I've exactly the same problem as described here. https://support.mozilla.org/de/questions/1442833

This is a privacy problem, because most of the time when I open a website like google.com, I don't want to be logged in so the website can identify me. I only keep a container tab for such a website around, so I can open it if I explicitly want to be logged in.

Hello,

how can i disable firefox usage hints like "Try tab groups for less clutter, more focus"?. It opens up if i open up a certain amount of tabs. Is there anything i can disable in about:config?

Thank you.

With FF 140.0 on both WIn10 and WIn11, new tabs opened automatically then closed after less than a second. Initially I thought this was due to malware, but on inspecting the History, I found the source of this annoying behavior:

// SidebarUtil.tab.js

// This is just a placeholder file to be loaded in a temporary tab to check if a sidebar is open and how wide it is.

Is there a way to STOP this sidebar checking with its tab opening/closing without disabling Java entirely ? Is this annoying behavior really necessary in FF ?

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

Regards, G.W.

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

There are many tabs open in the firefox window. I'm closing the firefox. I'm opening it again.All tabs opened during the previous opening disappear.Either a new page or a single tab opens. The settings are set to "Open previous windows and tabs" (Image 1)

I go to "Firefox View" ---"Open tabs". (image 2) I see 2-5 windows there.In this case, there are 3 windows.WINDOW 1 is my main window with the tabs that should have been saved and opened when firefox was launched again. I close all tabs from unnecessary windows with a cross.Only window 1 remains. But when restarting, an empty or different window opens again.And again, there are a lot of unnecessary and incomprehensible windows on the list. Previously, a window with restored tabs from the previous session always opened. Question: 1)How can I restore the normal recovery of the previous session when restarting? 2) Tell me.I can somehow switch between windows (Firefox View" ---"Open tabs)(Image 1) Thank you.

With vertical tabs and expand on hover, clicking on the X box rarely closes the tab. Sometimes I have success if the pointer is on the left or right line of the box. Not having luck on the center of the box. Has been true for several weeks. With hover off, clicking the X works fine. I am running Windows 11.

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____"

When I click on a bookmark, FF opens it in the current tab, overwriting the site I had open. I have to add a tab, then click on the bookmark to have it in a new tab. This is an annoying extra step. How to I change it? I already tried the open links in new tabs instead of windows. Makes no difference On or Off

[I use firefox on Mac, Windows, and Android, but the issue seems to effect me mostly on Mac and Windows) I'm just guessing this to be a browse issue. However I won't miond the post being moved to a more relevant sub-forum.

I keep arriving at this solution when searching for a solution to the increasing number of sites using the irritatingly abused stay/leave page question-dialogue box which pops up when i want to leave a page. The common solution appears to be https://userscripts.org/scripts/show/23865 However, when this page loads, I just get an empty box which looks like one of those ones which normally contain scripts to run or stop running certain things, or even to add or embed items etc.

When researching I often need to load lots of pages top go through. however, when i then need to close them all, i end up manually having to complete these irritating dialogies which are OBVIOUSLY really meant for pages where you may be filling in a form, or editing something, and perhaps have not completed filling it in. However, many sites irritatingly abuse this and just add the feature anyway. It just tells yiou they are dodgy rather than trustworthy. Any up-to-date advice as on July 2025? Any trusted new extensions/addons for this as with auto-cookie form-fillers perhaps?

You seriously need to remove the AUTOMATIC tab grouping, it's annoying as hell!

I know there's a workaround, but that's beside the point. You don't break into someones home in order to re-organize it, that's just bad practice all around.

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 want the browser's tab bar to display like the homepage, instead of disappearing after opening a webpage tab bar. I don't know if I can accurately express my meaning, but I will attach two pictures

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!
