I have noticed a bug with how the Firefox icon appears when launched in the Windows 11 taskbar when the never group option is enabled. When Firefox is launched and is the only application open in the taskbar, there is no label present next to the icon like other programs have when launched. There is the little line underneath the icon though indicating it is launched but that is it. As soon as I open another application though, the label will also appear for Firefox. This is only a minor annoyance but is definitely as bug at least for me and should be pretty easy to fix. I will attach screenshots of the behavior. In the first screenshot, you can see that Firefox is open but has no Text label like it is supposed to. The second screenshot is as soon as I open a second application.

I am on Windows 11 Home 23H2 Build 22631.2792 Windows Feature Experience Pack 1000.22681.1000.0 Firefox Version: 120.0.1

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

I am using Firefox 120.0.1, and I have difficulty to take screenshot.

I tried to press shortcut key and button in toolbar as shown in the attached image, but they didn't work.

Is there any good way to fix this problem without reinstall firefox app?

WILL YOU STOP THAT PATRONISING "HMM, WE'RE HAVING TROUBLE FINDING THAT SITE" MESSAGE NOW

IT IS OBVIOUS THAT IT SHOULD SIMPLY SAY " NO INTERNET CONNECTION" IT IS INFURIATING.

DO IT NOW OR I WILL KILL MYSELF.

I set the browser to Open previous windows and tabs at restart, on General settings, but it always opens blanc, not saving any tab from the previous session.

How can I correct this issue, if it is one, please?

Open this url https://openfde.com/intro.mp4 and firefox shows "video can't be player because this file is corrupt".

Chrome is fine.

I have a new PC running Kubuntu 22.04, with Mozilla Firefox 120.0.1 (64 bit) installed. Standard, the system window title bar was hidden. But I wanted access to the "Move to desktop" menu and wanted the title in the title bar. So, in "Customize toolbar" I checked "Title bar". The title bar reappeared, but a complete border along the Firefox window became inaccessible, and when clicking in that zone, it effectively clicked in the window behind. In particular, the complete menu bar is inaccessible, as well as the scroll bar on the left and in the bookmarks sidebar the fold/unfold. And Mozilla Thunderbird 115.5.0 has the same annoying behaviour. Even when hovering over some menus in the Mozilla window, you can sometimes see reactions from the window under the Mozilla window. On older Kubuntu computers (up to 18.04) with older versions of Firefox (up to 113.0.2) and Thunderbird (up to 102.11.0) I do not have that problem. How can I get at the same time access to both the system title bar and the menu bar ?

Hello, currently using 120.0.1 (64-bit) for macos and would like to know how to change behavior: When i'm trying to modify url in tab i'm currently working on and press enter/return it opens modified url in new tab for some reason. But when i hold option it opens it in current tab, is there any way to make it as default behavior? Thank you very much👍

The computers bookmarks after September 28 and before December 1 2023 are missing as well as the internet history in the mozilla browser only. I see no possible way of restoring them. I see no way to contact mozilla directly about this either.

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.

I think it has to do with cookies, but I can't figure out what to fix. I have my tracking privacy set to strict. Twitch has permission to use my cookies and site data (Settings -> Privacy and Security -> Cookies and Site Data -> Manage Exceptions). All of the other websites that I have granted that permission to have no problem remembering my device, but Twitch does. I looked at this post already and my account was already set to these settings. How do I make Twitch remember by device? It's annoying to have to go to my email and use a one-time passcode every time I log in.

For over a week now I am receiving a popup from 'The Spruce' with the popup header being Mozilla Firefox (see Spruce.jpg). The popup has a facility to disable notifications from www.thespruce.com and I have selected this many times yet the popups keep coming several times a day. (see Spruce2.jpg). I have also visited the Spruce website and there is no unsubscribe link. I didn't subscribe in the first place and had never heard of The Spruce before this. Why is Firefox facilitating this spam that won't be disabled?

When trying to click on links inside PDFs, the url is changed to undefined, producing an error message. For example, a Hostgator article is converted from https://hostgator.com/help/article/how-do-i-change-my-dns-or-name-servers to https://undefined/help/article/how-do-i-change-my-dns-or-name-servers

I have tried clearing the cache, troubleshooting, and get the same result in safe mode, and reverting back to Firefox default settings. And I still get the same result. I've attached an image of the error message.

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

Greetings Firefox Community

As I long time user and supporter (have donated and even got a shirt to show!) I have never had any issues with my beloved FF. If anything minor had happened, I would always find a quick fix on the community forums.

This one is an odd ball: for a while now Firefox forgets all saved passwords but only after a cold reboot (not a restart or sleep).

It's my elderly mum's laptop, which I manage for her using a remote desktop app. It's a fairly new Asus Vivobook with Win11, fully updated and free from viruses and hacks as we have installed paid versions of both Malwarebytes and HitmanPro.Alert. My Windows desktop runs exactly the same OS and those two security software, and my FF never ever forgets anything! The only difference is that her Windows and FF are set to the Italian language while mine is English.

After trying a "refresh", I exported her passwords and bookmarks and took the drastic step of completely wiping FF and even removing profiles. Reinstalled the latest x64 version and the problem is still happening.

Had a good look at both security software to ensure there was no funny setting to cause that to occur, fact is the laptop also runs Chrome and Edge with all the same saved passwords yet those two pesky browsers never forget anything!

Personally, I'd much prefer for her to continue to use FF rather than the other two, so I am shouting out for HELP, please! Hope someone has seen this and/or knows how to fix it.

Many thanks in advance and Merry Christmas to all! Cheers Paul Perth - Australia

I can't see the SYNC option in Settings so I...

Use about:config to change identity.fxaccounts.enabled = true I can now see 'Sync' in Settings When I go to "Sign into Sync", after I enter my password, it hangs for 10 seconds, then says Working, then always just hangs there forever. If I login to Mozilla using a different tab, it signs in ok.

I have tried this after successfully changing the password, and after restarting firefox.

I am using the latest Firefox version.

Any suggestions gratefully accepted.
