I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

I'm putting off upgrading Linux as I have many hundreds of undocumented addons which will be lost and would take forever to attempt to remember how to re-install.

(in fact I might just switch to macos and try using homebrew).

It seems very harsh that upgrading Firefox has been prevented by linux mint for years now.

Yes Homebrew is perhaps the way forward! Life would be easier with just one O/S as I need Macos anyway for adobe lightroom.

My version of Firefox is 108.0.1 -- I am running Windows 10 on a machine that Windows says is not capable of running Windows 11

My installation of Firefox resides on my D: drive. It uses quite a bit of space for cache and other things on my C: drive but it starts and runs on my D: drive.Now I am forced to update, but I can't get the installer to recognize an installation on the D: drive and update it. Instead it makes a new installation on my C: drive and I lose my appearance customizations, history and bookmarks.

I have never believed and cannot accept that an application absolutely MUST reside on the C: drive. It's lazy programming (something I used to do for a living). I can't believe Mozilla programmers wrote an installer that insists that Firefox must live there, so what am I missing? How do I tell the installer to find and update my existing application?

Thanks for your help. I feel as if I am missing something that ought to be obvious.

Hello,

I am confused about how to update Firefox. I have a 10 year-old Mac which I have never updated (if it ain't broke, don't fix it, is my motto), and I do not know what operating system it has. I am not sure how to continue.

All the best, Patrick Burger

Presently my firefox installation is on my C: drive (disk 0), however it tends to be overworked so I want to move my D: drive (disk 1) is there a simply way to this without having to uninstall and then reinstall firefox?

How do I set my home page with my yahoo mail account? I looked under your help section and followed instructions and it didn't work. I am currently setting up my new computer.

After the update to 128.5.1esr the browser restarted and it had the default search providers again. Why??? I was not prompted to approve it, there was no notification either. This is the st*pid sh*t which pushes users away from Firefox.

I absolutely hate Bing in the first place.

I'm guessing there is a new update to Firefox. Now I am getting messages saying "Web site will not allow Firefox to display the page if another site has embedded it". Well so far 3 different sites I go to regularly have shown me this, and there is no option or any means I see to get to the feature on that web site that I have been using for at least a year. This morning when I started firefox and it came up with a page I had previously left open, last night, now I can't to the content on that page. I really need to get back to that information. Is there some way I can tell Firefox that I would like to see the information I am now not allowed to see? If not I will try and see if I can go back to the previous version of firefox and figure out how to prevent automatic updating of firefox in the future.

Thank you for considering a new feature. However, this feature of a new sidebar is in the way on my screen. I have it setup for use in a very specific way. Adding a sidebar that I cannot turn off without going into "about:config" is a very bad idea. It made a mess of my space. Yes, even that 1/2 inch of space messed up my spacing. Please ask in the future before making any changes that alter the size and width of my screen space. It's already jammed for work.

I saw an option for donations here. If you ask before making anything that alters the screen layout, I'd be willing to make a donation. But this was just upsetting and has stolen over 20 minutes of my work day. I don't have that kind of time, especially with my colleague out on medical leave for possibly months.

Earlier today I was trying to watch Prime video and I kept getting an error saying that Firefox wasn't updated (which it was). I looked up some solutions, one of which suggested turning the DRM setting off and then back on. That was a mistake, because after that, any time I opened Prime or netflix, the error I got was "Firefox is installing components needed to play the audio or video on this page. Please try again later. "

Then, I looked that up and found out that my Widevine was just not installing. So, I found an alternative way to manually install it, which shows that it is installed in the Add-ons Manager, but I keep getting that error and nothing works. Prior to this my Netflix was still fine and working.

I've tried a few other things including closing firefox, refreshing firefox from the troubleshoot settings, and restarting my computer.

I am out of ideas, and I wanted to see if anyone can help me before I have to jump ship to another browser.

I seem only to have issues installing the Nightly build. I have successfully installed Firefox's main, beta, and dev builds.

I received the following error/message when installing it. (see attached images)

This issue occurred on a fresh install of Windows 10 directly from Microsoft's image creation tool. I upgraded to Windows 11 and experienced the same behavior. I used the tool Revo Uninstaller to uninstall previous versions of FF completely and used the tool to clean and purge any leftover registry entries and directories. No errors or entries in Event viewer.

Anybody run into this issue?

Hello,

I'm trying to update to firefox version 133.0. My O.S. is Ubuntu 20.04. I've untarred the tarball to ~/firefox/firefox-133.0/.

If I startup the new firefox, I receive the following error message: "libxul.so, undefined symbol: gdk_window_show_menu".

I also tried firefox version 120.0, except the result was the same.

How can I fix this?

thanks.

A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

In Firefox add-ons, the 'Recent Updates' section can be accessed through the cog wheel icon. How many days of updates does it cover? I'm asking because I don't want to miss any important updates. Thanks!

I am a survivor of a brain injury and many things do not connect and I am not a tech person. I don't even understand the choices there are for me to ask a question! I cannot use any FAQ's or topics for help because I will not remember them when I need to use them. I need to know how to download to a USB drive; step by step directions/instructions do not help me. Is there a solution? I would like to purchase sewing machine embroidery designs online and then download them to a USB drive to insert into my sewing machine in another building. Microsoft has been no help with this. Any help would be very much appreciated and thank you.
