Firefox Community Forum

Tab groups being returned to Firefox desktop a couple of months ago is one of my favourite features, which makes my life significantly better. However, I cannot find any information on its presence in Firefox Android. Is it added and not well documented? Is it not added? Is there a plan to add it to Firefox Android?

A few days back, the browser "+" symbol used to open another tab at the top right of the browser window disappeared like a bad odor in the wind. Performed a search and located instructions on line that explained using 'about:config' settings to restore the symbol. It worked and I was browsing wonderfully again.

After closing the browser a few days later, the + symbol has vanished again upon restarting. Have searched in vain online to locate the parameter in about:config that I need to reset, but cannot locate it and I do not remember the parameter to search. CRS problem.

I can go into the Customize menu and drag a folder with a + symbol to the menu bar but it behaves differently. Just want the convenience of clicking the + symbol to automagically start another tab.

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

Any Ideas what is going on? About July 21st, 2025 I started noticing with a couple of browser tabs open, a new tab opens autonomously and flitters in the new tab name area, what "looks like a TagID", then closes by itself. I define "looks like a TagID" as something that looks like a tag at end of article link in popular newsletters I see, and appears in the url bar of the linked article.

The occurrence of the new tab happens when I open the browser, within 1 minute and occurs randomly during the session, perhaps every 20 minutes.

My first suspect/assumption is I am always signed into Mozilla when I open Firefox 141.0 (64 bit), processing an update now, Aug 5 2025. I have subscriptions to VPN and Monitor and I have sync (passwords and bookmarks) with my mobile instance of Android Samsung Galaxy phone.

My Desktop is set up as Windows 11 pro with one employer InTune acount for Microsoft but I limit that work to Edge browser.

Почему при нажатии клавиши F11 (полноэкранный режим) не сворачиваются вертикальные вкладки? Почему нет ручного скрытия вертикальных вкладок?

________________________________ Why doesn't pressing the F11 (full screen) key minimize the vertical tabs? Why is there no manual hiding of vertical tabs?

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

(btw my browser is Firefox Nightly) Don't get me wrong, I love having vertical tabs. It's less busy than the horizontal tabs and I can look through my tabs more quickly. But, the way it's implemented sucks - It makes the layout of the webpage pop anytime I use it; there is no keyboard button attached to opening and closing the tab (I have to go through my horizontal bar to open my vertical bar); and recently my browser forgets the sidebar settings, meaning I have to re-check the "Hide tabs and sidebar" setting.

Bonus request Can the sidebar just go over the webpage (i.e. like the application menu) instead of squishing it? I'm ok with having some webpage features temporarily covered if it means I don't have to see the screen pop into a new rectangular shape every time I switch tabs.

Why FF is resetting all tabs during an update, like the last one? The tabs cannot be restored automatically. It does not happen with each update...but it's annoying when you have several tabs. Thanks for taking that into account. Yves

Hi there,

I enabled the new tab groups feature the other day - having used it in Chrome on my work computer, I know how useful it can be.

However, it doesn't seem like there's any way to collapse tab groups and just leave them as like a square to be opened and closed just by clicking on the tab group? Am I mistaken here? Every time I try to click on the tab group to close it, the tab group just changes color (i.e., goes from blue background with white text to blue text on a white background) and none of the tabs are collapsed into the group (i.e., they just stay on the tab bar, and I'm shifted to a different tab).

Is this happening for other people? Is this what is supposed to happen? Is there some setting that I need to enable? I've tried seeing if it's conflicting with any my add-ons, and I haven't found anything just yet. I'm awfully confused, so I'm hoping someone can help explain what might be amiss here. Thanks in advance.

Support Firefox to be able to use different tab view modes on different windows! For example, two Firefox windows on different monitors, in my situation below:

- One on a 1920*1080 hori screen, with vertical tab sidebar disabled - One on a 1080*1920 vert screen, with vertical tab sidebar enabled for this window only in this case.

It brings much more convenience, at least for situations just like mine :)

I can't keep my daily tabs open on Firefox. Every day, I have to put them back up manually. What's going on? I was using Waterfox and it seems to be hacked, now Firefox is not reliable either.

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.

Version 140.0.4 (64-bit)

As the title states, if you have a private window open and you close your main (non-private) window and attempt to relaunch Firefox (mine is at the taskbar) you will then encounter a window with none of the previously opened tabs and simply a single fresh tab. This is despite having the setting to continue browsing where I left off in the settings ("Open previous windows and tabs") enabled. Luckily the lost window can be recovered by going to History -> Recently closed windows -> "___tab names____"

A few times now, I have inadvertently opened a second Firefox window. The original Firefox window comes up with two pinned tabs. If I close the original window then when I start Firefox the next time, it no longer has pinned tabs. I am running Win8.1 on a desktop system.

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.

Hello everyone, Until a few days ago, Firefox version 140.12.0esr included a button to "Save windows and tabs of the current! session." Unfortunately, this feature is no longer available in the current version, 152.0.1. However, for many Firefox users, saving the windows and tabs of the current! session is absolutely essential. What options are there now to resolve this issue? I would appreciate any suggestions! If there is no way to restore this feature, I, too, will unfortunately have to switch browsers after 20 years as a Firefox user. Many thanks in advance for your help and any information. Best regards, Norbert
