Windows 10, latest version.

I hit a shortcut, I think, and heard the trackpad, then one of the three open tabs was isolated from the rest in a separate, almost chromeless window.

It's not in the taskbar pop-ups but instead has its own icon. In this 'chromeless' window there is no option to add a tab or window, there is no area to move it (I have to carefully use emtpy space in between buttons to move it). The top just fell off, that's basically it.

I have never seen this and have been using Firefox from the start way back when. I didn't install anything; this just happened as I was reading something and accidentally touched a key. Nothing changed, no settings were adjusted, nothing.

This option is not in the tabs menu or anywhere. I must say I kinda like it for this one 'tab' (which is a solo chromeless window) but I do need the menu and so on for productivity.

One of the screenshots shows this 'window', the other shows that 'window' is not part of the regular pop-up tabs in the taskbar but rather has its own icon, as if it were an app, in that taskbar.

What in the world is this? Can someone help?

I was excited to receive the new Tab Groups feature and am now disappointed that it's not working and I've 'lost' dozens of tabs.

Here's what I did: I created several groups by right-clicking and added tabs to each of the groups. Since it appears that only way to collapse a group is to "save and close group," I closed each group. Now they are all gone. When I right-click to create a new group or "add tab to group," the closed groups are nowhere to be found. Plus, I do not see a "list all tabs icon" on my toolbar to reopen the grouped tabs, which is what [article] says should happen.

Suggestions for making this work?

My tabs won't allow me to move/rearrange them. When I attempt to click and drag them around, they do not change order or escape the window. Window functions such as resizing, closing, and moving work as normal.

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

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.

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?

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! :)

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???

Hello, with older versions of firefox, it was easy to rank your favorite sites, which could avoid having 50 windows open at all times. Is there a way to do this? Thanks in advance.

Firefox crashed. I am trying to get it to how I had it before this. One of the problems is the new tabs thing. I know about CTRL-T, I have not used it. I have used the + on the tabs for years. I know, big deal, it's just inconvenient, interrupts my train of thought to switch, which is no big deal. But if anyone has a moment and can answer, it would be a blessing for me. Thank you.

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.

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 an ultrawide screen, yet my pinned tabs only occupy 1/3rd of my screen width before you have to scroll through them. How do I make this area wide and allow more than 27 pinned tabs to be visible.
