sense I leave tabs open that I want to watch latter i would like to be able to see the video before I close the tab: when i open it says the tab that is taking the most memory is "https://youtube.com (15668)" I tried clicking and right clicking but no functional it locate or go tab then i opened the drop down the search bar set it to tabs and typed in "https://youtube.com (15668)" but it showed no results.

In early June 2025 I finally ditched Windows 10 for 11 and I've been a Firefox user since practically the very beginning of Mozilla.

Now, I notice that the "Restore Previous Session" button in the drop-down of the FF menu is missing. Additionally, I discovered late in the game that Mozilla DID listen to me and gave us the ability to "name" or "tag" an entire window in the browser. This was a HUGE boon to productivity as I'm constantly toggling from window to window to tab to tab.... Now, with the most recent update this ability seems to have disappeared....

I tried to add maps.coogle.com to a specific container. this ends opening maps forparts of a second in this container displaying the cookie content page. regardles if a agree or not, it opens the cookie consent page in a new tab (looping forever) is there a way to add a site to a specific container using a config file? is here a way to add a site to a container, without having the subsites after the TLD, in the URL

Kind regards

How can I move a tab to an open window? I know there is a function in the pull down menu to open the tab in a new window, but I would like to move the tab to a window that is already open. Google and Brave Chrome have a seamless, easy way on the pull down menu. I use it all the time, but I want to keep Firefox as my default browser. Thanks!

I'm on the latest FF 140.0.1 on Linux and I adore tab groups, I'm using it more and more to organize my browser windows. I am using the default (horizontal) tab group layout. Because I have a lot of tabs in the window, I collapse each existing tab group and sort tabs between tab groups.

I can move a tab into an expanded tab group with drag and drop. But I tried dragging and dropping a tab onto a collapsed tab group, even holding it over the collapsed tab group to see if that would work. Nothing seems to register, is it possible?

I would like to move a tab by drag and drop without expanding the collapsed tab group and move the window focus to the next tab. This would save time when I am organizing tabs!

The alternative is to Add a tab to a collapsed tab group, which also expands it and consumes horizontal real estate, forcing me to scroll (further) to return where I was organizing tabs. So I collapse the newly expanded tab group, scroll back to the next tab I want to organize into a different tab group, and repeat but this causes a lot of scrolling navigation to my workflow. It makes complete sense and I really like using menu navigation to add tabs to a specific group because it is discreet and I wish I could move tabs with the same method.

I searched Settings > Tabs and then about:config for browser.tabs.groups.* (and then every preference with tab in it) and couldn't find anything that made sense to me.

Thank you for any help!

I really like the new tab group feature and I wondered if it would be possible to isolate tracking within a tab group. I didn't know about tab containers yet but it seems like a great feature to have the option to have a tab group also act as it's own tab container.

Are there any plans for integration between these two features?

Hi,

I started using the 'Vertical tabs' option to manage my tabs. I prefer it over the horizontal bar. However, I noticed that when going fullscreen (F11) the vertical tabs are not removed. This is different from horizontal tabs, which are removed from the UI when you press F11.

I think that's because vertical tabs are tied to the sidebar altogether. Is there an alternative to have the vertical tabs work the same as horizontal tabs?

Horizontal bar behaviour in fullscreen:

- The horizontal bar disappears when going fullscreen (F11) - The horizontal bar reappears when hovering the mouse over the top of the screen (which is great!)

Vertical bar behaviour in fullscreen:

- The vertical bar does not disappear and gets in the way of the fullscreen (F11) experience - Checking the setting "Expand sidebar on hover" does not replicate the behaviour of the horizontal bar reappearing upon hovering the mouse. Instead, the smaller version of the sidebar remains and it expands to it's full size when the mouse hovers over it - The only option is to remove the sidebar altogether, which means going back to horizontal tabs

Can someone tell me why it is if I'm on a tab and either accidentally or on purpose click the home icon the tab will shut down, and be replaced by the home page? What type of backwards reasoning went into that feature? I've had this happen numerous times without intent, and sometimes with the intent to hit the home button and either way the same thing happens. If it weren't for the browser keeping a history, there are times I would be just out of luck, and have to suck it up. This is not a feature I want in a browser. Instead hitting the home button should forward the tab I'm on to the home page with the ability to back click to the tab I was on. Someone needs to re-think this feature. I would really like to have someone on the development team address this issue.

I did not ask for tab grouping. I do not want tab grouping. And then when browser grouped tabs without my requesting it to; and would NOT allow me a way to un-group them, providing only the option to "delete tab group", which when exercised deleted all the tabs, not just the group! Now, I don't f-ing want firefox anymore! Why act like microsoft and shove features down our throat without explanation or option to chose or not chose?

So, I recently encountered this problem: If I close the main Firefox window while a private window is open, then when I open a regular Firefox window, I find that all pinned tabs have been reset, and I have to set them again.

This problem has never happened before, so I figured it was clearly a new bug and I should report it.

I asked a friend, and yes, he also encountered this problem.rt it.

I found the tab groups more annoying than useful, so I went into about:studies and removed it, but doing so just makes a study entirely disappear with no way to bring it back if you misclicked, so that made me wonder, is removing studies permanent? Is it impossible to opt back in once you've opted out of a particular study?

I'm not particularly regretting my choice in this case, but it made me nervous how easy it would be to lose access to a feature just by accidentally clicking the wrong thing.

I love having the ability to group some of my tabs but I'm wondering if it's possible to create "subgroups" of tabs inside of a "group". For instance, it would be very confusing & even chaotic to have one tab group named "Computers" that has tabs for sites where I buy computers/parts/software, sites where I go to for support for my hardware/software issues, & sites where where I can read reviews about the up & coming new hardware/software. However, the chaos would go away if I could have 3 tab subgroups (Shopping, Support, & News) UNDER a "top level" tab named "Computers".

From what I've been able to find on the Firefox website, this capability is not yet available but I'm wondering if it's something that's currently in development. If not, I would like to suggest that it be seriously considered. I realize that some people could take this kind of capability to the extreme, with hundreds of tabs organized using multiple "sub-tiers" & trying to develop something to support the extreme cases would be a nightmare. However, the ability to even two levels (groups & 1 level of subgroups) would be a HUGE improvement over the current situation.
