I have lots (~100) of tabs open, distributed among windows and virtual desktops. Every now and then the laptop fan starts running wildly, and I identify a CPU hogging webpage in about:processes. How can I now switch to the open window/tab of that webpage to close or unload it? I would expect a click (or context menu item) within about:processes to bring me there. Currently I have to scan through all desktops/windows/tabs to find the page.

I tend to have a lot of tabs open at a time and even with the Customize Sidebar > Hide tabs and sidebar checkbox ticked, it is still distracting at times. Could you please help me find a setting/way so that I can hide it and make it re-appear when I hover on it only. Kinda like how we have on windows taskbar? Much appreciated.

Hi! I´m a big shortcut user and a year-long Firefox fan and user. Now it´s the first time I´m using an Android tablet (Boox Tab X C) and the typical shortcuts for new tab (Ctrl + T), close tab (Ctrl + W), etc. do not work. I researched this a little and it seems to be by design. Why do you forsake us, Firefox god??

In any case, thanks for the good work folks. Love the Mozilla name and what it stands for for a long time now. Peace

Hi Everyone! I am having some trouble figuring out how to get rid of these "phantom" windows. They appear after I do a sign-in to my Google or Facebook account and it opens in a new window. The windows stay open in the background, or at least my Macbook shows them as windows as if they are still open. Whenever I click on them they just go to my most recently opened tab on Firefox and never actually allow me to click on them or see the tab. I've tried looking for them in the "open tabs" section on Firefox, and it doesn't show them there either. I added a photo to show that the "phantom" window is separate from my currently open browser on Firefox.

If anyone knows how to get rid of these, I would so appreciate your help! Thanks!!!

my top bar comes up with dozens of internet pages trying to load when I open any internet page. Have not made any changes to anything. Pita to delete a dozen items trying to load every time I open Firefox. How do I turn that off? Tried looking for way to do that for hours and found nothing.

For some time now, when opening Firefox, I do not find the tabs I opened in the previous session. I've checked that the "Open previous windows and tabs" box is checked, but it didn't help. I uninstalled Firefox and reinstalled it from a fresh .EXE file, but that didn't work either. I've searched for resources on the subject but haven't found a solution to my problem. I should mention that I'm not a computer expert and I'm not exactly young any more.

Can anyone help me?

Thanks in advance.

EDIT: Nevermind. Update fixed the issue!

As of today, when I drag left or right on the screen in the browser, it tries to switch between next/previous tabs. This happens even if there's a web app I'm using that allows for click-and-drag functionality. I can't find a setting to turn this feature off.

That tab grouping "feature" really is too much like modern software developers' tendency to roll out a new "feature" and turn it on automatically no matter how annoying some users may find it. Some times when a mouse cursor goes too far and wanders into that tab zone, Firefox starts grouping tabs. Please allow us to turn the thing off.

Por algum motivo, meu firefox está abrindo conforme a página inicial configurada, contudo, sempre deixei para retornar com as guias que ficam em aberto e por algum motivo, meu firefox bloqueou a opção de abrir já com as guias da sessão anterior.

Não sei se é coincidência, mas está acontecendo após esta ultima atualização (19-05-2026), alguém mais está com este problema?

Minha alternativa será abrir minhas páginas todas novamente, e configurar para o firefox pegar as URLs como pagina inicial padrão...

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

I've noticed for awhile that when exiting Firefox (currently 150.0.3) open tabs no longer close. When I re-enter Firefox (new start) I no longer get my home page. I've tried all key combination of exiting as well as the X. I searched this community and WWWeb and found nothing usefull.

Thank you for your attention to this matter. Rodney

On Android, with the OS set to use the bottom 3 buttons (back, home, app switcher) and Firefox set to use bottom address bar, when multiple tabs are open, closing a tab causes the "Tab Closed" bar to cover the lowest tab in the list.

This causes problems when trying to close multiple tabs because it's no longer possible to hit the "X" marking on the next tab without swiping the box away first.

I don't recall exactly then this became a problem, but it was fine until a few months ago and then a change caused this issue to start.

There's a lot of empty space in the box, maybe smush the box to the left side of the screen so the next tab is still able to be closed?

So, forgive me, I'm a little frustrated right now, but I needed to move an Open Tab to it's own window, without the use of my mouse (yes, it's having issues right now), but: I used to do this by tabbing to the TAB in question and pressing <Shift> F10, which opened a context menu with a Move To sub-menu. Now the menu didn't have that option. see pic below. ...Yes, I was able to do the same via, File | New Window, and coping the address to it with Windows cut/paste and <Alt><Tab>. Still I would like to know how to get to the TAB context menu option without the mouse.

Hi everyone Since sep-15, The "Open previous windows and tabs" function is NOT working .. everytime i have to reopen all the previous tabs. I am not sure if any update has caused this. Please help. Thanks

Firefox deleted older open tabs on my samsung phoone and my ipad. This was really gutting as these were open for a reason. I was not logged into either instance as I wanted to preserve my privacy as best as possible.

Please stop fixing things that aren't broken! I just installed the new version of Firefox for Android and I hate having tabs strewn across the the top of the screen. Many of them are personal and private and I want them hidden from view. The previous version of fox for Android work just fine for me, this one doesn't. Is it possible to remove them from you?
