Dear friends, I recently realized that Mozilla Firefox does not support Windows 7. At the same time you want people to prefer your browser. Why did you stop supporting Windows 7. I think that window 7 is an OS used from thousands of users. I prefer to use this OS and Linux Mint. So, I do not understand your policy not to support this OS. Thank you in advance for your answer!

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

Firefox updated to 113.0 and moved tabs to top, above the address bar and the bookmark toolbar is now on the bottom under the address bar ... Is there an updated CSS file I can copy that will restore bookmarks toolbar above the address bar and the tabs below the address bar? So the order would be: Menu Bar, Bookmarks Toolbar, Address Bar, then Tabs Bar? This really is hard to work with. Thanks!

Team, I am a longtime user and supporter of FF. I can't tell you how much I love the the layout of Firefox on Windows in v. 133 with the vertical tabs. Just as important is the fantastic, new font rendering. Thank you so much. I used to make multiple adjustments to the font in about:config when I installed FF on Windows. Now, the fonts look fantastic out of the box. Great job, team!

Since Mozilla Firefox web browser v127.0 (released June 11 2024) the manual installation of the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) do not work anymore!  :disappointed_face:

So, when you go in any higher version of Mozilla Firefox web browser then v126.0.1 (released May 28, 2024) to this web browser Menu Bar -> Tools -> Add-ons and Themes -> Extensions -> Install Add-on From File..., and then try to manually import-install the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) into the Mozilla Firefox web browser, and from this HDD location:

C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\Browser\WCFirefoxExtn\WebExtn\signed_extn\adobe_acrobat-1.0-windows.xpi

The Mozilla Firefox web browser will say during this .xpi file installation: "This add on could not be installed because it appears to be corrupt"!  :disappointed_face:

However, in any Mozilla Firefox web browser version prior v127.0 (released June 11 2024), this manual import-installation of the adobe_acrobat-1.0-windows.xpi file will be most successfully installed in a Mozilla Firefox web browser without any problem!

I also create the most detailed and step-by-step post on the Mozillazine.org Forum and the Adobe Forum about all of this problem:

https://forums.mozillazine.org/viewtopic.php?p=14985444#p14985444

https://acrobat.uservoice.com/forums/.../48914657-mozilla-firefox-since-v127-0-cannot-install-anymor


So, please help and advice further. Thank you in advance and best regards!

My C hard drive is almost full. How can I get Firefox to run from the D drive? I tried copying the files there but it would not run. Do I need to edit something in the Registry? I'm using (for as long as I can) Win 10 on a Dell desktop. Latest version of Firefox is installed.

Thanks for any assistance.

I looked at the system requirements page at https://www.mozilla.org/en-US/firefox/141.0/system-requirements/ . For Windows devices, the operating systems supported are listed as "Windows 10 or later".

In October 2025, Microsoft officially stops providing feature and security updates for Windows 10. However, they offer consumers and businesses the option of enrolling in 1-year, 2-year, and 3-year subscriptions for Windows 10 devices which will provide another 1-year, 2-years, and 3-years of additional security updates. You can read more about this at https://learn.microsoft.com/en-us/windows/whats-new/extended-security-updates

For those individuals and businesses who will be enrolling devices into the Windows 10 ESU program, will Mozilla continue to support Firefox on Windows 10 after October 2025, at least for those receiving security updates through Microsoft subscriptions? Or at that point will Mozilla consider Windows 11 to be the only supported Windows operating system?

Thank you!

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;

}`

Having just used Windows Update (on Windows 10), the screensaver lock screen comes on with my chosen picture AND four large buttons for weather etc. I didn't ask for the buttons, and don't want them. Is this a Firefox issue, or maybe a Windows issue? Do you know how I can stop them coming on please? (Firefox v. 132.0.2 current)

I have just logged on for the day and the Side Bar has changed. It now has an extra layer making it wider which now pushes a highly used website page off the screen which is very annoying because I don't want to reduce it's zoom any more.

I use the Side Bar to bookmark various links within this website as shortcuts to navigate it.

How do I remove this unwanted extra layer?

Please find attached a Snipping Tool file.

The unwanted extra layer is the bar down the left showing my Bookmark icon on the top and the Settings icon on the bottom neither of which I want or need and this is causing the extra width to the sidebar which is upsetting my viewing. How do I remove this new bar?

Hi All, Apologies if I've missed something, but I can't find an answer anywhere. I've got a fresh install of Firefox version 133 running on Windows 10, and I can't seem to install any add-ons. When I click the install button from the add-on's page, it just sits there with the loading animation and seemingly does nothing for several minutes. Attempting to right-click on the download button, "save link as", and hitting "install add-on from file" using that saved link as another user suggested from a similar problem does nothing at all; there's no feedback whatsoever. The add-on I've been trying to install is U-Block Origin, but I've tried this with other add-ons to the same results. The only other thing I've tried is installing one of the recommended add-ons from the add-on page directly, Privacy Badger specifically. This causes an actual window to pop up telling me Firefox is verifying the add-on, but nothing happens past this point. It just sits there, eternally attempting to verify the add-on with no progress ever made, and no error message ever spitting out. I haven't found anyone else with this exact problem. Hopefully I'm missing something obvious and I can feel really silly about the whole thing soon. Thanks much!

All the Best, G.B.Bari
