to close the tab), and then "+2" meaning there are two hidden tabs. In contrast, the "Simple" and "Web Work" tab groups are also closed and contain 4 and 9 tabs respectively, all neatly tucked under the one tag group tab for each group.

Why is this happening only on some tab groups, and only some of the time? How can I stop this from happening?

There are many tabs open in the firefox window. I'm closing the firefox. I'm opening it again.All tabs opened during the previous opening disappear.Either a new page or a single tab opens. The settings are set to "Open previous windows and tabs" (Image 1)

I go to "Firefox View" ---"Open tabs". (image 2) I see 2-5 windows there.In this case, there are 3 windows.WINDOW 1 is my main window with the tabs that should have been saved and opened when firefox was launched again. I close all tabs from unnecessary windows with a cross.Only window 1 remains. But when restarting, an empty or different window opens again.And again, there are a lot of unnecessary and incomprehensible windows on the list. Previously, a window with restored tabs from the previous session always opened. Question: 1)How can I restore the normal recovery of the previous session when restarting? 2) Tell me.I can somehow switch between windows (Firefox View" ---"Open tabs)(Image 1) Thank you.

I recently decided to try vertical tabs in Firefox, and can't find a way to search these tabs as I could when they were horizonal, with the downward pointing arrowhead. If this is a feature, please let me know how to add it to my sidebar, and if not, it would be great if this feature could be developed. Thanks!

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!

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.

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'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).

For some time, maybe 3 updates ago, when I open Firefox with my many tabs, I have this problem. The first 3 tabs that I close leave a blank space the width of 3 tabs on the tab bar. After that any new tab opens to the far right spot at the end of the blank area. This happens in a private window too (extensions closed). After I close a session, then reopen later, all my tabs are still in place but the first 3 that I closed reappear where they were at the start. Strange.

I have a strange problem and cannot find any reason for it.

On two different machines (with the same Firefox account, same extensions) I'm using tab groups, also in multiple windows (restoring them after launching Firefox).

In one installation I can close all tab groups without any problem.

In the other if it's the last open group, trying to close it (by clicking its header) opens a new, empty tab instead.

I'm pretty sure the settings of both installations differ but I cannot find any setting that would cause this behavior. It's especially annoying because with many open tabs I have to scroll through all to find the group I want to open instead, open it, scroll back to the other group header and close it.

Any pointers on where to start looking?

There is no longer a 'search tabs' symbol at the top section of the Firefox browser page since I switched to the vertical sidebar for tabs and after searching for help the Mozilla suggestion of ctrl+B just tries to search bookmarks. Please can you help as I have many many tabs always open and use this symbol frequently. Thankyou

So I change the tabs maxim length (i chose 225) because i hate not seeing the name of the tabs that i have open, now i have 10 tabs on my sight on my monitor, i usually open a LOT of tabs for youtube videos or so on, and have a constant of 40+ tabs open

the issue is when i scroll through the tabs with my mouse wheel, it jumps 10 tabs at once, now i see the arrows on the side of the tabs, my monitor is Ultra Wide so is annoying to keep pressing that Scroll backwards & Forwards button especially when the speed is to slow, while my mouse wheel speed is in 10 tabs TO fast!

Is there a way to change the Speed of the mouse wheel scroll tabs ? something in about:config ? or a Add-on?

I have vertical tabs enabled and I'm trying to access the tab overview menu to close duplicate tabs. Unfortunately I can't find this menu anymore. If I disable vertical tabs, I can see the icon in the top right. How do

How do I access the tab overview menu when using vertical tabs?

Thanks

Recently updated to Windows 11 after Windows 10 stopped getting supported. After putting down several smaller issues on my own, I can encountered something I cannot fix on my own. Currently, I cannot detach, reattach, move tabs (With the exception of moving tabs with the right click menu). I could do all of these on Windows 10. I have already tried the browser.tabs.allowTabDetach setting in about:config to no success. I am starting to suspect it is a problem with windows versus a problem with Firefox because of an earlier bug where I couldn't move the windows entirely without enabling the Snap Windows function in my settings.
