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?

I have recently switched computers, and since it has been a while, I can't remember the setting on the 'about:config' page that I need to change to where when I open a new browser tab, it opens at the end of my list of tabs, rather than as the next tab. 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.

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.

When I open Firefox, all my bookmarked sites start loading at the same time. I have unchecked, the "Startup Open previous windows and tabs" option in General Settings. I also deleted, and added Firefox again, but all sites are still loading on opening Firefox. (Chrome browser is fine.) Any ideas? Thanks!

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

When I middle-click a link in Firefox, it opens in a new tab, but it also switches me to that new tab immediately.

I’d prefer to stay on the current tab after middle-clicking, and just have the new tab open in the background just like google chrome does. Is there a setting to stop it from automatically switching?

Thanks!

im having issues with my tabs as there are now two sets of tabs one that is empty basically and seems to be treated as the main one and the other that is all my other tabs... but when i try to switch to them it switches my screen so other apps like games or messaging apps no longer are visible yet the still appear to exist

Three days ago this started happening. When I mouse over the Firefox icon on my task bar, I get a long vertical list of open tabs, the majority of which are blank. When you try to click the X (that appears on the right side of the list when you mouse over a blank space) nothing happens. In the past few days it showed a random mix of blank tabs and open tabs. Yesterday it only showed the open tabs at the top with a long list of blanks below. And today it's only showing the one tab I have active (despite having up to five tabs open before I took the picture).

Before this all started happening, it used to show large tab previews (not just text) that run horizontally along the bottom of my screen when I hover my mouse over the Firefox icon on the taskbar. Now it's just a list that goes vertically with all these blank tabs.

How to return things to normal? (tab previews horizontally without blanks)

I'm running Windows 11 Home, Version 25H2, OS build 26200.7623 and Firefox: 147.0.1 (64-bit)

Thank you, John

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.

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...

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.

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

Are tab groups like containers i.e. isolated from the others, so thay I can access sites logged into different accounts for instance or separate browsing experience/cookies ?
